HI. I'm trying to find what wires I need to connect to from the TIPM that will allow me to bypass the relay. Fuse M22 is before the relay, so I can't tell if I have a bad relay, or bad pump. I have the color of the wires to the pump, but I'm missing the color of a wire from the TIPM that I can use to energize the relay that only comes on at key on. Would anyone have a wiring diagram that I can see to help me choose the wires I should use? Thanks for your time in this matter.

Good afternoon,

I attached the wiring diagram of the fuel pump for you to view. The relay is part of the TIPM or the fuse box.

I highlighted the wires from the TIPM to the pump but the controls are internal in the TIPM.

I attached the location of the power module for you. It is a plug and play module if you replace it.

I really appreciate your response. Thank you. I did have another question. So If I run a temporary wire from battery positive to the dark blue with orange wire, I should hear the pump turn on in the fuel tank, correct? That would tell me if it is a relay issue or fuel pump issue. I have ordered a relay kit to bypass the TIPM relay with my own incase it is a fuel pump relay issue. If I do need to bypass the relay with my own relay, do you know of a wire that supplies 12V at key on that I can use to energize the relay? Also, I didn't see m22 in the diagram, Just m33? My truck listed above is a 1500, Hemi. Thanks again for any info. I really appreciate it.

If you run a wire to the dark blue/orange wire, the pump should run.

If that is the case, for the relay, you need a constant 12 power and a key on power. Both can be used from the fuse box.

Thank you again. I really appreciate it. I tested the circuit by pulling off the backshell of the connector and adding a temporary wire to the pin location. I then put it back together and checked the voltage on the wire when cranking. There was 12V. This means the relay works. I then pulled the M22 fuse and ran my temp wire to batt pos. to drive the fuel pump. No noise. I believe I have a bad fuel pump. I really appreciate your answers.. Thanks for taking the time to answer this so quickly. It is appreciated.
