Hey everybody i have an 89 s15 with a 4.3l tbi. i started it up about a week ago and it ran very rough and barely idled. i turned it off and checked a few things, and when i turned the key again it cranked and never turned over. it has spark and fuel getting to the throttle body but the injectors are not spraying. It ran fine until this. Heres what ive done so far in the past months.
Rebuilt throttle body
New fuel pump
New fuel filter
Checked fuel pressure
New icm
Checked fuses
Traced out wires I could find
Ohmed injectors
I also have 12 volt getting to injectors, I'm out of ideas so any help would be greatly appreciated
