injectors have a problem
on question ive looked in the books for this and the internet. but i was wondering how much power do you have to have on the F and H ports on the computer to get the injectors to throw fuel? i have around 1.5v on each how much do i need i was thinking 12v but is this right?

Battery voltage is most likey not the issue. Several of the component signals on the SE's ecu work on 5 volts. If the battery was only putting out 1.5 volts, the starter wouldn't even crank. I have doubts that the starter solenoid would even click at 1.5 volts.

I had a problem after my swap where my injectors wouldn't run. For some reason I swapped the leading and trailing ignitors and it worked.....I know if the computer doesn't see a trailing coil/ignitor pulse it won't start anything.

OK here is where I'm at all the volts are where they need to be; according to the book at least. I know the ignition system works because i can get the car to start with starter fluid. so I've heard the engine run even the F and H ports on the computer have 12v so i don't know whats going on or why its not sending fuel maybe i have bad injectors or something i don't know. any suggestions? i would like to hear from The Doc on this one. i would like to talk to him on the phone or threw pm or something because i know he went through something similar. thatks

btw..if you disconnect the harness at the injector and check to see if you have a ground on both...ya know see if you have a short.. possibly without the ground the ecu wont send out the 5v
