I am not getting any power to my fuel injectors but the truck cranks and it wants to start ---

How do you know the injectors aren’t getting power? Did you use a noid light? ---

Yes i did use it and theres no power ---

usually the injectors have + 12 volt all the time on one side. the other side is grounded by the ecm when it wants to inject fuel. Are you saying the +12 volts is missing, or the pulses which ground the injector to inject fuel are missing? What to do next depends on knowing that. ---

Spray some starting fluid (ether) into the air intake ahead of the air filter while cranking, see if it starts that way ---

The ground is on the right or the left? ---

I don’t have a clue. I’d prefer to leave the next steps to the more experienced folks here, but I’m starting to think crankshaft sensor. ---

No idea which end is which. But one side of all the injectors will usually have +12 volts when the key is in the “on” position, and the other side will also + 12 volts (due to the current path through the solenoid winding), but is intermittently pulsed to ground by the computer. Do you have a way to measure voltages? ---

> [@old\_mopar\_guy](#): > > I’m starting to think crankshaft sensor. That would prevent the ecm from intermittently grounding the other side of the injector, so no fuel would be injected, but the +12 would still be measured as described above. For this problem it is critical to know whether the 12 volts is missing, or the grounding pulses are missing.
