did you do a fuel pressure test? if you havent do it its cheep an at least you can elimanate that. if thats not an issue, then there is only two other things crank sensor, and if there is one cam sensor.

sounds like fuel pump pressure. I had the same thing happen to me in a Lincoln mark VII and the electrical connection was shorting out in the fuel pump. I changed the fuel pump..Returned under warranty) put the new one on with filter and had no problem with it.

The fuel pump should be in the 20s. Also it could be losing presure slowly. Leave the fuel pump pressure gage on for at least 2 to 3 hours to see if it is losing pressure - It's a start

Why does my 2004 Ford Taurus start but wont stay running if I let off of the gas or try to put it in gear?


I'd be checking the throttle linkage stop on the throttle body/carb. Sounds like the throttle plates are closing off completely when you let off the pedal. Throtlle adjustment screw may have just backed out also.

It starts and idles, but if the gas pedal suddenly push to full throdle the engine dies, and when it is put into gear the engine dies


sounds like a fuel feed problem check your fuel pump and your fuel lines.best way is to connect a line from a gas can directly to the fuel pump and put the line from your tank into the can to prevent spillage.then try to start and throttle engine. if it dies that means there could be an in line filter or the pump is bad.if it works then run the hose from the tank to the pump if it doesnt work then its the pump and filter in the tank. if it works then clean the lines between the tank and the pump or engine.

My jeep will not start all of a sudden. When gas


Check the fuel filter, and i would suggest replaceing the fuel in the tank. It only takes about a month for gas to start to deterioate and if it sat that ling there is probally some junk in the tank. witch probally caused the fuel filter to plug up.
