Explorer not starting...

[saltydogrichman]

Runs great, never had this problem. Drove car yesterday...today the engine turns and turns but never fires. Has anyone experience this before? I have looked over all of the obvious...next is tow truck to mechanics. Help! Thanks.

A coulple things you can check:

1) Fuel shut off
2) IAC
3) MAF

If the latter two it would probably still start before it dies.

another thing that it could be is the crank shaft positioning sensor. I had the same thing happen to me and we had to have it towed. It just died while I was driving one day and would crank forever but not start.

Mine did that, then the theft light came on, did some trouble shooting, my friend started it got it going again and shut it off right after it started and it wouldn't work again. PCM went down the crapper. Free fix though, just had to buy a second key and pay for part of towing it (insurance covered half).

Do you hear the fuel pump when you turn the key to "on"? If not, check the relay in the box under the hood.

I had a no start situation several years ago; turned out to be a bad O2 sensor.

Take a look at the thread at http://www.explorerforum.com/forums/showthread.php?t=34619&highlight=alarm+system

Good luck.....

The first thing you need to determine is if this is an electrical/sensor problem or a fuel delivery problem. If you can hear your fuel pump kick on and you get good pressure on the fuel rail, its probably an electrical/sensor problem.
