As far as I know, our generation of trucks were never offered with an active alarm system. Only a PATS system that kills the engine. Sounds like its time to go on hacker patrol, fixing any damaged wiring and removing any non-stock electronics.

 

Okay so my code i got was P0102, Which is the for MAF. Well i open up the air fox to find no air filter and that MAF was unplugged. So i plugged it in and it ran better but still not right. Put in a new filter and again it runs better but not right. I tried brake cleaner on the MAF but doesnt make any difference. Should i check the voltage to see if the MAF is even good? I cleared my codes before i did all of this and so far i have no codes pending. Just got to wait it out i guess.

Got my taillights all working, Now the only things left to fix whould be my heater(doesnt even turn on). My button for 4x4 doesnt do anything when i turn it(possible solenoid?) No lights come on my dash(for the 4x4) when i turn the button. When i turn my lights on and I open my door, my gauge lights come on. If i shut my door they go off. any idea? Door switch maybe?(didnt think that whould effect my guage lights though)

Found a killswitch button under my dash on the driver side. Guessing its for an aftermarket alarm system. Ganna see if i can throw out the whole thing.

 

Was your truck in a flood? Sounds like water corroded your whole electrical system. I hate to say it but you'll be chasing ghost problems.

 

This threads old, i had 2 bad grounds on the passeger side under the glove box. They solved my problems, now i just need to put a lower intake gasket in it.
