hi all im new to this but need help asap. i recently converted my z31 na 2+2 to a turbo. i followed the redz31.net webiste to the bone and got everything connected. while i was adding my turbo i also changed the water pump(as it was leaking) and the timing belt. I go on to start the car but it will not stay on. it turns on but will cut off once the rpm come back down. i need help bad im going nuts. anyone please

first things first, run codes. if you dont know how to do so look here. XenonZ31 ECU Diagnostics

ok i tried that and it displays the car speed sensor, the idle and the fuel temp sensor but my question is this. the ecu that im using is from an 85 turbo model and my car is an 87. can it be that its displaying wrong errors. the other thing is that i have trouble accelerating when i turn on the car and it drops the rpm i give it gas but rather than accelerate it dies.

ya the ecu's are different. the 85 has a single feed injector and the 87 has a duel feed. so the ecu has different ways of controlling it. but the codes would be the same for every other sensor in the car. so fix the codes and see what happens.
