My f 150 went through a car wash today, it sprayed underneth and then acted like it wasn't getting fuel. after several stop and go 100 yards it ran fine like no issues for about 10 miles. on a down hill slope it died and there she sets. towed it home and if you let it sit for a few minutes it will start but after a minute or two skips and bucks then will die if any gas is given.. fuel pump shot or is it a simple don't wet the bottom of the truck?? thanks
Sounds like you have a faulty Crankshaft sensor. Ford Part Number: 1W7Z6C315AB
It's simple to change but it takes about 3 hours to do because there's
just no room to work in that area. Your going to have to take the ac compressor off
(3 bolts) then take the 1 bolt out of the sensor, pull it out and
replace it.
Before you go and repalce the Crankshaft sensor, inspect the wire leads and look for any indication of loose or damaged connections or to the wire leads after you have your F150 scanned for any DTC codes.
Auto Zone or Parts Source scan ECM for the DTC codes free of charge and can give you the step by step instructions to address the issues.
Good luck and thank you for using Fixya.
