2010 F150 Cranks wont start no fuel
We had a problem a month ago where it would crank and not start. After some trouble shooting we found a bad connection on the fuel pump fuse and installed a new fuse and things worked fine. A couple days ago it happened again, we checked the fuse it was good replaced the relay still cranks no start.
Replaced both the fuel pump driver module and fuel pump still wont start. We hear the pump run for a couple seconds then shuts off.
I have not checked fuel pressure on the fuel rail yet hoping to see if there might be something else to look at as well. I have sprayed starter fluid into air intake and engine will fire so pretty sure its not getting fuel.
Sound like it is a new fuel pump, and it does prime up...and the motor will run with starting fluid for a bit. Yes I would check fuel pump pressure and do a bleed down test to see if it holds pressure, I don't know what the pressure should be on a Ford, but the pressure should not drop more that 5lbs and hold for at least 3 to 5 min. If not there would be a leak to investigate.
Thanks yes new fuel pump........ my plan after work tomorrow is to get a pressure gauge and check pressure I've been reading about an inertia switch but apparently Ford may have done away with them after 2009 I've looked all over and cant find one on mine even behind the kick panel.
I have a similar problem on my 2009 F-150. Changed the whole sending unit with the fuel pump with a OEM motorcraft, changed the fuel pump module. It will stall out after a long drive or after I shut it off it won't restart until it cools off for at least a half hour. Please let me know if you figureed yours out.
rsilmi925, in your case, it sounds to me like you have an ignition problem. I am not familiar with Ford that well, but in most cases what you describe is contributed to the ignition control module. When they start to go bad, heat affects them to the point that you need to cool the motor down in order for it to function again. The ignition system components on yours is where I would start looking.
