Would the ICM, RPM, or PCM keep my fuel pump from coming on?

Hello,

Inoperative fuel pump can be due to a number of things. It could be because of a bad relay, wiring issue, or a bad pump. The mentioned modules typically will not impact the fuel pump functionality.

First check the fuel pump relay. It is located in the fuse box under the hood (see attached diagram).
Look for any burnt pins or corrosion. You can also test the relay.

If the relay is good, you will need to check to see if the fuel pump is getting power.

If it is getting power to the connector, then the likely it is a bad pump.

I have attached diagrams below for your reference.

Let me know of any questions.
Thank you.
