Brain Teaser

Hey

I have a real brain teaser on my hands and i know this is a mustang site but this time my question is not about my mustang its about my 1991 Ford Probe LX with a 3.0 V6 and a 5-speed. I have a fuel problem that i cant seem to pin point. I have no power to my fuel pump, the switch in my trunk alows current through it and I just replaced my relay control module which supposedly contains the fuel pump relay but it made no difference. It turns over fine and has spark but idk what else to do the fuel pump is good and i had a mechanic with a computer try to scan the system and find it but he was also unable to put a finger on it either.
All the books ive seen on my car say the fuel pump relay is under the dash on the driverside on the relay panel but my car does not have it.

Thanks for your time.
willing to try anything you got for ideas

Re: Brain Teaser

How do you know the pump is good? Not sure about the location of the relay, but I would check under the hood near the firewall on the drivers side. On some Fords, there is a small secondary ground wire coming off the battery. If this loses connection, the fuel pump will not kick in.

Re: Brain Teaser

The fuel pump relay is under the hood in about the center near the firewall. It's actually the IRCM, (integrated relay control module). Here's the diagram.

Do you here the pump come on for a few seconds every time the key is turned to run?
