Cougar fuel pump relay


there is a 30A fuse in the power line to the pump. Check for continuity, if the fuse is good check to see if there is 12v on the
relay input (black/yellow wire). If voltage is correct check the Mass air flow sensor operation ( you can find the procedure at the AutoZone web site in the repair manual section for your car). The MAF sensor sends the control voltage to the fuel pump relay, if that is good then the relay might be bad. If the CCRM was bad I believe it would produce a fault code. I hope this helps,

1989 f-250 inertia fuel shut-off switch switch location


This should be in the owner's manual. I found the below on autozone.com, their repair help location:
An inertia switch is used as a safety device in the fuel system. The inertia switch is located in the cab, generally under the dashboard on the right side. It is designed to open the fuel pump power circuit in the event of a collision. The switch is reset by pushing each of 2 buttons on the switch simultaneously (some models use switches with only one reset button). The inertia switch should not be reset until the fuel system has been inspected for damage or leaks.
When the ignition switch is ON , it turns the EEC power relay ON . The EEC power relay provides power to the powertrain control module (PCM) and the control side of the fuel pump relay. Power for the fuel pump(s) is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flows through the fuel pump relay and inertia switch to the fuel pump(s). The fuel pump relay is controlled by the PCM.
When the ignition switch is turned ON , the fuel pump(s) will operate. If the ignition switch is not turned to the START position the PCM will shut the fuel pump(s) OFF after 1 second. The PCM will operate the fuel pump(s) operate the fuel pump(s) when the ignition switch is turn to START position to provide fuel while cranking.
After the engine starts, the PCM will continue to operate the fuel pump(s) unless the engine stops, drops below 120 rpm or the inertia switch is tripped.

Is there a fuse for the fuel pump 92 grand marquis


Hello fellow Grand Marquis owner...

Yes, there is a fuse, relay and an inertia shut-off that all affect power to the fuel pump.

The fuse for the fuel pump is in the power distribution box, under the hood. Fuse #8, a 20 amp fuse that also protects the electronic engine control relay. This fuse box is immediately behind the battery.

The fuel pump relay is immediately behind the power steering resevoir on the left side of the engine compartment. It's under a cover that houses three relays. Look for the words, 'FUEL PUMP RELAY'
on the plastic cover and carefully lift to check the relay, if necessary.

Check that the inertia switch didn't go off from a pothole or other jolt to the car. It's in the trunk, on the left side, above a yellow warning label with instructions. The reset button is pointing upward through a hole in the fuzzy gray trunk carpet material.

Good luck from Detroit, MI.

Wanted to no if there wAS a reset button after changin a 2005 cobalt fuel pump


GM does not have a reset button to reset the fuel system. The only manufacturer that I am aware of that does this is Ford. If the pump doesn't work than the first thing I would do is check for power at the pump. There should be two gray wires at the connector. The bigger one is power to the pump. If there is no power than check fuse and relays.

Fuel Pump isnt running. will not start. Its not the collision reset. Simply no elec going to the pump at all. Ran fine yesterday.


Fuel Pump Relay can cause this, so can a bad ground or a dead pump. I would also check the fuse for the Fuel Pump.

GM CARS DON'T USE A FUEL PUMP RESET BUTTON, THEY HAVE AN OIL PRESSURE CONTROLLED FUEL PUMP CUTOFF SWITCH ON THE ENGINE, IF THE CAR HAS NO OIL PRESSURE AND THE KEY WAS ON THE FUEL PUMP SHUTS OFF.
