Engine Performance problem
1984 Ford Thunderbird V8 Two Wheel Drive Automatic 114000 miles
1984 ford tbird ELAN 5.0, digital dash. The car runs like it has a bad fuel pump. Sometimes it runs ok, can never punch the pedal for it trys to stalls, runs rough, sometimes it starts great, sometimes very difficult. Sometimes dies while driving, or idling, burns lots of fuel, smells lots of gas, passes emissions.
Fuel filter was very dirty, I took to sun devil auto in Glendale AZ, was told that the low pressure was too low, and high pressure wasn't right, when they ran an engine diagnostic. I have done some studying and it seems that there are a few things other than the fuel pump could cause all these problems too. I read that and was told that the fuel tank must be removed. I went to www. Automd. Com and it says to get access by removing the rear seat. Do you know if I can get to it through the rear seat? And do you know of any other things, like a sensor, could be the problem? I got the impression that the engine diagnostic was a tool used to help diagnose the fuel pump, but that it wasn't 100% like when a diagnostic tells you that a sensor is bad with a code in newer cars. I want to fix but can't change every part it may be either. I really must know if you know if from the info I provided, if it is the fuel pump or something else. I couldn't get a straight answer from the shop who ran the diagnositc, just a guess that they were comfortable. I read in my research that this could be caused from other things. The car has had other problems for years as I have fixed them but hasn't run right for a few years, yet I only put about 500 miles a yr on the car. Hope you can help on this. I am trying to find an answer before spending money on unneeded repairs, and still have the same problem. Thanks.
have the same problem?
