starts and stalls
Put another ECM in.Swapped Prom. Car flashes right away. Much quicker than before when it was running and staying running,rough. Did the A to B wire Code test witch revealed a bad CTS. Replaced that .No difference. Have checked the TPS for the .54 and it shows 4.72! WTF? Moved the throttle open with very slight change, 4.69 I believe. Going to check for spark next, then the Spark Mod. Have read alot on here.Anything you could add? Thanks.87' GTA.

Re: starts and stalls
If it’s starting it has spark. Have you checked fuel pressure?
As far as the tps goes if it’s really high the ecm will disable the injectors.
You should check the actual reading at the ecm pin c13. You might have bogus information in the data stream.
