89 F250 460 Won't start on first try
Just bought an 89 f250 with a 460. It wouldn't start on the first try when cold. The starter turns and its like it hits on one cylinder and then dies. You think it's gonna fire right up because the starter doesn't have to spin very long. I've changed plugs, wires, cap, rotor, fuel filter, air filter, cleaned the throttle body, pcv system and used in-tank fuel system cleaner. It still does the same thing. Sometimes it does it twice, when it fire up its runs fine. I've held the key in the on position for a few seconds to ensure fuel pressure is up, but that makes no difference. Any Ideas? Old gas? Dirty injectors?
