Thanks I'll add that to the things to double check - I did have the engine out so anything is possible.
I found a pretty good section online of a GM service manual that discusses port injection symptoms.
The hard starting and engine hunting troubleshooting should be good reference sections.

Here's the link to print Section B (Symptoms) of Driveability and Emissions - Fuel Injection (Port) 6E3-B:

Yesterday I made a little progress.
I was able to determine that a slightly loose PROM chip was causing some starting issues affecting the fuel pump and spark intermittently.
I replaced the cork on the access cover to ensure it stays snug in place with the cover on.
Also, I went under the car and found yet another exhaust leak at the header / collector flange.
I removed all the header wrap permanently and I'm picking up some copper gaskets this week.
I've also ordered new stock 24.9lb/hr Fuel Injectors to replace the Accel 26lb/hr ones since the LT fuel trim was in the 140's for both banks (lean).
Also warm hard starts are solved by two squirts of gas in the TB - the old injectors seem to be causing the lean condition.
Apparently it's pretty common for old Accel's to cause hard starting - hopefully replacing them fixes my problem.

Finally, good news!

The new fuel injectors solved the hard starting problem
Yesterday I also upgraded the header/collector gaskets to the copper ones I had previously ordered.

Nah! No sense in spending money on the paint. Simply because this car is going ot blow that fresh coat right off the first time it goes down the road. Right, Ryan?

I know it's still an eyesore but I kept modding the body and hate sanding, so I figured get the mechanical side right first.
Unfortunately I lost my job last week, so now I have more time to work on it but no money
My goal is to have the car all black before the summer.

I hope you didn't take me wrong. I just ment that the car is going to be sooooo fast that it will peel that fresh coat of paint off. I didn't mean anything about how the car was unfinished.

No problem Paul, I knew what you meant.
I was trying to give marlboroman an update.
Cheers,

My baby had to spent another winter outside and I noticed a few minor fiberglass cracks, so I took some time redoing and improving the problem areas...
