Hello, have a rebuilt engine in my 2000 gt. The car sat for over a year so I put in a new engine, a new fuel tank from the bad gas sludge and a new fuel pump. The car ran like a pony should until after about a 30 min drive it would shut down and leave me stranded. After about 30 min cool down the car would fire up and off I go until the pumps over heated again. Since the fuel pump was after markets I bought from rock auto. I pulled it and got a replacement and again left me stranded after about 30 min of driving. When I drove the car it didn't lack any power.
I then got a Ford motor sports fuel pump from rock auto. Now the car will run all day long. I can rev it as high as I want. But when I try to drive it, it bogs down like I hit a brick wall and jerks badly. I can't go 5mph in it now.
I've checked for air leaks. I've changed coils, fuel injectors, maf sensor, fuel pump driver module, fuel tanks, purge valves, EGR valve, 2 computers programed by the dealership And still won't drive.
I hooked up my data logger a few yrs back and it shows that when I mash the gas to the floor, my air goes up and my fuel shuts down. When I released the pedal, my air drops to normal and fuel pressure comes back up.
This is a beautiful gt that's been sitting for about 5 yrs. I need to fix it or crush it. Any suggestions on where to look for a solution or any recommendations on a mustang shop in Ga that can fix it? I leaning towards fuel issues because the aftermarket pumps ran the car until the pumps got hot without power loss or issue. Where as the Ford pump never shuts off but stallsnthe car under throttle.
