If there is insufficient fuel pressure in the manifold to keep the injector working yes it will cause a problem as you describe. Have a fuel pressure test done and eliminate the pump and the fuel regulator .

SOURCE: fuel pump location 2001 pontiac grand am

The fuel pump is in the fuel tank.Sit in the car.....turn on the ignition switch to run.....listen very closely to the rear of the car...or have someone kneel down by the back wheel.....you should hear a "prime cycle"......the pump running for 2 or 3 seconds if the key was off for 15 seconds before trying this.If you hear silence you most likely need a fuel pump.Before pulling the tank down....check for power on the gray wire at the fuel tank connector just ahead of the rear axle under the car.Check for power with a test light that will last for 2 to 3 seconds as you turn on the key to run.Power means you really most likely need a pump.No power means you may need a fuse or a fuel pump relay.

SOURCE: 2000 grand marquis cruise control not working

Have seen this problem before. You need to look under dash at brake pedal and find a blue switch with plunger contacting pedal, disconnect connector and jump with a peice of wire and drive to see if cruise works and if it does replace deactivation switch this should get you going.

most cars have an oil pressure sensor that is tied into the fuel system that will shut off fuel pump if oil pressure is low. Ford is famous for having a yellow fuel pump cut off switch that activates in a collision - you need to locate and check this 1st

SOURCE: how can i change fuel filter in my grand marquis

you will need the proper Quick Disconnect tool, Look on the Frame rail for the filter, remove filter from the spring type retainer, remove the safety clips on the lines but not remove them completely, insert the disconnect tool & push into the fitting of the fuel line, push line & tool into eachother then pull filter away from line, if not done properly you will have a big problem putting the line back on

2000 mercury grand marquis starter turns over but car wont start its a 4.6 engine


Engine is not FIRING? But it turns over,right? Assuming this is so, I'd run the OBD II codes first.
Fuel pump operating? Can you hear it when you turn the key to `ON'?
If not,there's a fuel pump reset button,I believe in the trunk(safety switch in case of collision).

After putting gas in the car started running rough and is chockin


It wouldn't hurt to change the filter, but it sounds like you got a bad batch of gas, if it was running good before you got gas.
Get a bottle of dry gas and put it in the tank, if there is any water in the gas, that will clear it out, also it wouldn't hurt to put a bottle of fuel injector cleaner in the tank, I use that stuff all the time to keep the fuel system clean.
