Car Forum / Ford / Ford Mustang / April 2005Mustang Quits!
I have a 92 GT, starts fine and runs fine for about 5 to 8 minutes. Then it just quits, If it does refire you have to pump the gas to keep it running. I know its in the fuel system somewhere,but were? Thanks Dean. > I have a 92 GT, starts fine and runs fine for about 5 to 8 minutes.

Patrick '93 Cobra Start with replacing the fuel filter. If that does not help, then get a fuel pressure gauge and test fuel pressure at the schraeder valve on the fuel rail on the engine. if memory serves me right, its on the left hand side (you standing at front bumper looking at engine) front corner of the engine. 'schraeder' is the type of valve on your tire's valve stems. I think about 30 PSI is correct here, but double check in your haynes or chiltons manual. If you don't have the requisite pressure at the schraeder valve AND you've replaced the fuel filter, my guess is that your fuel pump is shot. You might also have a pinched fuel line (put a floor jack in the wrong place lately?). Your car is 13 years old, so its entirely possible that the pump is worn out. The pump is in the tank, so you have to drop the tank to replace it. Make sure you replace the fuel filter (again) after you change pumps - theres alot of crap that can get in the lines when you disconnect everything.

And don't forget to change the fuel filter while you're back there. And hopefully you have a close to empty tank as well. > Hell I'm on my third pump now (88GT) and it's making noises like its fixing > to fail yet again.

Man, you need to buy gas somewhere other than Wal-Mart! :-p Sam's club actually, it's not the gas it's the design, an in-tank fuel pump needs to be kept totally immersed in order to keep itself cool and properly lubricated. On a Mustang the silly thing starts to become exposed at a little less than 1/2 a tank. Popular Science magazine recommends never letting your tank go under 1/4 in order to extend the pump's life. Advice I'm obviously not following. > > Hell I'm on my third pump now (88GT) and it's making noises like its fixing > > to fail yet again.

Actually, When I moved, I changed from buying at the same Exxon that I had use since I was 14 and started buying at Albertsons. It was in about June. That year when it got cold my Mustang for the first time since 1989 started being cold natured in the morning. I switched again... But I remember reading that about in tank pumps and thinking yinkes. Then when I replaced my original pump I took it completely apart to see how it work. The realization was sobering. I wondered who was the first guy that dropped a running 12V electrical motor into a bucket of gasoline to see what happened.

LOL what a tard gas does not burn hurc ast The design 'kind of' makes sense on paper, but it just doesn't seem right somehow. I wonder if the engineer took into account what would happen if the tank were to be punctured and the pump were to remain running. (Make believe there are no external safeguards.) > > Sam's club actually, it's not the gas it's the design, an in-tank fuel pump > > needs to be kept totally immersed in order to keep itself cool and properly [quoted text clipped - 12 lines] > first guy that dropped a running 12V electrical motor into a bucket of > gasoline to see what happened.
