Customer Question

Vehicle = 2005 Ford Excursion Limited 6.8L V10
Issue = I just replaced the main under dash wiring harness, but now truck will not start. believed to be NO spark. Theft light blinking fast at key on, then blinking at a 5-6 time pattern. Truck cranks strong, can smell fuel if I pump the gas pedal so fuel is flowing.
What I Already tried......
1 - had an auto locksmith some by and try to reprogram my keys because I thought key program was lost, result was both keys are still have their programs. did fit the issue.
2- Had my PATS module around the ignition cylinder checked = no issue there
3- Reset the Fuel cut off switch under dash on the passenger floor panel.
4- tried different key-in key-out programming procedures found on fourms.
5- Tried disconnecting the negative battery cable for over 24 hours.

Welcome I'm Chris aka Moose

When you turn the key to RUN, the PATS theft light should come on solid for 5 seconds then go out, NOT flash. If its flashing then the computer thinks your thief and it will not allow the engine to start. For no spark you need to turn the key on and verify there is power to the coils, then use a scan tool to see if the computer is getting a crank sensor signal. If your getting this signal but the PCM is not ground pulsing the coils to make them produce spark then your PCM is faulty.
