Did you find a ground point beneath the air pump valve, itself located over the O in the word Porsche on the pass side cam cover?

I think there are 2 on the right (pass) cam cover for 82 car. one is buried under the airpump valve near the o in Porsche, you must remove that valve to access it. Those two grounds handle all the important engine management items including computer.

third ground at back of right cam gear cover, aka micky mouse ear, is less important.

Side notes:

Have you jumpered the alarm to take it out of equation? Seated each electrode within the rightmost power distribution plugs on CE panel? Removed the CE and cleaned the holders?(reseating the fuses hasn't always worked on the 928's I've rescued).

Safety: Remember that embrittled fuel lines on 928's have flambéed a lot of cars, they've gotta be replaced, especially if somebody's hands are routing around in the engine compartment. And 82 original front lower ball joint carriers need to be replaced with steel carrier versions.

i cant put them back where they originally were, as explained, the threaded portion in the plastic piece at that location has broken free. i had to cut the wire of, since i couldnt get the bolt out. necessitating the relocation.

I was able to spend some time on it and got it running. when i cleaned the grounds before, i didnt remove the brackets for the smog valve. i decided to yank it all out once i realized the possibility of the brackets not making good contact w the cam cover as a last ditch effort plenty of corrosion had built up between the brackets and cam cover. i had also added leads to the ground wires before which i thought would have eliminated the possibility but apparently not. they were grounded according to my diagnostics, but not good enough.

so the moral of the story, i guess... pull the damn smog crap completely off the cam cover and take a roloc to it before you do anything else

Congratulations -
 

Hey Mike - Glad you have this one sorted out and running. These cars can definitely be frustrating at times. We were about to break out the never fail last ditch "928 Porsche Secret Procedures Manual". In summary it recommends to "Hop On One Foot and Vigorously Twirl a Dead Cat Over Your Head While Barking At The Moon".

Great Job......:)

Michael

yea well making it run was half the battle. I am still fighting with the essentials. i.e. lights. i tore apart the washer pumps to get them working, ran new wiring to the front turn indicators, cleaned a billion connections etc. i thought i had it all done today as i finished up the wiring for the indicators, now i have a short in the parking lights, which makes no sense, as they worked fine before i hooked up the indicators, which now have their own completely isolated harness. i hate chasing wiring issues. i think i am being punished.

front light issues are usually the result of the harness getting cut just under the headlights,
where the harness is clamped by the metal tab,
the wire needs to have more slack so when it is extended it doesnt shear.
also its common to miswire the lights in the bumper ,
careful examination of wire color to the WSM will put things back in order

ill look closer at that harness to see if anything is broken, as far as "miswiring" things, like i already stated, they all worked properly after i cleaned everything and before i replaced the wiring to the indicators. i just dont understand, as i ran new wiring from the indicator fuses to the lights, its completely isolated from the rest of the harness

i guess there is a very good chance there was already a short, and by jostling the wiring about i just made it bad enough to pop the fuse, and has nothing to do w the indicators

No injector pulse
 

I have a 1989 that had this problem shortly after I rebuilt the engine. There was no current going to the injector.

It turns out that Porsche added a security feature that disable the injectors from firing if the central lock system has been tampered with. Make sure the Central lock computer and linkages are all connected if they are not connecting them will hopefully solve your problem.

If it doesn't check your computer(s). I am not sure how your model year is set up so you will have to do some research as to which connector points send the trigger from the EZK to LHC and from there to the injectors. finding out where the signal stops will show you what you need to fix.
