Question about 1996 Mercury Grand Marquis

1 Answer

My 1996 mercury grand marquis starts and runs good, good power, has 200,000 miles on it. When I fill it up and drive it, it dies and starts right back up. I think it is the fuel pump. I have not checked the fuel pressure this is just my guess. What is happening? LA

    Do you have a service engine light on?

  • leearent Jun 02, 2010

    I have a check engine light on, however I have had this problem before the light came on. I have tried: new idle air motor, a new gas cap (not a motorcraft cap) new plugs and wires, cleaned the trottle plate. The fuel filter has about 20,000 miles on it.

    Thank you for your opinions. I can get access to a snap on computer with the different chips for different cars and read the trouble codes. I will also check the fuel pressure and replace the fuel filter.

You might have a bad gas cap. I would also change the fuel filter, I did a fuel filter on the same type of vehicle and the gas coming out of it looked like black ink, it was so dirty.

    You are about due for another fuel filter. I would check the fuel pressure at the test fitting on the fuel rail. I would see what code is associated with the check engine light.

    From the way you discribe it, it dies only after you just fill it up and just the once and then restarts?
    I would be curious to see what trouble codes are in your computer. Even though it was on before, it may have stored more problems since it first came on.
    A fuel pump is more likely to asct up when you are low on not not when its full. What is likely and the only thing that comes to mind is your fuel system is not "breathing" right. It is a .
    closed system and gets vented through a carbon canister and is control by the computer.
    Most parts stores will read your computer codes and give you the results for free since your car has an OBD2 emissions
    system. I am hoping this will give us more info on the problem.

    Checked trouble codes/check engine light. P-136 is the only code in the memory and active.

it is on the fender near the battery and is also referred to as the starter solenoid (if you follow the large wire from the positive terminal of the battery at the other end will be your relay/solenoid)
hope this helps!

SOURCE: rear shocks on a 1996 Mercury Grand Marquis

Raise car under frame then put jack under axle before removing the shock.
Can use locking pliers to hold the shaft from turning (may have to cut away dust boots). Top nuts are accessed and can be seen from the wheel wells or from the gap between the trunk and mount frame (can't see nut from this angle). Take care with fuel lines near the driver side nut.
Preventing shafts from turning on new shocks will be tough. Make sure you have a proper tool to fit top of shaft with enough room between top of shaft and trunk (gap decreases as the nut is tightened) so the tool can be removed.

Where is the starter located on a 1996 mercury grand marquis?

It should be located on the same side as your battery. Follow the positive wire from the battery and it should run to the starter. Hope this helped and good luck.

I would use 10W40 in the 96 and 5W20 or 30 in the 2002.

For the 96 with sluggishness, you need to gently clean the MAF sensor wires with carb cleaner and a toothbrush. It is in the air intake tube. After cleaning, disconnect the battery for 1/2 hour, then reconnect so the computer can relearn the clean sensor. Drive for 10 miles, it will run rough until it relearns.

Section 03-14: Engine Controls, Electronic 1996 Town Car, Crown Victoria, Grand Marquis Workshop Manual
DESCRIPTION AND OPERATION Mass Air Flow (MAF) Sensor The mass air flow sensor (MAF sensor) (12B579):
  • is mounted on the corner of the engine air cleaner (ACL) (9600).
  • uses a hot wire sensing element to measure the amount of air entering the engine; air passing over the hot wire causes it to cool.
  • sends out an analog voltage signal to the PCM (12A650) to determine the intake air mass. The PCM will then calculate the required fuel injector pulse width to provide the desired air/fuel ratio.
The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly.

95 Grand Marquis loses power between 45mph - 60mph

Mine was doing the same thing. I took it to one place and they charged me $107.00 for a fuel injection cleaning. That didn't do a thing. I then took it to a backyard mechanic and it turned out to be a bad spark plug. It has been running great ever since. Good luck.
