Sure, the more the throttle and the longer its open the more gas is being injected so if the spark is not there it will spotter. I think you have nothing to loose with an ignition tune-up. It'll be more economical than taking it to a mechanic and still ending up with the same problem. You should change the fuel filter also it could be clogged and there is'nt enough fuel delivered at these speeds. You can also try a fuel injector cleaning solution the kind you pour in the gas tank. This might work for you.

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: Fuel issue on 2001 Grand Marquis

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

Mercury grand marquis wont stay cranked


Someone will need to check for spark to the plugs and fuel pressure when it fails to start. Could be a relay or several other components.

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).

I put a new fuel pump in and still wont start


ok if the fuel pump is energizing and you can hear it turn on then the pump is working fine and you probably have a restriction. i would replace the fuel filter. when you replace the pump did you replace the strainer on the pump? if not then thats where your problem lies. also could be the fuel pressure regulator also. there is a schrader port on the fuel rail try taking a pen and press down on the core to see if fuel squirts out. or connect a fuel pressure guage to the port and see if you have the right fuel pressure. it should run between 35 and 47 psi

Getting fuel wont start


If you can, have the computer scanned for active codes. Always check for fuel and spark. with fuel injection it isnt enough to know that the pump is running you need over 35 psi, line pressure. Let us know.

make sure to do a fuel pressure test and the presure should stay at 35 psi even after turning ingition off the pressure must to be at least 25 to 30 psi for a few minutes, if it goes to cero or close to it, after turning ignition on then you might need a neww fuel pump installed on it
