i"m just completing building one car out of two. one was a bare shell and the other was a wrecked 97 z28. i've swapped every nut,bolt, and bracket. i'm at the point where the car should run however..... it cranks and has spark but not getting fuel. i jumped the relay on the pump and it will work but still no start. when i was doing the tear down i set off an alarmthat i didn't know it had and i unhooked the battery. didn't think anything of it. not sure if this has anything to do with it. the security light comes on and goes out briefly when the key is turned to run but i think thats normal?? however the service engine light never comes on at all. i plugged in the scan tool and it wont read anything..just says check connection. the wiring harness is all plug and play... 2 grounds under the dash (rechecked) 3 grounds under the hood (rechecked). any ideas?? how to test ECM? alarm reset??
