nobody can figure this electric problem out!

ok...ive posted before buy im still having the same problem, CAR WILL NOT START, it sounds like i pulled the mpi fuse, im getting no injector pulse! ive checked everything!!!...have 6.2 resitance in my resistor pack, CAS has resitance, swapped ECU's, CAS, and EFI relay and still nothing, i dont know if this would have anything to do with it but, i swapped a 92 head on my 90 block, will my 90CAS work fine with a 92 head? i pulled my cas out and cant here the injectors ticking, but i tested the injectors and they work fine.....the other day though i tried to start it and it gave me some putt putts liek it was gonna start and almost did start but the longer i cranked it the less putts i got!, and now today it wont even put!...i dont understand whats goin on!..and help is greatly needed!!!... oh and maybe this might have something to help u...when i "key on" the pump does not prime for a few seconds, but when i pull the return line off when cranking fuel does poor out so maybe that has to do with an electric prob? am i missing a sensor that needs to be plugged in?

Damn...similar problem to me...Im getting fuel pressure but no damn spark...Im sick and tired of messing with this POS

Pull the MPI fuse and check the voltage between the the two terminals with the key on. You should have 12-14 volts. Try that with the EFI relay as well. If you have already tried that, ignore this post.

theres a ignition module that gives the car spark too,did u test that out??those are known to go bad alot on 1g dsms

i'm having the same problem where is the ignition modual that you are talking about?? only one i know of is the power transistor.

yea its also called the power transistor,did u check to see if dats badd??mines got wet once and i replaced it started right up

 

[blu_gxl]

well my problem is intermitten and i've already replaced the power transistor? so i'm leaning to the ECU being bad now great!

 

[92redman]

A bad ecu very well could be the problem. I had one that intermittently missed fired in two cylinders...

hmm, that's interesting that's what i have very light spark in 2 cylinders that's why i thought to replace the coil packs. but, the cylinders with the light spark were not on the same coil?
