How to replace the fuel pump on a 1989 cadillac sevelle

There is another ignition module in your distributor that should have been changed when you were doing tune up. Try that first, then you can check fuel pressure to see if pump OK.
Another problem with these cars, was the catalytic converter plugging up.

TO replace the fuel pump, remove the gas tank. When replacing the fuel pump also replace the strainer on the bottom of the pump and replace the fuel filter.

Hello, The fuel pump is inside the gas tank. Remove the exhaust, Disconnect and remove all hoses and lines, also disconnect all electrical wires, remove 4 bolts from straps holding tank. Drop tank down. Remove lines and hoses from top of fuel pump module, remove lock ring, pull fuel pump module, turn unit as necessary so you don't destroy the fuel level sender. Hope this helps

91 Sevelle is operated using an electric fuel pump that is located inside of the fuel tank. Either the pump needs to be replaced, or, you have other problems and the computer is telling the fuel pump not to turn on.

I would suggest that you test the voltage going to the pump as well as the pressure on the lines using a fuel pump tester made for a Fuel Injected Vehicle.

If you attempt to spray a small amount of carb cleaner or WD40 into the throttle body and it tries to start when you crank it, you need a new fuel pump. You can spray a small amount of gasoline into the throttle body, reinstall the intake hose & try to start, sometimes the car will run until the fumes are gone. Use caution to prevent fires due to fuel getting onto areas other than inside the iintake/throttle body. Vent until fumes are gone if you accidently spill fuel to prevent possible fire caused by backfiring.

The fuel tank has to be removed to remove the fuel pump assembly, pumps are available as OEM or aftermarket pumps alone, or complete pump assembly. It is easier for those inexperienced to replace the entire assembly.

Good luck.

just the fuel pump

Fords have the reset switch option only. Relays are mounted on the firewall

the fuel pump is inside the tank. did the distributor cap get wet when you were installing the thermostat? check to see if the wires are pluged into the distributor cap well. if you use a fuel pressure gage you will be able to determine if the fuel pump is working.

this happen with my 93 ,if the car cranks,it's your gas presser regulator. it's on the top of the engine ,right side of carb.
