Problems with 1996 Mercury Grand Marquis

Sometimes my Grand Marquis will just not start, although the lights, radio and all other electronic things are working. I have had the fuel pump and the computer replaced as this is what the mechanic told me was the problem. I am still having the same problem. when it does not start, I can take one of the wires loose and try to start. it will turn over almost every time, then I turn it off, plug the wire in and it will start right up and continue to do so for about a week or two and then I am back at the same place. Any suggestions

    We have always been able to pull wire #5 from the right coil to make it start. Then kill it, replace the wire and it will start again. However, this did not work last week. Now, I had a friend tell me that it is my relay that is bad. Which one....who knows! You can spend a mint replacing relays. the odd thing is that when you let it sit for about 20 minutes, it will start up again and runs great. i never have a problem with the car running - when it starts. I have been through what you are talking about, we replace the fuel pump and the fuel regulator. I have a new computer (did not help). i am just tired of throwing money away with all of these mechanics and am looking for a solution with someone that has had the same problem. As far as replacing the fuel pump, I had a mechanic do it since it is in the gas tank.

    Same deal with mine. It was just rolling over to 100k miles when starting problem began. Bought new battery, started fine. A week later, all the lights went on, not a crank or even a sound---didn't start. Dealership said it was a bearing in column shifter assembly. Replaced it. I took it home next time I tried to start it---nothing!. It's been in and out of the shop twice (towed in) and dealership cannot find anything wrong. It starts for them everytime, they say. Now they want to replace the starter, saying the bendix may be bad.

    I have a 2000 Mercury with similar condition. I checked the fuel injection manifold for pressure and its empty. I pulled vacuum on the fuel regulator to see if the supply line was pressurized but the regulator wasn't passing fuel and no response. I checked the fuel pump relay and measure an odd 6V on the output while the relay is not energized. This seems to indicate an open ground for pump while the PCM is sourcing power from its input. I pulled the back seat and verified the ground is connected (of course the wires could be broke inside the insulation I suppose). So I am looking for info on the fuel pump removal procedure.



    That's when I saw this post and am curious as to which wire you pulled off to get yours running - was it a spark plug wire or some other wire?

I used a scoket drive with a flex head and vicegrips.  Now I'm trying to find out what you have to do to get it out after that.

SOURCE: where are the spark plugs located on a 2000 Mercury Grand Marquis

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.

SOURCE: Overdrive light is flashing on my 1996 Mercury

That usually means the transmission is in "LIMP" mode... Just to get you home or to a Service Center of your choice (one that does transmissions).... When it O/D blinks the car will drive sluggish... it stays in second gear and does not shift.... just so you can LIMP somewhere...... a good price to rebuild this transmission is about 1500 dollars.... Good Luck

SOURCE: Do you have to take off the fuel tank to replace

Hello Friend:

Your 1st Soution to Reach in Between the Rea Axel, You Can Try that.

But i Personally Recommend you Take Loose the Straps so you can Make Sure you have a Good Veiw of the Fuel Pump Retaining Ring.And Make sure you Get it Replaced Right and Have a Good Seal on That Rubbed Gasket And can Tighten the Ring Good.Not Counting the Wiring that Goes to the Pump.

Hope this will help you. Please let me know by Voting for The Quality of my Solution.

Thanks For Using FIXYA From : d_hubbs

SOURCE: How to reset Check Engine

You can remove the NEG battery terminal for 10 minutes and it will clear. Or go to Autozone or Oreillys for a free scan, find out why it came on, then have them clear it with their scanner.

Is there a fuse for the entry pad on a 1996 Mercury Grand Marquis?


Fuse #8 on the interior fuse panel and 20amp on the engine compartment fuse box, but if either of these were blown you would have several other things not working, door locks from any switch, dash board wouldn't light up, cluster radio heater control and d o on.if all this is working, I would start my testing at the door pad.they get little cracks in them over time and water gets inside and corrodes the switch, pad, internally. .ive done a lot up hete on east coast. .

1996 grand marquis no start no gas out of fuel tank wont even reach fuel filter ???? what should i do ??


There is a switch in the trunk. It is usually on the drivers side. It is an Inertia switch and it has a button you press to reset it.

This Inertia switch is a safety item and sometimes they work when a trunklid slams or a door closes just the wrong way.

You could have blown a fuse although there is usually a reason for it. The owners manual shows the placement and size of the fuse. If you can not get the fuel pump to work, then most likely it is bad.

I hope it is only a matter of resetting the Inertia switch in the trunk.
