Ok, so cleaned up the pcm to ground. But before I decide to turn this car into a 50lb. tannerite target let me show ya a few things I noticed weird with the wiring. I'll take so pics as references. And post very soon.

 

Is there a way to post videos?

 

From "Manage Attachements":

 

In your "PCM to Ground?" picture, where exactly is that located? I can't tell from the picture. It doesn't look like the engine block There are two PCM grounds - G110 on the engine block, near the starter, and G111 - the stud on the driver side head near the ICM.

Above the starter, the goldish round part in bottom is the starter.Ive pretty much narrowed it down to bcm pcm opti or bad wire or connection somewhere. Icm checked out fine, Im thinking its bcm pcm or opti because Im not hearing fuel pump kick on.

 

I forgot to mention, ob2 scanner wont connect but is getting power. If that helps narrow down the cause.

 

If Im wrong tell me, but that ground (needs to be snipped, wire is corroded) would explain some of my issues... traction control button not working either. Tcs off and gauges lights are the only ones coming on. If so is there another good engine grounding location ? Maybe share the engine mounting ground with battery ?

 

The factory manual, ground distribution section, where the above schematic was copied from, shows all the grounds in the car. The “G” ground number is on the schematic, and following the schematics is a list of where every component and numbered ground is located. The above schematic shows that the TCS button and the instrument cluster are attached to G110. which is the same ground I pointed out in post #64, engine block, near the starter.

Is that car a flood recovery car? The corrosion seems to be excessive.

 

Might have well have been lol, no just neglected for years sitting up here in humidity heaven ohio.

 

So would I be able to cut back to where wire is good and extend it to where battery is grounded on engine mount?

 

I got the beast started. So that ground g110 was the fault. Fuse box (i/p) cover is not from this car, so i had to switch around some. Now fuel injectors are leaking, pulled them out, orings shot. New ones (GM) are on the way with the little sleeves above them. So I have a new delphi pressure reg Im putting on too. Pulled fuel rails off. Quick question is I think I lost the retaining clip to 1 injector. Will any do?

 

A few of these were split.

 

Original clips?

 

Rings are cracked.

 

Don't need the clips at all; the injectors will seat just fine w/o 'em, esp. w/ new o-rings. If you're the fastidious sort, you can get some from Napa or AutoZone. Got rid of mine.
