About 3 months ago, I had a problem with the Explorer starting. At that time, it would crank, but not catch. I replaced the fuel pump relay and the problem went away.
Now it cranks, catches, and then immediately dies. Time after time. I tried pumping the gas, not pumping the gas... And I've switched around the relays.
All ideas and suggestions appreciated....
Does it stay running with your foot on the gas? If it does, then you could have a problem with the IAC valve.
OK, I was able to start it by keeping the gas going, but when I take my foot off the gas it idles down, gets to the point where it is running rough, then dies. Does that sound like an IAC valve? What is the IAC, where is it located and can I easily replace it myself? Thanks!
I'm not sure where it is on the OHV V6, since I have the SOHC, but it should be a cylindrical looking object that is on the intake manifold, has electrical wires. On my engine it is directly on top of the intake manifold under the plastic "SOHC" shroud. It could be in the same location on your engine. Maybe someone with the OHV can help in this NG. In any event, they usually get dirty preventing them from working properly. Just remove it,clean out the valve with a solvent like WD 40, then put it back and it should work. If it still does not work, then maybe its time for a new one.
OK, did some hunting on the net and found a picture of what the IAC looked like. The IAC on a 4.0 '96 is on the drivers side of the intake, no need to remove any covers to get at it. I replaced it and now it is running fine. Thanks so much for the advice. This is a great group!!! The part was $43 at Advance Auto Parts.
