No engine light. No theft/security light flashing.
I also have the same problem on my 2004 f150 xlt.
No engine light.
No theft/security light flashing.
It has the 5.4l triton. I checked for fuel all the way up to the fuel rail. Good pressure.
Coils have spark.
Ignition switch is good.
Crankshaft pos. Sensor has been replaced.
Has new spark plugs.
No burnt fuses.
I'm out of solutions. The only thing I can think of is a bad E.C.U...
ANY HELP WOULD BE GREATLY APPRECIATED
