I'm running a painless harness on the chassis and a PSI harness for the engine.

Will find out tomorrow.... I hope so.

I had a similar problem and it turned out to be that the switched power that I used to go to the computer would lose momentary power when I turn the key to start. Kinda like when your wipers stop momentarily when cranking the engine. The power was an interrupted signal. Just a thought.

Certainly something to check first. When wiring I used the wire that previously powered the coil to ensure constant power. I also confirmed the power was live during cranking. The fact that I have spark proves the EFI harness has power as well. Goal is to get the ECM reflashed today. Hopefully the car will be running shortly

Hope you get all the issues sorted out, and have the car running soon.

IIRC the 67's didn't have IGN + power during cranking. They have an updated switch that has a second IGN + feed at the switch during cranking.

Im hoping its just in the software.

On my original harness, one of the 2 switched sources wasn't interupted that is the one I ended up using and it solved my problem. I ended up using a AAW update harness so that is all in the past. Sounds like you have figured it out. Good luck

No luck... Tuner flashed the correct program into the ECM. Got home and car is still dead. The cam code is now gone but that's all. It is still throwing the accelerator pedal code.

I hauled a** to Chevy just before they closed today and grabbed the Vette pedal they recommend. Apparently the pedal I have that i thought was for a Vette is from a Monte Carlo and has the 2 wires with a reverse pinout. Got home, plugged it in and still nothing. I'm at a total loss here.

I'm headed to the hardware store to get a decent volt meter to check the pink injector wire voltage. I'm told it is positive and the other colors are the ECM grounds to fire it.

Any other suggestions?

I would start with the connections that are related to the codes thrown.

But lets start at the beginning.

Are you leaving the main bat power connected? We had an issue with main power being disconnected then the pedal would have to relearn all over again...it would run in limp till the pedal learned then we would get pedal response.
We left the battery wire on then cycled the ignition power several times.

Are your fuses ok? Are your grounds tight? Have to watch out that your ground bolts that are too long and bottom before putting pressure on the eyelet.

Pull the connectors and inspect the PINs.
