Re: 1991 olds 98 no injector pulse Help!
I appreciate all the help you guys are providing.
We did not know about the ground bus on the passenger side nor the drivers side they had been wrapped in tape. With the help of Mike's pictures we found them. The drivers side ground bus had turned green and had rusted presumably from the water ...

Not sure how the ECM is different than the PCM. Is the PCM the body control module?

Thanks for getting back so quick.
- We did check the body grounds. We weren't sure where they were at first so we pulled out the seats, carpet and installation in order to find them. The car has had water leaking into it and we though that might be causing a problem with the grounds. However, even ...

1991 olds 98 no injector pulse Help!
I have no ground at all 6 injectors. I have key switch volts on all injectors. I was told that the driver in ecm sets the ground for all injectors.
I replaced the ecm, crank shaft position sensor, cam shaft position sensor, C3I module, and coil packs.
Also, check engine light dose not luminate.
