Question about 1989 Mercury Cougar

1 Answer

Cougar fuel pump relay

No fuel pressure at all. Pump makes no sound when key is on. I tried resetting the Fuel Pump reset button in the trunk, but it was not tripped. I have heard that a CCRM module would prevent power to the pump. How would I check that module? This is on a 1989 XR7 Cougar, 3.8 Supercharged, five speed car.

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 Cougar, XR7, Supercharged-- I have zero fuel pressure. Is it most likely a relay, a fuse, or the fuel pump?


This sounds like the Inertia switch is tripped. This switch is either in the trunk or behind one of the kick panels. This is a resettable switch that cuts power to the fuelpump in a collision. Often a bump of the correct frequency will trip this.

You also have a fuelpump relay in one of the Powerboxes. The sequence is such that power goes to the relay and the wire from the relay goes rearward to the inertia sensor in the trunk(Or kickpanels) which acts like a breaker and then the power goes to the pump.

My mercury cougar 2.5L 2002 dont start look like no fuel go to the engine. before check the fuel pump is any fuse o relay can I check?


Check a part called an Inertia switch. Do a Web search for photos and location which is usually in the trunk or in the front by the floor kickpanels. This part has a reset button on it and when pressed it will reconnect the fuelpump power.

My car wont strat? my wife run it out of gas. now it wont strat and its got a 1/4. of gas in it.


It might just need primed Josh. Turn the key on for 10 seconds, and off for 10 seconds. Do this about 8-10 times. If this doesn't work, check your fuel pump fuse/relay or reset button if you have one.

Fuel Pump is not activating when ignition switch is turned, I can hear the clicks in the relay box. Does this mean the relay went bad?


Not usually, when you hear clicks it means the relay is switching. Its probably the fuel pump that needs attention.

Where is the fuel pump reset button on a 96 grand am 2.4


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.
