Hi. I have a 1998 3.8 mustang. Car suddenly stopped, and found out that no electricity is going to the fuel pump. I ran a wire to the fuel pump and the starts it. I changed the Constant Control Relay Module and still don't get power to the fuel pump. Fuses are all good. The only other thing I need to check is the Inertia Switch, but if I still don't get any power what could it be? Can anyone help me please?

Complete the circuit

Check your ground, not for the pump but for the relay module..
I would consider a wiring diagram and jump the connection at the module to see if the wiring going to pump is not damaged. I`m not a big fan of the factory modules myself, much of the time the solder breaks down and they fail.. I`d wire in a standard 4-pole relay, there way cheaper..

Good call on the bypass, most probably would of assumed the pump was bad.

Thanks for your response. I went home yesterday and checked all the wires. From the CCRM, the Inertia Switch, to the fuel pump and found out that I had a peeled wire at the connection at the fuel pump. So glad to be running again.

I have another question. I want to rebuilt my engine pretty soon. It has over 240,000 miles already. Still in okay condition, but anytime soon is going to die. I want to make my V6 the fastest and strongest V6 out there. What should I do besides a supercharger to get more power?
