My wife's SUV decided to die 2 weeks ago in a turn lane. It has had some rough idling issues up till that point, but when it died, that was it. Couldn't turn the engine over, eded up killing the battery. Jump didn't help. Nada.

I have just replaced the fuel pump and fuel filter today, but the same problem persists. When pressing the fuel line gauge under the hood (can't remember what that thing is called, same thing on your bike tire), only a little bit of fuel comes out, you can tell there isn't much pressure. The fuel pump does come on when the ignition is turned.

I'm losing hope that I'll be able to figure this out myself. What am I missing? Could there be a blockage in the fuel line or maybe the fuel regulator is toast?

Any help/ideas of stuff to try is DEEPLY appreciated.

Usually the fuel pressure regulator makes them run rich. Have someone turn the key to ignition while you hold the shrader valve in to see if you get pressure at that time. Where did you get the pump? We got one from Autozone that wouldn't pump. That can happen from any place. Recheck the lines to make sure you didn't pinch one. Been there, done that.

I had someone hold the shrader valve today while I turned the key, it only spirts out a small bit. I got the pump from autozone. I'll be kinda PO'd if the pump is faulty. All lines seem to be good, nothing seems pinched and no leaks anywhere.

You could get something to catch the fuel, take the fuel filter off and see what fuel comes out there with turning the key to on.

Hmm... I may try that tomorrow. Thanks!

Okay, removed the fuel filter, turned the key to prime, fuel is coming out. When attempting to start the engine, there is a continuous stream of fuel, so the pump seems to be good. I put a brand new fuel filter in, now fuel is shooting out of the shraeder valve with ease. The engine is still not starting however.

I have bled the shraeder valve numerous times to ensure there is no air in the line, but still no dice.

Someone mentioned the fuel regulator. Where can I find this on the explorer?

Bert

Usually the pressure regulator give to much fuel pressure. Do you have spark at the plugs? You can take a wire off one plug, put another spark plug in it and crank the engine. The base has to be grounded. The IAC can also cause a problem. If you spray starting fluid in the intake, crank it, and it starts for a short time, you know it's getting spark and not fuel.

I did check to see there was spark, but only two out of the 6. I will try the fuel thing later.

If you find that you have good fuel delivery after all the diagnostic checks then maybe check out your coil pack and everything associated with it.
