Hi,
whilst i am not familiar with the actual car i would say...
if it cuts out immediately then its electrical...check coil, ignition amplifier etc.
If the car cuts slowly by losing power, spluttering etc it will be fuel related....fuel pump, fuel pump relay, fuel filter.
Does the car restart immediately or do you have to leave it for a while?
what happens just prior to the vehicle shutting down?

SOURCE: I have a 1994 Gran Marquis. Fuel lines are rotting and leaking

Just get a piece of the rotting fuel line so that you will be assured of getting the right size. Take it to a shop that sells car accessories, and ask them for enough to do your car. Also get new clamps. Start at the fuel tank, undo the clamp, pull off the old hose , put on the new one, do up the new clamp, and then just follow the old hose along, replacing it with the new one as you go. At the far end. do the same... undo the old clamp, put the new hose and clamp on. But I forgot to tell you about the fuel filter. Replace this while you are doing this job.

SOURCE: my 2000 gran marquis has a miss and then sometimes

Drive it to Autozone or Oreillys for a free scan. If your car has a problem causing stalling, you should be getting a "check engine" light. The codes that come from this light will tell the sparkplug that is bad and other things.

I drove a similar car for 165,000 miles and it was going strong when I sold it. While the engine is running take a spray bottle of water and spray around the intake gasket and Airhorn gasket. A bad gasket will change the RPM when water is drawn in. If no luck, sometimes the air chamber under the Airhorn can soot up and as it feeds the EGR passage there can be carbon on the EGR valve. The Airhorn only has 8 bolts and a gasket.

You may find all you need to know with the free scan. Good luck with your car.

SOURCE: i have 2008 grand marquis,

Hello, I see you have a 2008 model. The car came with a 3 year, 36,000 mile Warranty and still may be covered. The powertrain has a longer Warranty and yours seems okay, because the engine runs and the car is driveable.

You have a large connector which goes through the Firewall. The Firewall is the metal part of the cabin that separates the engine bay from the passenger section. You need to look at the connector and the Powerbox which contains the Relays for everything in the car.

First clean the Battery terminals and tighten them and try to use the car. If this does not help you want to disconnect the NEG terminal at the Battery and then unscrew the retaining bolt on the connector going through the Firewall. Pull the connector apart and spray it with WD40 while checking for corrosion on the connector. Carefully reconnect the 2 sections and reinstall the retaining bolt.

Open your Powerbox, look for traces of green corrosion. Spray green corrosion off with Electronics cleaner. Your problem is different than most because you are losing too much to come from one Relay. Check your Grounding wires and straps. These would be metal straps with no plastic covering or ordinary wires.

Your problem is likely a Ground strap from the engine to the body. The straps may be from the back of the motor to the body. Since the motor sits on rubber mounts the motor can be grounded and run, while the body sits isolated. Your fuelpump is probably grounded to the frame so it continues to work, but everything attached to the body does not.

This means your A/C, interior controls, and such are using the body to complete the circuit. Some times it is easier just to add a groundstrap to the body instead of looking for the factory strap.

I hope you find my solution very helpful in eliminating your electric problem.

SOURCE: WHY CAN'T I SHIFT MY 1997 GRAND MARQUIS OUT OF PARK AND INTO ANY GEAR?

You may have a faulty Break-light switch. If the switch is bad, then it will behave as if you have no breaks afa the shift-lever is concerned.

What's making my 96 corolla shut off while driving down the road or waiting on a light, and then doesn't want to restart when before it would?


The airflow meter in the throttle body needs to be cleaned. There is a special spray cleaner for this. WARNING: Do not use any other kind of cleaner for this or severe damage to the airflow meter will happen.

1997 gran marquis will shut done while driving


The biggest suspect I can think of is the ignition switch, as it also controls the electrical as well as the engine. If it happens again then turn your lights on (manually) and check if the headlights are on. If they are then there's a good chance it's ignition related. Check all fuses and make sure the fuse box itself is well grounded if the headlights do not come on. Make sure all battery connections are clean and tight. See if there is a engine code to give a greater clue.

Why do my 93 grand Marquis lose power and cut off when I put the car in drive


Do this service.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

I have a 1996 Lincoln Town car and while I was driving it shut off. I stared the car and it turned on but another 10 minutes later it shut off again. Could it be a fuel pump problem? Please help.


No its never the fuel pump, ever its always, the 8 dollat fuel filter that has so much dirt in it at 100,000 miles its like puring mud into a cup, or if this model has over 140,000 miles its possible the cat is ****, You can tho check that problem by disconnecting the rear muffler if possible if it runs better great. But you can also notice that a cat is blocked by starting it, when a cat gets blocked it takes more revolutions for the car to start. I would say its that cat, if you start it, then as soon as you put it in gear it would have no power, or it has power but shuts off, and you can restart it reletivly soon like a couple mins, Fuel filter you will just not be able to turn it on for the rest of the day.

96 F 150 5.0l stalls out. possibley heat related. wont restart right away. 2x have gotten restarted after 10 min. both times on highway. seems like ign. cant troubleshoot since it restarts. driving me...


The coil wire slide on type ( not Bolt on ) have a tendansy to expand if they get to hot, thus causing an open in your ignition system and shutting down your engine. much the same as driving down the highway and sudenly turning off your key.After a period of cool down you turn the key and the motor firers up right away because the coil cap has had a chance to cool down as well and cuntract to its original shape ounce again and is ounce again making proper contact,untill it gets to hot again and then the same thing will happen.Solution replace the coil half cap and wires to it.

Car quit and wont restart


It could be a any or a combination of failing components. If you haven't changed the fule filter recently (say within the past 20,000 miles) I'd change it first. Next. check the fuel pressure at the service port near the injectors to ensure you're getting the right fuel pressure to the injectors.
