I have posted on here once before. I drove the car and parked it. i went out next morning and wouldn't start. i noticed no check engine light on or digital message center. Checked all fuses and relays i tested power to inertia and fuel module after that its not sending power to pump. I have sprayed starting fluid in air filter and it starts but does not stay running. No pulse to injectors i am guessing the message center and fuel is tied together. Any suggestions will help. i have a test light and fluke meter.

Hello,

It sounds like two possibilities here. You either have an open in the wire going to the fuel pump or your ground could be bad. Let's start with the easier of the two and check the ground first. The ground that controls the fuel pump is actually the ground for the fuel pump control module, which controls the fuel pump. It is ground #408 and is located below the center of the rear pkg tray. Make sure that this ground is clean, tight, corrosion free, and making good metal to metal contact. I have included a wiring diagram of your vehicle's fuel pump circuit in the diagrams down below. Please get back to us with what you find out.

Thanks,
Alex
