I have a 2010 Ford F150 XLT and have had a couple of instances where after driving parking and go into a store and back out and try to start the truck I would put the key in the ignition and turn it the lights and chimes would all work but it won't start (no starter noise, clicks etc.) after trying several times after a period of time it will turn over. Now it happened again and this time a wrench light came on (not the check engine light) took it to the dealership and the light was off and they could't recreate the issue and they said there were no codes. Now when I drive the wrench light will come on and if I turn off the truck and immediately try to start it backup it will not turn over just the lights and chimes. After sitting for a while it will start up with no wrench light at startup. Any ideas?

 

The wrench light is generic - it means a sensor has gone out of tolerance. If the problem persists, then it will trip the CEL and store a code.
