I am begining to hate my engine, I cant figure out the problems, and more syptoms are starting to appear!!
For starters, I have had to replace the fuel pump fuse 2 times in the last two days.. Both times I was stranded in the road.. Luckly I had enough sense today to take one of the ones from a light.

Next Im having power surges, asside from having almost no power.. I am still having a high idle problem and I still cant get the electronic ignition to work..

ARGG!

if i'm not mistaken, the fuel pump and the heater blower are on the same fuse.
usually, it a problem with the blower and/or wiring to it ...

check yer ground. and vacuum leaks.

forget about the carbs. every single 914 with carbs i have seen lately had at least as much problems as the FI cars.

Don't get carbs!

What do you mean power surges?

High idle indicates vacuum leak.

If it runs, the electronic ignition must work?

When does the fuel pump fuse blow? I just had this problem last weekend. Two very smart guys on this board steered me straight to the problem. The AAR connection!

Stock fuel pump in the stock location? I'd focus on the fuse problems for starters. Your fuel pump might be going out.

Check vacume leaks, ya ya, I have been doing that for a month now....

I dont have any of the heater suff installed.

I dont have the standard wireing for the fuel pump, spent forever trying to get it to work, but had to run alternate wireing.

I never said a thing about carbs..

My AAR is junk, I dont even have it connected.. Anyone have a working one cheap? Or knowlege of how to rebuild one? ( I am manually opening and closing off that vacume)

Power surges, ie sputters, backfireing, ext.. all the bad things. (though no oil leaks)

I have points in the car now. I have electronic ignition on the bench and tested it and it works, just not in the car.

I blow the fuse when I am leaving an area, ie when the car is accelerating from a park..

Fuel pump stock location (kinda).

I know you've heard this before, but I'll repeat it anyway. Start with the basics!

Did you disconnect the wire to your AAR and tape it up?

Sputter and backfire could be dwell or timing.

Blowing a fuse when accelerateing sounds like a wire moving around and shorting out, or something loose.

Andrew, by saying your AAR is not connected do you mean electrically or it's totally out of the car? If it's still in the car and not connected via its wire then it is open causing the vacuum leak. If it is by passed (no vacuum hoses to it but still connected electrically it could still be causing a short whereby poping your fuses. By your past posts I assume (I hate that word) that you already know this (but since I never assume) I figure I may as well tell ya (IMG:style_emoticons/default/smile.gif) I know what you're going thru. Mine did this too (but it was something else)........ bad injector (IMG:style_emoticons/default/mad.gif)

I vaguely remember seeing a car show on tv a few years ago where they used some kind of smoke generating device to introduce smoke into the car's vacuum system (by the brake master cylinder, I think) to detect vacuum hose leaks. I can't find such a device at Eastwood, though. Can you use propane from a propane torch to see if it increases engine speed when near a vacuum hose?

You can spray a variety of things at the joints of an induction system to find leaks, but I generally use brake cleaner or starter fluid. Some things cause the engine to rev up a bit and others cause it to stumble, but any clear reaction means there is a leak. I like brake cleaner because it evaporates completely, rather than leaving a mess. If you are using starter fluid, or any other flamable agent, be careful around headers and open sparks!

my 40's work juuust fine thank you. ugly thing to say, but it's the owners not the carbs. if they're old rebuild them or try Air Cooled Engineering, acevw@aol.com. get a GOOD linkage, clean your jets, and put the filter in front of the pump.

When I say accelerating I mean from 0-2 mph..

and just to be clear I am sure that I dont have 95hp, im guessing 70 tops..

I didnt tape up the aar, but I dont think I need to worry about that...

Jake, you mean clean everything like this? The bat tray is new and very purdy

Ya know I keep thinking in the back of my head that its an injector, I need to stop delaying and buy an injector cleaner..

As for checking for vacume from places I have only found a small leak from the intake runners,but that is it..

I dont think its the gas tank thing, I just had it out and I cant remember anything specific about it.. I think I shaked it to tell, but I dont think I have anything, I might have even put a magnent trying to get some metal.. dont know, I might check that..


Hope this info helps..

You should fix that vacuum leak from the runners... As for your popping fuse, obviously something is grounding out some place; start looking for stray wires. It might be a good idea to pull your injectors and make sure none are leaking and all have a good spray pattern. Also, it goes with out saying to make sure the engine is in good health (valve adjustment, compression, ect.). Good luck.

Andrew, Fix that vacuum leak now!

If you don't think you have to worry about that untaped wire from the AAR, read the thread I posted last week entitled "fuel pump short". Its on page three.

1st point!!


DO NOT USE BRAKE CLEANER TO FIND AIR LEAK!!!!!! Why you might ask? READ THE CAN!! I did just this the other day and my eyebrows are still growing back...THINK FIREBALL!!!

The points or the spark plug ignited the fog of brake clean that I was using, what the hell, I could not find the carb cleaner. BOOM. What the hell was that, then I read the can. highly flammable.....so take your chances, anyone for a car-b-que????

good luck, herb
