It's a 94 Camaro Z28 with the LT1-A4. All stock except for gutted cat and a K&N air filter in the stock air box. We have replaced the Both Head Gaskets, Whole Opti-Spark (AC Delco), both O2 Sensors, MAP Sensor, Coil, ICM, Wires, Plugs, Ignition Switch(on the column), Battery (Checked all grounds also) and now it will not stay running. You can burn the tires off of it and then try to crank it 30 mins later and it won't start for nothing! :craz28: :dontknow: No SES light or any light on the dash. They come on but don't stay on. I have tried a reprogrammed PCM and it still won't crank. IF it does crank, it will run lass than 10 seconds and shut off. It has been at Mayhem Motorsports for 6 months last year and they have been stumped by this!! ANY help is very much appreciated!!!
