Hi guys,
I spent last few weeks to prep on my newly acquired 2.0 and it's finally in the car! But she doesn't wanna wake up.... I know our Bay has been cold lately...but today is beautiful!!!
It turns over, has fuel pressure around 30psi when cranking(20psi soon after when the key turned off), static timing done after points gap adjusted, all the electrical connections checked I think, and what else???
Actually there're at least 2 concerns I can think of. When I got the motor, the dizzy rotor was pointing somewhere around#4 position when the TDC mark was showing in the round window. So I moved the gear in order for rotor to point #1 as I confirmed the valves were loose. But wondering if I did it correctly. I took the gas tank out as I installed stainless fuel lines. The tank was sitting in my garage for about a week or so then it developed some rust. So I cleaned inside with rust remover. But I might not have rinsed it well enough. New fuel filter still looks clean after uncountable numbers of attempt of starting the motor. New fuel sock is in the tank.
So I am stuck now
What do you all think I screwed?
Thanks in advance,
kkid
Are you starting the engine with it in the car o on an engine stand?

I didn't hear you say you had a good spark at the plugs. Seems too obvious, but.... Do you?
sorry, I gotta p/u my daughter from school.
If you have a dwell meter hook it up and measure the dwell while turning it over. Should be 45-47.
You said that the fuel presure drops after cranking, does it go to about 0 shortly after you turn the key off?
I'm putting my money on the distributor drive gear is misaligned/improperly located. If the timing is close and you have fuel and spark, it should at least cough...
Fuel lines at fuel rails are crossed?
By changing the distributor drive gear around whn you got the motor back from the engine builder, you probaly have it 180 degrees out of time. The is only one correct position for the cam, crank and distributor to all be timed correctly when the engine is assembled. Let's assume the engine builder did it right, but the engine was turned over by hand after it was assembled, probably when they installed the fan & alterntor belt.
The firing order is 1-3-4-2. That means whenever TDC comes up to the timing mark/pointer, the rotor will either be pointing to #1 or #4 cylinder (and no others). Switch the distributor drive gear back to where it was when you got he engine and then set the static timing of the distributor. I bet it will probably start right up. I once had a similar problem with a 1960 Alfa Romeo Gielietta. The PO's previous mechanic had installed the distributor shaft drive gear wrong by 180 degress and then moved all the plug wires on the cap by 180 degress to make it run, instead of tearing the engine down to install the distributor shaft drive gear correctly. There is a reason the distributor shaft drive has a gear at one end and an offset "notch" at the other.
I thought these distributors had a slot that only permits you to install the distributor drive in the right possition, in which case you have to change the timing by rotating the spark plug wires by 180 degrees clockwise or counter clockwise, either way ends up in the same place.
Also, check for spark while you are at it.
Lennies914 and I had the same problem, it turned out to be the injection trigger points in the dizzy were sticking! We opened up the dizzy, replaced the trigger plate and it started right up!
If you changed the distributer 180 degrees, change the spark plug wires accordingly.

Thank guys for the advice.
I will check the spark today while my friend is here.
Actually, my daughter told me to wait till Christmas.

One easy trick is to just pull a plug wire, plug in a good new spark plug, hold the threads of said plug to the block....Or some good ground.... And have someone crank the starter while you watch the spark.
That bugger should scare you with a nice fat blue/white spark. If it is weak and yellow then we have a troubleshooting track to go down.

I tried your method and had a decent spark. Can't tell if it's white, blue or yellow but it didn't look weak. Did only on #2 plug wire. Should I try on all other terminal wires too?
Thanks,
kkid
Checked on the injector to see if it's working. Tried on #1 injector while cranking. I placed a paint spray cap underneath the said injector and got some gas in it. But I see some gas leak from #2 injector even though electrical plug was not attached. Is this normal???
Hi
I always examine for the simple solution,
1. Check that TDC lines up with no 1 cylinder.
2. get someone to crank the motor and first check spark is coming from the coil by holding the coil wire a few mm off the block. If there is spark check the no 1 lead.
3. If there is spark at the number one lead pour a small amount of fuel down the intake manifold , if it fires and runs for a second or two. if no spark.
WARNING---do not pour fuel down the manifold whilst turning the motor over. If it is not properly tuned and it back fires it will ignite the fuel in the container you are holding. No need to explain, that's is bad news.
4. If no spark check the points gap.
5. Spark but no fire , check fuel supply.
I just pulled my own tank and the screen and filter were clogged. I undertook the Por 15 fuel tank restoration process and bought a new screen and filter plus changed all the lines and fuel hose.
Just my 2c worth on top of the other good advice.
Oh, forgot. If you pull the plug from number 1 and think you are at TDC all you need to do is put something soft like a plastic straw into the plug hole if the piston is at the TDC the straw will only go into the cylinder about 2 inches if not the straw will go in about 6 inches, just saves a lot of valve checking etc. Must not use anything hard like a screw driver.
That is not the flywheel, it's the cooling fan. That IS a timing mark which may or may not indicate TDC. I think It may indicate 27 deg BTDC. The timing mark on the flywheel is viewed through a hole where the trans and engine cases come together, from underneath.
Assuming both pictures were taken without rotating the crank AND assuming that is the 27 deg BTDC mark then It looks to me (not an expert) that your timing is retarded 27 deg when its not running. That may keep it from running.
So I wonder... If you rotate the dizzy clockwise 27deg, to match up with the timing mark on the fan, would it start???
At least I think it's clockwise (not an expert).
Good luck!
Zero is TDC. The hash mark on this fan is 27° BTDC. For a 2.0L, you'll want approx 34° at 3500 rpm. Depending on a couple factors, 34° may be too much advance. You don't want any pinging, so be prepared to retard if necessary, then make a new mark for your specific requirements.
Read this Pelican article on timing ... http://www.pelicanparts.com/techarticles/914_timing/914_timing.htm
Mine has only one mark for 27deg BTDC. I have read there is some variation in these marks depending on the engine size/Mfg date... I set my timing to show the red line in the notch at 3500 RPM, fully advanced.
I believe the flywheel mark in the little window should be TDC for #1 or 3 depending. It will alternate, one then the other.
Pulled the gas tank today and sent it to a local radiator shop in my area.
Will watch it to be cleaned tomorrow. So I can take it home and install as soon as I pick it up.

3. If there is spark at the number one lead pour a small amount of fuel down the intake manifold , if it fires and runs for a second or two. if no spark.
Done but motor did not start this way.

Im certainly no expert here, but this really sounds like a timing issue. If you put a small bit of fuel into the intake manifold, you should have had something happen, even if it was a backfire from one end or the other, unless your timing is simply way out of whack !! Just my $0.02 worth !!
Check the ground wire on the points plate in the dizzy to make sure it's got good connection; engine will not fire if it's bad.
And double check your CHT connection to make sure it's tightly connected at the wiring harness. I've had both of those little dumb things happen to me in the past and it took me too long to figure them out.....
The zero on your fan is tdc. That and the notch in the distributor body that the rotor points to is correct. The timing for a djet is at the 27* mark on the fan like Euro's pic shows. Never 34 with djet.
Try pouring more than "just a little" fuel in the manifold then crank it again. If you have fire at the plugs, and fuel in the manifold, it should start.
Please be outside when trying this and have an extinguisher handy. Safety always with gasoline.
Should I check the compression on the engine with new rings?
It looks like I should abort the fuel tank cleaning until we discover the problems(s).
gotta take my daughter to dentist...
Have a great day(night), guys!
Thanks,
kkid
Maybe the harness wiring is different from 73 to 74 and doesn't match the 74 ECU!??
Maybe the po swapped the harness and the other stuff to try to make it work. A 74 harness with 74 ECU.....? Now you may have a 74 harness with 73 ECU....just saying..... I don't know if they are different but I have changed the pin out on an early 1.7l harness to match the 2.0L later car! When I swapped the engines!
Man .... I keep reading through this post and it still sounds like it is an ignition timing issue. I will soon be stabbing my distributor back in and I really hope that I dont have the hell that you have had !! I still think that if you pour fuel into the intake, you should have some kind of a reaction out of either the intake or the exhaust. It may be a backfire, but you should get some kind of reaction. If you dont get any reaction, then I would think that the timing is way out of whack. If it is crank/cam timing, then your compression would be off. If it is ignition timing, then your engine could be firing with the piston at the bottom of the stroke and you would get no reaction. I was doing some research for when I get ready for my engine, and I stumbled across this article. The second half had (in my opinion) more information for starting off than the first half. I hope it helps you out, and this problem is solved soon !!!!

I just got the 74/2.0 going last night. the problem was the injectors were not getting spark. tested with 4-nobs lights. the hot lead was disconnected...fixed that and it fired up. you can check the injectors with 3 volts (2 1.5 AA batterys taped together), listen for the "click". test each one and also check for ground at each one. then check the harness for current usuing the light(s). Then track back to trigger points and power...
Merry Christmas to all!
My engine now squeals like a big when turned. Thought it's a belt. So I removed the belt then turned the motor by hands. It still squeaks when the crank shaft goes up to little before TDC for either #1 or #3. It might be a fan that is touching the fan shroud. Because I removed it once to replace the seal(the builder did not change it!). I can check it by removing the fan and turn the crank the shaft by hands to see if it still makes noise. Maybe I can try to remove the impeller fan with the motor in the car. Will see....
Thanks in advance for your thoughts!

Update with news
Good: I am on the road again! Damn it! How fun the car is!!
Bad: Still running with the old motor! Damn it!! Don't tell my wife about it.
Yes, I pulled the new motor out and put the old one back in there. That's the only way to get the car running at this point and started right up as usual.
The new motor still squeals (by hand rotations) even if it's out of the car, even with/without the fan. The internal noise seems to come out from of the case or between the case and head area. I now realized it cranked with the starter slower than normal. Will post the piggy squeal on youtube later.
This is what I did or changed/installed on the new motor(maybe more but as far as I remember).
1. New crankshaft seals f/r
2. New injector seals
3. Valve adjustment
4. Adjusted the end play and shimmed to the spec
5. New plugs
6. New ignition wires
7. New ignition points
8. New ignition condenser
9. Changed passenger side and corner engine sheet metals(motor came with sheet metal with holes for a/c compressor)
10. Changed hardware for alternator bracket
11. New fuel filter
12. Stainless fuel lines from Tangerine Racing
13. New fuel hoses
14. Rotated the dizzy drive gear to get a correct alignment
15. Static timing
16. New oil and filter
17. Primed the oil system prior to the starting
18. Recharged battery
19. New dizzy cap
20. New exhaust studs(6 out of 8) on the heads - the motor came with heat exchangers installed but 5 nuts were rusted and unable to loosen so had to take the nuts and studs all together then installed new ones. 1 stud was loose and looked to be glued with an epoxy like a JB weld!
21. Cleaned gas tank then installed a new sock and hoses underneath
22. Newer clutch assembly from other motor(less than 10k miles)
23. Alternator seal(rubber spacer)
24. Stainless engine sheet metal screws from 914rubber.com
25. Terry's accelerator cable
26. added TDC(white) and timing(red) marks on the other edge of the cooling fan
27. New seal and washers on taco plate
28. Readjusted fuel pressure @ 29PSI+ with a gauge
29. New intake runner hoses
30. Disconnected cold start valve fuel hose for fuel pressure gauge
31. don't remember...
My advice --- Don't buy a motor that has never been fired up or tested. It may not run like mine. Even if it's rebuilt it may not run specially if it's a resale item that a seller has no idea how it's built. Buy an engine that is still on a car or with a recent bench test result.
Now what should I do with the motor? Should I take it to Mark to examine? Well, my time and money were well spent for this phase.
I believe the seller won't take it back after we found out it has a failure. So I will tear it down to find out the problem and rebuild myself.
My journey will begin.
Thanks for reading.
Have a great day!

Hey guys!
Spring is here. So I started working on my poor motor today.
Someone gave me a suggestion that the squeak noise maybe caused by a dropped dizzy drive gear washer in the case.
So I took the gear out to see if the washer is still with it. Yep, the washer came out with no problem. It wasn't dropped in this case. Does the gear look OK for you guys?
I also tuned the flywheel a few cycles by hand again. It's not hard to turn with the all spark plugs removed. But there is a noticeable hardness at a point in the revolution. Somehow the squeak noise seems to have disappeared today.
Where should I go from here?
kkid
A squeal sounds like the fan is rubbing the housing.
