Re: fuel pump problem
OK, on a 1995, the fuel pump relay is inside the CCRM (Constant Control Relay Module).
A fancy name for a small metal box with relays in it.
I have pictures of the CCRM in the pictures that the link in my signature takes you to.
Now, the FIRST thing that I would check is the fuel pump inertia shutoff switch.
This is a safety switch that is designed to turn off the fuel pump in the event of an accident.
Once tripped, it must be manualy reset.
This is located in the jack compartment.
Power flows through fuse "N" in the engine compartment fuse/relay box.
This is a 20 amp fuse.
From there, the power flows into the CCRM Pin 11 and through the relay contacts.....and out of the CCRM Pin 5
Then the power flows through a variety of wire harnesses and back to the Inertia Shutoff Switch, that is in the cargo area, in the jack compartment., then it goes through another wire harness and to the fuel pump.....then to ground.
The power to energize the coil of the fuel pump relay (inside the CCRM) comes from the PCM power relay, which is in the engine compartment fuse/relay box.
The way to reset the Inertia switch is to press down on the button......when it is set.....you can still push the button about 1/16".......and that is normal for when it is OK.
If that does not solve the problem.....try checking for power at that point, relative to a good ground....with the ignition ON.
