Fuel Injectors not working properly

Good morning,

The injectors are controlled by the engine ECM. When the ECM sees a crank signal or the engine is running, it will command the injectors to flow fuel.

The most common failure is the ECM for this. I attached a picture and procedure for you.

Some replacement ECM's may come with a replacement PROM already installed in them. If this situation occurs, remove prom from old ECM and install in rebuilt ECM.

When replacing a production ECM with a service ECM, transfer the broadcast code and production number from the production unit to the service unit. Also, during replacement, the PROM, and if equipped, the CALPAK must be removed from the ECM being replaced and transferred to the new unit. Refer to "PROM, REPLACE" and "CALPAK, REPLACE" for procedure.
