I just got my car all together, i assembled it from a shell, went to fire and no starty. figured out i have no injector pulse.

changed ecu relay in pass kick panel and tested circuits before and after relay change and the proper ones seem to be getting 12v. i'm stuck here.

the connectors at the back of the intake(blk&wht-round), have you tried cleaning the pins/female conn.? also, when you turn on the key can you hear the fuel pump prime? do you have a shop buddy that can help you test voltage at the injectors while you crank it? those 2 round connectors are notorious for corroding up....

X2 on checking all connectors and especially ground wires. Could be a Bad PIP sensor in distribuitor? I would turn key to run and then use a multimeter to see if each injector plug is getting 12 volts, or put a noid light on each one and spin the distribuitor by hand to see if any light up or not.
