Detail: Have a 1998 Ford Mustang. Took the battery out for the winter (on charger all winter). Now we have reinstalled the battery - it turns over good BUT will not start. Could it be a computer problem in the car or maybe the electric fuel pump? Any ideas?
Solution: Yes, reset fuel reset switch in truck of car. There is a fuse for fuel pump in engine bay. Lightly grease ignition key and work into ignition switch. A chipped key needs to be recognized by the anti-theft device built into your car. A worn key or dirty ignition has less contact and signal is not sent to the anti-thief device that unlocks the spark to the plugs (powering up). , Have you checked for spark at the plugs and the fuel pressure ? Can you hear the pump run for 3 seconds when you turn the key on ? , Hi, A 6ya expert can help you resolve that issue over the phone in a minute or two.

Good luck Davelee , on the mustangs i have the switch in just inside the rear hatch on the right side a yellow button you may have to remove a small cover to see it , So what you saying is it's hard to start cold right? Something in computer system not allowing excess fuel to injectors when cold. Probably sensor Get auto electrician to sort it out otherwise you end up replacing things that there is nothing wrong with They got the right gear , it's your upper intake manifold gasket. it has a crack in it and needs to be replaced. your getting to much air and not enough gas. mine did the same thing.
