Just finished my LY6 with LS3 intake swap into my 67 cutlass convertible. Got it fired up finally today. Problem I'm having is the gas pedal (complete dbw set up from donor van, TB & pedal) is completely NON FUNCTIONAL.
The car will start & idle, but the pedal is dead...and I have double checked the wire solder connections & the clip onto the pedal look pretty good.
I've given up for the day..I will hit it again tomorrow hopefully with some good suggestions!!!
I'm pretty sure that there is no TAC on my set up..but yes everything is from the same donor vehicle. It is the complete donor harness that was sent to a guy in ATL to be modified & then tuned my PCM. He took out the parts I didnt need from the harness and then laid it out to fit my application.
I do not have a code reader, but I guess I'm going to go buy one today!!
Jon...the pedal is the one that came out of the donor van. I am using the E38 ecm. To make things worse i tried a newly tuned diffrent ecm and it wont start, swap back the other ecm and it starts idles but no gas pedal...
