I just replaced the main under dash wiring harness, but now truck will not start. I believe it 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.
6- There are no OBD codes present

You can not program anything with a scanner, second, if you unhook or take the power away from a pats system for how ever long it will retain it's memory, it is just like a computer. Because you replaced the harness it was a disconnect to the theft system and it probably needs reset, not just the keys. Here is a guide to help
