SOURCE: Engine will crank, but will not start.

I just had this same problem on my 96 Explorer XLT. Very random when it would do it, sometimes everyday for a week or nothing for 6 months. What I found was that when this happened, when I turned the key to the on position without starting the vehicle. That the check engine light should come on and if it doesn't, that means the the computer isn't powering up. What I had to do was leave the key in the on position and pop the hood, and on the passenger side of the engine compartment, there is a power distribution block, in there is a relay for the EEC Power Relay. Now with the key on I wiggled this relay and you can hear systems under the hood kick in. Relays turning on, etc nothing actually starting to scare you though. But this lets you know that the computer is alive and running. You should now be able to turn the key to the start position and the vehicle should no crank over, but now fire and run. It took me quite a while to figure this out because it was so intermittent. In the end, I replaced the relay for the EEC Power and everything has been fine since. When the new relay was in there I could not replicate this fault as I could with the bad relay. Hope this helps you.

SOURCE: How to replace '96 Ford Explorer driver side exterior door handle

You will need to remove the door panel to gain access to the handle. Roll the window up or down as needed to get to the nuts that attach the handle to the door. You will also need to remove a rod the goes to the door lock. You will see the rod after the door panel is removed. Good luck.

SOURCE: On my 1998 Ford Explorer

Normally, you would insert the key in
the driver's door, turn left, then right
to disarm and reset it.
You can turn off the anti-theft system in a Ford Explorer by starting the vehicle with your existing factory key.

If yours is malfunctioning,
you can disable it for good by doing the following:The FACTORY ALARM DISARM WIRE IS

dk. green/purple driver's kick panel.

Once Located, splice into this wire with
a similar gauge wire, and put it to
a solid chassis ground. This terminates
the OEM alarm functions entirely.

P2195 CODE ON 2003 FORD EXPLORER SPORT TRAC 4.O SOHC. I CHANGED OUT ALL THREE OXYGEN SENSORS, AS ADVISED, AND STILL COMING UP WITH P0171, P0174, AND NOW P2195. HAVE ALSO CHECKED ELECTRICAL CONNECTIONS,...


Hello,
Very common concern with the Explorer, Explorer Sport Trac and Ranger with the 4.0l SOHC engine! The upper and lower intake manifold gaskets fail, causing vacuum leaks..It can be Extremely difficult to detect these leaks, because they only leak intermittently (usually in the AM after a cold soak)... As the engine warms up they seal back up! Sometimes the vehicle will idle rough, surge or stall after initial start up, then the symptoms will clear after it gets to operating temperature... Usually there will be no driveability symptoms at all, except the engine light coming on and setting lean codes.. The gaskets have been redesigned to correct this concern..
