Default engine cranks strong but takes a long time to start

The engine cranks over for a good long time before it starts and runs. It will run fine once it gets going. It has new plugs, wires, fuel filter, and air filter. I have not checked the pressure in the lines, but am hesitant to think fuel since it runs strong once it going. Any real ideas would be appreciated.

It is a 3.8L and there is no check engine light and there are no problems with the vehicle once it starts. It makes no difference if its hot or cold start it wont start either. It runs fine if you can get it started.

Very well could be or the fuel is drainning back into the tank. Which means the pump is not holding any fuel pressure after shutting off the key.

Before trying to start it, turn the key to the on position for a few seconds. If this is a case of the fuel draining back past the check valve, this will let the pump build pressure back up. If it starts normally, the pump assembly is your problem. If the problem were a leaking injector, you would get black smoke on startup which you didn't mention.

Static fuel pressure is 35psi = car engine off or at rest pressure.


53psi to 58tpsi effective pressure engine running idle with load it should stay in that range.

What year and model,, engine liter ?
