I have a 1995 Explorer that wont start after sitting for a while.
Usually I hear the fuel pump for a few seconds, when it goes off, it will start.
Now the pump stays on for 10 min, and it wont start while its on.
I have replaced the ECM and fuel pressure regulator.
The pump runs continuously as long as the key is turned forward, until it finally stops 10-15 minutes later. The engine will not fire until the pump stops. It cranks fine, but there is no injector pulse present until the fuel pump stops. The check engine light is on (as it should be)while the key is forward. It blinks once, when the pump stops. This & the lack of fuel pump noise tell me that the engine will fire.
After the pump stops the first time in the morning, it will operate normally throughout the day, provided there is not much time between uses. It seems that the problem exists only after sitting (and not being run) for an extended period (overnight or after work)
