Hi everyone!

Two days ago, my Explorer was running fine, all of a sudden, it won't start. It cranks, battery is brand new, terminals are clean also has new starter relay and gas tank is full. I'll appreciate any advise you could give me. Thanks.

 

Hi folks!

After checking ignition and wiring, sparks and all related parts, still cranked but did not start. Well, read on other forum about the "Crank Position Sensor", located on front of engine, just behind lowest pulley (crank). It was oily and dirty and had corroded contacts, so I unpluged connector and cleaned it off with WD-40 put it back on, and Explorer started at first crank. It's easy to do if you take off the right front wheel and reach sensor behind the lower pulley. It's a two wire plug with retainer clip (don't loose it) that you can remove with a flat tip screwdriver.

This was the third time the Explorer fail to start and in two previous occations I took it to Western Auto, but afer a year or so it went back to doing the same thing. To prevent it from doing it again I'll have to stop the oil leakage. That's my next project. By the way, my two trips to Western Auto cost me $1,200 and didn't fix the problem. Yesterday I spent less than $2 on can of WD-40 and SUV is running once again. Hope this info would help.

 

Thanks Tony, you didn't say you didn't have spark a plugs are not.
