Ok I really need some help on this one. About a week ago my engine started acting up. It would take about 5 seconds of cranking to get it started, then I would have to hit the gas to keep it alive. Once I put it in drive and drove off it was fine, still great power and all. BTW I have a 96 SHO. SO Yesterday I am driving up a hill, I hit the gas, and nothing at all, power steering locks up, engine dies. I throw it in neutral and try to start it...nothing. I pull over, and jump out and open the hood. The smell of fuel is horrible. (Also note, I pulled a P0172 code, Bank 1 running rich) and an emissions code. So I try to get it started nothing. I smell fuel everwhere, I open up my air filter and waalaa, fuel sopping in the air filter. I look under the subframe on the ground, big puddle of fuel. Now I think it is a fuel pressure problem, I am not sure tho. I have had two mechanics concure with each other on the diagnosis. I call my mechanic he says, pull the vacuum line off of the FPR. I do, and gas shoots everywhere from the regulator. He says, "Thats your problem". No I went today to the ford dealership wehre I had my car towed, had a friend turn the ignition to the on position, and Fuel shot out at a high rate from the regulator. I already oredered the damn part, 70 bucks, and I think the regulator is supposed to do that. I knwo the FP itself delivers about 10 times more fuel than what the injectors need, so Is it the regulator or not??

BTW< I just had the cams welded, and I also checked the oil for fuel, and there wasn't any. Any help wopuld be much appreciated.

There is a diaphram inside the regulator that has ruptured. That is allowing raw fuel to go straight to the intake whenever there is engine vacuum.

Your mechanics are correct - the FPR has failed. This was a common failure on first generation Explorers if it makes you feel any better.

If that is the only problem, consider yourself fortunate.

BTW, more Gen III people would have seen this if posted in the Genn III forum. Maybe one of the mods will move it as apprpriate.
