Wondering if the alarm system and door locks are tied into the ignition.

(1999 Ford F-250 Super Duty)
I think it has something to do with the alarm system & door locks. I have no power going to the solenoid for the starter but I can turn ignition switch to aux, touch terminals with a screwdriver & it starts & runs great. When I turn it off I have to repeat the process. Doors won't lock with buttons either but hear the clicking sound.

Do you have a PATS system. Door locks are not wired to ignition.

I don't know which system it is as I bought it used and already installed. I would be more than willing to disable, uninstall, trash or whatever it takes to the alarm if that fixes this problem. Do I need to take it to a repair shop or is this something I can do myself?

If there is a theft light it is more then likely a PATS system. It would have to be scanned to find the fault. If not the neutral safety or clutch switch needs checked for circuit to close to the relay. Door locks will be a seperate circuit test.

Yes, there is an theft light. Can the system be be bypassed permanently or do I have to take it to a dealer to have it scanned & repaired/removed?

The dealer is not the only one who can do it. I and many other shops have the capability to do those as well. Check with someone in your area before going to the dealer.

Found the alarm book today and set it to valet mode, still didn't start. Tested and found the start solenoid was bad. Replaced it and it starts & runs fine now. Thank you for your quick responses and assistance. Greatly appreciated.
