I have a 2003 Ford Explorer XLT. I drove to work this morning without any issues and no sign of any problems. When I got off of work, it wouldn't start. It's cranking but not turning over. I tried the fuel pump reset without success. When I turn the ignition to on, I can hear the fuel pump turn on so I don't think that's the problem. Any advice?

 

What does the anti theft light do when attempting to start the vehicle? If possible , try one of the other coded keys.

 

It's not doing anything out of the ordinary. I only have one key.

 

Next step is to check all the fuses.

 

Even though the pump runs, I'd check pressure/volume at the rail. As well as spark, but pump fails are fairly common. Prove out what it not (or is) helps to move ahead. OE pump still.?, how many miles on the clock?

You might try a 'Short shot' of ether/ starting fluid into the intake, if it fires, then look towards fuel delivery and/or power distribution issues..
