I've read through the forums.. tried millions of ways nothing is working.. any other ideas? I just cut the wire to the passlock in desperation, and still not starting.


I unplugged my PCM to check the prongs because I am throwin a 303 cylinder misfire. New coil, new spark plug.., it's still throwing the code.. Now I'm stuck in pass lock and truck will crank but NOT start. What is the actual procedure to disengage the stupid fuckin pass lock? I'm supposed to be on the road to CO this morning and I've been fuckin with this all day.. I need to get this truck running asap. thanks for any help offered.

Hit up Supermod or Limequat, believe they are the only 2 that could help you. I think it has to get tuned out or new PCM.

Seems like I remember something like if you leave the ignition on for ten minutes, then try it, it should bypass the pass lock and start.

Hook the wires back together, then turn the key to on and leave it 8-10 minutes until the passlock light goes out, then turn key to off and then start the truck.. once the truck is stated disconnect those wires and it wont happen again.. however the passlock light will stay on.. then get the passlock disabled with a tune. I had jeremy at limequat do mine.. that alone was worth the 99 dollars

Is the vehicle still cranking after that first failed attempt? It's been my experience that the truck won't crank if it's Passlock (had a loose ground on my remote start...).
