No fuel coming out of fuel injectors?

Hi,

If you have fuel pressure to the throttle body injectors, either there is a wiring issue, or the ECM has failed. Each fuel injector is a solenoid-operated device controlled by the ECM. If you look below, you'll see that the ECM is what controls the injectors.

First, check the inj A fuse. See pic 2 for the location. When you check the fuse, also confirm there is power to and from it.

Next, I would recommend checking for diagnostic trouble codes. The truck has an OBD1 system that doesn't require a scan tool to get codes. All you need is a short jumper wire or even a paper clip.

Follow the directions in this link:

Let me know what you find.

Take care,

Joe
