RevWife's 914, Pulling a 914 back onto the road Options

[Dave_Darling]

They moved the pump up front in 74 i believe, maybe 75. Something to do with fires, or fuel smell in the cockpit.

In 75. To cure vapor lock issues. (Which I have experienced a grand total of ONCE in my 74 in the past two decades.)

Well then. Maybe I misunderstood- plastic lines run the length of the tunnel? Apparently, in its history, someone replaced the lines IN the tunnel with steel but joined them to the plastic via 7/16 fuel hose and hose clamps, inside the tunnel, under the rear access panel.

I inclined to leave them as is.

[Mikedrevguy]

Well, I put the project of replacing the fuel lines through the tunnel on hold while I ponder this.
Turned to the fuel lines in the engine bay. Picked up the line, trusting what the proprietor said I'd need. Nope, 18" short. Oh well.
In pulling it all apart, pulled fuel rails and injectors, learned that the injectors don't like brake clean. But also discovered the seals were mostly good- except for the last one which had seated cock-eyed- so back to import parts- fuel line and injector seals- but alas, they are closed.
Also, dropped battery off at Les'- they tested, charged for several hours. Never would hold anything. So, I, pick g up new battery tomorrow, and sizing tires too.
Running rivieras, any suggestions/recommendations on fitting in stock height wheel wells?

this is off topic but.... on Weds the 11th part of the medford cruise is the park and shine for imports out at the porsche dealer on hwy 62. Thinking i will take the pumpkin out. stop by if you got time.

ok now back to your regularly scheduled programing

[Dave_Darling]

Not quite the length. Below, you can see a photo of a cut-away center tunnel. (Literally cut, I think with a plasma cutter.) Note that the front of the lines are metal, but most of the length of the line is plastic. No clamps, just flanges for a strong friction fit.

Dave, thanks for the Mage. That helps.
Thanks for the heads up, hndyhrr. May have to find my self out there.

[Mikedrevguy]

got new battery, checked turn signals, flashers, headlights.
one motor works, the other not. (pass side works)
tried test on the headlight motor - spun the black disc on motor to cause activation:
pass side works,
driver side not.
is this indicative of a bad motor, or no power, or??

thanks,
M

btw - engine bay is redone with new fuel hose.
front fuel lines will be redone when acquire new pieces parts, which are in the mail as we speak.

[Mikedrevguy]

Getting closer to firing the motor.
Drained oil- about 5 quarts worth (IMG:style_emoticons/default/dry.gif) (IMG:style_emoticons/default/sad.gif)
There was a bunch of fuel.
Potential culprit?
Bad rings?
Bad/stuck injectors?


IF we're talking about a bad injector, what are the options for replacement ?
Are type IV injectors compatible?

How to test to determine which injector it might be?

On another note: replaced the broken door latch on driver's door.- closes solidly now.

[Mikedrevguy]

compression check this am revealed I've got 130-140 psi on each of the 4 cylinders.
Other good news, the car turned over - - however was unable to get oil pressure to build, presuming that the Oil Light should go out after cranking sufficiently to test the compression. I do have the gages in the center console tore apart; might this have something to do with the oil light staying lit?

realized I should have painted the hell hole and the battery tray last night, as now I'm in a holding pattern until the POR 15 dries.

verified that the fuel pump does in fact pump fuel. that's another good thing. so just awaiting a little bit more drying time before assembling and giving a test fire.

[Mikedrevguy]

and we've got ignition!!!! (IMG:style_emoticons/default/piratenanner.gif)

however (IMG:style_emoticons/default/huh.gif)
there's a crack in one of the fuel lines in the engine bay - gonna do hardlines from tunnel into the engine bay - and go from there.

answered one of my questions:
yes, after cranking enough, with starting fluid, the oil system did charge and build pressure: the light went out.

sooo,
on to the next step.


thanks,
Rev/

[Mikedrevguy]

may be a shot in dark, but someone may be able to address these questions:


fuel lines are intact - motor turns over and, with assistance of starting fluid, will start.
however there is no fuel squiring through the jets.
pulled distributor out and cleaned the trigger points
thoughts? guidance?

also, looking at the fuse panel, the fuse supposedly for the license place light - someone put a 26 amp fuse in there. any speculation on why or what they might have been thinking?
?

thanks much.

[Mikedrevguy]

verified that there is fuel getting through system:
pulled off cold-start fuel line, cranked and plenty of fuel came through.
have fire: verified with starting fluid.
have fuel: as verified above.
fuel simply not making it through the injectors.

thanks in advance for you assistance.

relay question:
found the relay box in the engine compartment.
with three slots filled with the the 911.615 109.01 relays. the slot farthest front is empty.
what do these control.
where might I go to find out what these control?
any help would be most appreciated.

thanks.

Mike

[Mikedrevguy]

never mind; found it.

Rennlist Techarticles

had a 1/2 hour heart attack.
somewhere in the course of connecting, reconnecting, disconnecting - motor stopped turning over. key fine. power to fuel pump fine - turn to attempt to start - and just more fuel pump.
and then just as mysteriously, it began turning over again. (IMG:style_emoticons/default/dry.gif) not sure what to make of THAT. those arent good mysteries.

in course of checking grounds to the injectors, discovered that the injectors on both 3/4 share a common ground. as do 1/2 injectors. is this an issue?
diagram that Blowsby indicate they are not so paired. dont think this is of issue, but just wondering.

thanks again.

Make sure you check your point gap and it is set to the proper dwell/gap. I went through this recently when I started my car for the first time.
My car would not turnover at all until I was close on the dwell/gap.
I used the Pelican Parts article as a guide to setting it for my first start.
Sorry if this has already been discussed, I skimmed the thread quickly.
Good Luck!

[Mikedrevguy]

Thanks, PlantMan. I've had it running on starter fluid sprayed down the throttle body.
but will certainly be keeping an eye on the points to make sure they're properly adjusted.
right now, just cant seem to get the injection to function; no spray, no electircal impulse at the injectors. nada.

so, have the injectors soaking in diesel.
I removed all the relays (the universal round) tested for continuity and operation- opened them all up and cleaned/filed the points. only fubared one, but it's still operational, just ugly.
what's a good way to seal the relays back up? I'm thinking super glue may not be the right approach (I believe that was what held the one I buggered up together).

Got the interior put back together again.
installed the window/roof seals. not all together happy with how they turned out. maybe the next one I do will be better.

thanks again,
Mike

So, after a summer of other priorities got a fuel pressure gage on to determin I'm only getting 14psi.
Headed into the market for a new fuel pump, it would seem.

Did you re-furb the injectors? That is a good thing to do. It might take me a while, but I could find the vendor that did mine, or someone will chime in. I got lots of data back with mine. They change out all the tubes and o-rings, etc.... Probably to e10 gas standards, can't remember.

Then, I let them sit for several months before I put them on.... The cleaning fluid gums up. Had to send the injectors back and they cleaned them once more. Just paid 3rd and 4th shipping to and from Michigan as a stupid tax... (IMG:style_emoticons/default/rolleyes.gif)

My pump worked fine after sitting for 10 years, but it made an awful sound, so I replaced it too. I added a permanent fuel pressure gauge to the engine bay so I could quickly verify pressure when needed.

Keep working at it.

Clark

[Mikedrevguy]

Thanks for the reply, Clark.
have not had injectors referbished. soaked them in diesel for starters and will go from there.
tracking down a fuel pump - will verify that I've got sufficient pressure - evidently 14lbs is not enough to even open the injectors. so, no they are not squiring.
however, we did procure a tester to verify electrical pulse to the injector. pulse is positive.

so, relays are good, pump will be good. injectors unknown.
wi'll just keep plugging away.

thanks,
Peace,
Rev.

FWIW, One of our members vapor locked on our run after the BBQ last month. It was 95F and we pulled over after ascending appx 1500' up the mountain. I knew it would fire if would could get some gas thru it so we pushed him around and he headed back down, allowing it to get some cold gas thru the overheated FP.
