Well, I have spark (obviously,because it runs), it has fuel in the rails, and a new fuel pump. When the crank sensor went on my dad's 85.5 944, it wouldn't fire, of attempt to start. I'm still leaning towards the relay being bad.. I'll check around for one.

Thats exactly the thing to start looking for. My 944 had a no start problem for a while that I narrowed down to a crank sensor, cleaned it, and it fixed it.
Then you have the problem of Air Flow Meters causing cars not to run.
My advice there might be to find a used one dirt cheap. I'm not a super mechanic but my 944 has a temperature switch that can cause the car not to start. The 928 may or may not have the same thing. Maybe someone will chime in and say one way or the other.
Still you may be wasting a lot of time on what may be your Jetronic computer. Thats why its important to check the relays and fuses for things. I'm not sure I can post about competitor shops on here but 928intl.com has a fuse and relay chart under the technical tips. They are good guys with some cheaper used parts. I prefer Tom.

I don't know how my 82 hasn't gone up in flames yet. I filled my V with a few gallons a few weeks ago after replacing the injector fuel lines with what I thought was the proper rated fuel line.

The right stuff should be here tomorrow.

I'll look into that. I didnt get a chance to clean the ground as it was getting dark outside.

Fuel pump is running so that eliminates a relay issue with it.

From what i have found when searching for the relay, the High beam is the same?

The PO said that it had been run recently, and the PO of my 82 bought the 82 from the guy i bought the 83 from. He said that it ran fine when he went and did a compression test on it, then he found another 928 and didnt buy this engine.

I drained the tank and what was in it wasnt that bad. But the stuff in the fuel rails..Rather nasty, wouldnt have burned. Took the cap off of the end of the fuel rain and let it blow that crap out.

I thought that the fuel pump pressure was near 70psi?

And my 82 doesnt have any relays at all in it. the PO started parting it out and sold those, fuel tank, tail lights, console,windows controls,door locks,ect.

Thanks!!

I'm pulling back a couple of years but I thought I remembered some other 24 relays in the relay box. No doubt the '83 was a little different from my '84 but I could have sworn there was more 24s.
Landseer, why don't you have a 928 track car? The Euro 84 928 5 speed makes a hell of a track car. You know they raced a 928 at Lemans in 1984. It came in 28th or something but it finished the race.

There are about 5 "24" relays in there (i think) . The fuel injection relay isnt a "24"

Okay, yeah I'm trying to think of what I did to cross reference my relays. These guys are probably telling you right to just build a jumper for the fuel injection relay. Basically its a wire crudely attached to 3 of the relay pins so you can connect the 3 inputs of the relay board where the fuel injection relay went. Its a hand made direct relay basically. I'm not sure if anyone has explained that. I have one that I made to keep in my car so if one of my relays tanks I can get the car home.
If you're trying to do relays, on the pin side of your relays, there are numbers 30, 87a, 87b etc. What you will need to do is find a relay that matches the numbers (and positions) on the relay you pulled out for your injection relay. I think its coming back to me and its a 5 pin relay. Junk yards with newer VW, Volvo, Saab, and some BMWs, all have Bosch Relays in them. You can scrounge around and stay cheap, but you have to have a working relay with the numbers in the right sequence.

Ill try to build a jumper when i get a chance. Would you happen to have a picture of the one that i would need to build? Thanks!


(and yes, it is a 5 pin relay.)

The one I built is simply two pins from a relay with a wire that connects the two. To build a 3 pin jumper I would just cut what I have in half and wire another wire in between the two ends with another pin connected to the end. Hence, 3 relay pins wired together.

I-o-I
I

The car only runs when i pour gas in it, and only fires when i dont.

ok, if i wire some pins together,ill probably end shorting it out and blowing myself up. I dont know what wire needs to go where or anything like that. i am totally lost.

I dont know how to build a 5 pin jumper.. Since there are 5 slots, wouldnt all of them need to be filled?

Is a 944 fuel injection relay the same as a 928? i didnt find one in the box of the 944 that looked correct.

Thanks!

Only if you want to burn everything up!
Find someone locally who can help, before we read that inevitable - 'car went up in a ball of flames' post.

First off, i have never messed with a 928 in my life, dont know a thing about the fuel injection in the car, or what relays do what. I am plenty serious, i want this car to run and drive. If i was not serious about it i would not have bought it. I apologize for not knowing that much about a car that i have never owned or messed with before.

And as i have said in previous posts. "i have not had a chance to clean those grounds" because the night i was trying all that, the time i got a chance to work on it, it was getting dark. I dont know about you but i like to be able to see what i am doing when i am working. Not working in the light of only a flashlight.

By looking at the picture of the relay box below, my relays are a bit out of order.

The next time i get a chance i will check EVERY GROUND i can so that i wont be "pissing in the wind" anymore.

Thanks.

you speak of a 5 speed -- It is an 83 automatic

The chart i found and am using, is this: http://928intl.com/repair/Relay/earlyrelay.htm

928 International is the s*&% right. The guys are pretty helpful. Tom got me some great deals on parts. We like the chevy mechanics who come to learn how superior technology works! :)
Also something you are missing is fuse number 16 that runs the fuel pump, the warmup regulator, and something else rather important to the engine. You might check this to make sure its in good shape.

I am working on an 83.,, Not an 82, the 82 doesnt have any relays nor an engine. It is basically a rolling shell right now.

My fuel pump runs, so at the moment, (not being able to be at the car) im guessing that it is in ok shape.\

Thanks!

Look up how to bypass the factory alarm. This can also cause it not to start. It's worth a try and is easy to do.

Peter

Huh, didnt even know there was a factory alarm. Ill try to figure out how to do that.

My 83 doesn't have a factory alarm. FYI

The car runs when he manually puts fuel in it, and doesn't run when he doesn't.
The car only fires without the manual fuel injection, and his fuel pump is running.

This would tell me that he has a fuel delivery issue, and not an alarm or larger electrical issue. I haven't seen that he has a fuel pressure gauge on his fuel rails, so we don't know if the pressure is adequate, but let's just assume that it is until we know different.
His car is probably trying to fire on any fuel that the cold start is trying to provide. The fuel from that will only run the car for a second or two. My theory is that the injectors are gummed up and not allowing fuel to pass through to the cylinder.

If you have a mity-vac, you can psuedo-clean your injectors one by one, by removing them, putting a vacuum on the hose end, hooking a 9V battery with a switch to the electrical connection of the injector, and dropping the injector into a can of B-12 Chemtool. Work the switch until the chemicals start going into the injector and the vacuum on the mity-vac starts going down.

Reinstall the injectors using new EFI hose.

Good Luck

Take ur time learning and studying and hands on. Just think you can break records when you build the 82 next. *have a work shop manual (wsm) cd? download cannell.uk?(spell)

when you first get your pcar all this that you been throwing out and getting feedback on, granted applies. 1. miraculous things happen when ground and fuse cleaning thorughly yes.

Can try finj cleaner techron first, if previous owner has done the below recently . (hoses or clips ..... arent ancient looking) Post pic engines(compartment) fuel inj/rails , -- to be safe do them.
2. +1 (stepson) you need to take your finj out and send them to which hunter(finj cleaning serv.) for 100 bucks and in 7-10 you get them back. theyll give you instruction what to send . the pintles on the finj will be replaced , uniform spray pattern. yours arent spraying or correctly orbroken. screens inside them they replace. yours are gunked/dirty. if they dont replace orings 8small and 8 large (16v) are needed. while there sent out do....
3 fuel rails. cut off old hose(careful of barbed end dont damage) get new fuel hose (30r9?) mm? cut each to length 3in?. get finj clamps 32 (16v ) .
4. fuel injector connectors, buy crimp or solder option kit w/ shrink tubes. cut each off appropriate lengths and your brittle broken ones will be new/clips. *noid light check each for elect. pulse.
5. rest of fuel (30r9?) lines many ft and 3 sizes in eng. add all lengths of sizes, take pieces/sz to napa? and buy fts of whats needed. possibly clamps if needed. Inspect parts that hose is to and from being connected to, fuel regulators.... Fuel sys done?

6. Then do all the many ft /sizes of air/vac lines. vac lines done?

7. fuel pump is good fuel filter?

8. buy a finj to have as spare , urs is possibly ok.


***** the fuel inj relay you say for fuel inj and high beam i think finj fit for 928 high beam fit for 944. not its the same one used in 928. ** a handful of 53 relays (5- bucks a pop good to replace multiple fits) Of course keep posting!!!!!!!!!!!!

Dont know if 83 applies ^
