Mustang GT will not start

Well, I was driving down the road the other day, traveling about 70 listening to the stereo and out of no where, I had no power. I still had stereo, brakes, all that. Had no gas and no power steering. I just filled up that day so its not out of gas. Any ideas? Ive replaced the fuel filter, you can still hear the fuel pump turn on when the key is turned to accessory mode. When you turn the key all the way it just turns over and over. Please tell me whats wrong with my baby.
IT DID fire and come on, but as soon as I hit the gas it cut out and when I let off it came back some but then shut off. Now when I try to start it up again it just turns over. Is it possible that it is flooded from all the previous attempts of starting it and seeing if the fuel pump turns on?

What are my next steps I should take?

Right, makes sence. I have a 1998 Ford Mustang GT with roughly 63,000 miles on an automatic transmission.

Lets go back to basics. First we want to insure you have a good spark to the plugs and they are all good.

Next you want to determine if you have fuel to the engine with the correct pressure. We want to isolate if it is the fuel pump or fuel pressure regualtor. The fuel pump is NOT supposed to run in the accessory position--ever.

Check theses things and get back with me but right now I suspect the fuel pump or fuel pump relay. Check it and let me know.

A lot of times cranking the engine over and over will wash the cyls down as well as kill the plugs with gasoline.

There are a lot of variables to consider but basics first. Good luck

Well. I checked the schrader valve to see if there was pressure and gas in the fuel rail and there was, so doesnt that rule out a fuel problem?

Not until you have verified fuel presure. It should be 35-42 pounds with key on engine off.

Have you pullled a plug wire to verify spark?

Fuel pressure is checked with a pressure gauge. You check it key on engine off, engine running and then pull the vacuum line to the regulator to see if the pressure increases. It is mostly a mechanics job because the Ford valve is a little smaller than a normal valve. Good luck
