Does it have spark?
I ll be on here all day. Check the RPM signal during the no start.
The RPMs do not change on the scan tool while cranking. I don't know about spark yet as I ame here by myself and cannot be in two places at once. I realize I can jump across the solenoid but I don't have enough hands to make everything happen all at once. I will have help here soon so I will check spark then. Located the crank sensor and see that the compressor needs moved out of the way. ...... Just verified no spark.......Ok, went back outside and heated the area around the ckps with a heat gun, cranked for 10 sec and nothing. Kicked around for a few minuites, cranked again and it coughed, fired and went. Kinda pointing to the ckps. could be coincidence?
Yeah, I think it was just a coincidence. Try unplugging it and plugging it back in and see if it starts. I've had to replace the connectors on them before. I've also had to overlay the wires to the computer. Seems like it is always the wiring. It is possible the sensor could be bad also. I get my harnesses at the junk yard for over laying the wiring. All the f150 harnesses are pretty much the same. Might want to give them a call and see if they have a harness connector you can buy. Not sure if motorcraft offers a replacement connector. You can check on motorcraft.com.
