I have a socketed obd0 pr4 ecu, when I put a chip in and plug it up, I turn the key but the main relay won't click and the fuel pump won't prime, but the check engine light cuts on for 2 seconds like it does when the main relay is on, I've tried 2 different chips and tunes, made sure my chip was oriented correctly, solder joints are clean with no trace messed up pn the board. and still nothing, but a stock pr4 will start my car no problems. I'm out of ideas at this point, any way to test for sure if my chipped ecu is screwed up?
