Please help. I have a 98 Mustang GT and it runs great but every once in a while it wont start. I would drive to the bank and the car would run great then i would come back 5 minutes later and the car would crank but will not start. I can hear the fuel pump working and the car is getting fuel. What could the problem be. please help i have alot of plans for my stang but cant get started until i fix this problem. Please Help

 

mine does this occcasionally--i have a few ideas of what it could be--possibly cuz my o2 sensors are toast and i have a o/r x pipe could be runnin a lil rich and somtimes they run lean (ive heard when o2 sensors are bad they make the computer tell the injectors to run at WOT or somthin but have also heard otherwise so im no tto sure) so when this happens to me i end up crankin is for a sec then while crankin it give the gas pedal a quick push and it fires right up. does your check engine light come on.?

 

check your battery because mine used to do that until i got a new one.

 

battery--only time the battery needs replacing is when it goes dead and wont hold a charge--i cant really see why that would be the prob.

 

it comes on when i try to start it. mine wont start if i give it gas but i can hear the pump working. then i let it cool down and come back in 20 minutes and it starts right up. Could it be a bad code.

 

check you iac
