I have a 92 Mustang GT with about 80,000 miles on it. I just got it at the end of last summer. The car is 100% stock with no mods. When I try to start it, hot or cold, it wont start unless I push the gas pedel all the way to the floor. Once it starts, it runs fine with no problems. I'v checked everything I know of. Have any of you guys had any similar problems or where could I look to fix it. Another note, I live in Wisconsin and it only started doing this when it got under about 50 degrees. When it was warmer out, it started fine.

When you turn the ignition to the on position listen to see if you can here the fuel pump running for about 10 seconds, it should be. Also you my have a bad o-ring on an injector or fuel rail.

actually, the fuel pump should run for ~3 seconds... However i do agree that it sounds like a really bady leaking injector

crank the car over without putting it in flood clear mode. when it doesnt start, pull the plugs out one at a time and see which one(s) are covered with fuel. You may want to start searching for a new set of 19# injectors

The fuel pump does cycle like normal. Would running some injector cleaner help or is that just a waste of money? Thanks for the help.

fuel injector cleaner wouldn't help a very possible leaking injector!
