Question about 1983 Mercury Grand Marquis

2 Answers


I have repace the spark plugs and fuel filter on my dad's 1998 grand marquis. The car ran about 2.5 months before but has never been started since I started replacing the spark plugs and fuel filter. It does crank over but I have zero fuel pressure. I do not hear a noise when I turn the key on. Not a 5 second hum or nothing. When replacing the fuel filter I had my father turn the key in the ON postion mutilple times and NO gas came out - at all! After checking the power going to the pump, I believe that the pump has froze since he last used the car last(about 4 or more months). MY QUESTION: Is it nessary to drop the fuel tank when replacing the fuel pump? I can see the fuel pump assembly right behind the rear axle. It looks pretty accessible if I jack and support the car or have a car lift. Is this true?? Please let me know. Thanks.

Yes you can replace the fuel pump on a 1998-2002 without removing the gas tank you just have to remove a few exaust hangers to make just enough room to get the sending unit out on cars without dual exaust otherwise it is very simple.

So you have power there, why not try a little whap with rubber hammer near it while key on to see if it will do anything. I;d try it just to see if it will come back to life.

Pull a plug wire and see if it is getting spark. If yes then hook a guage to the fuel shrader valve and check the fuel pressure. Just because you replaced the fuel pump already does not mean it didn't go bad.

Car runs but when you accelerate the car sputters and shakes does that mean replace the spark plugs and wires

Possibly, but other things can cause the same symptoms. If the check engine light is on, a scanner read of the computer will give you better clues that 'hip shooting' parts replacement can do. Possible things to look for--weak fuel pump, plugged fuel filter, water in the fuel, spark plugs and wiring, O2 sensor, and the list goes on.

you can try just resetting the fuel pump switch located in the car

the switch is originally in the car for in case of an accident, however, if changed, chances are you also have to reset it
