2001 Ford F-150 Alarm system Malfunction

  • 2001 FORD F-150

Electrical problem
2001 Ford F150 V8 Four Wheel Drive Automatic 78000 miles

Blinking Alarm signal, truck wont start, Steady signal, truck starts. Problem started 3-4 months ago. Used to work sometimes when I pulled key out, flipped it around and retried. I had a diagnostic done with a false positive of a faulty 02 sensor. Didn't work! Replaced Battery today from a 650 amp to 850 amp. Doesn't work. The only luck I have had in the past 3 days is when the truck has sat all night and the battery is dead, I can jump start it in the morning 1x but after it runs and I switch it off, it will not restart.
Called a Mechanic, told me to go to dealership, dealership charges 89.00 just to look and would then give me an estimate. I have read online posts an it seems to be an epidemic. I read that there is a switch I can depress under steering column but through the mass of electrical wires I can't find any such button. I don't know if it was aftermarket, I would say no, but who knows. All I know is that it is driving me insane and I wish I could just yank the alarm system out all together without have to spend the money at the dealership.

Do you
have the same problem?

Done messing with it, told dealership to casterate alarm system.
Funny, I own a Ford explorer with a bogus alarm system that keeps draining the Battery.
Fords are nice but alarms and automatic doors/windows/locks/ suck.

Was this
