Got a 05 f150 w/ the 5.4 and a code systems remote start, keyless, and anti-theft. I pushed the remote start button the other morning, it cranked but didn't start... no big deal, I thought it would cycle thru and try again like my old colorado did... nope. So i go out and try pushing the unlock button on the remote... nothing. I went and changed the battery in the remote and still nothing. So i called the ford dealership and they said to use my door pad to get in and press the brake pedal to negate any effect that the remote starter had on the truck. So i punch in my number and the factory alarm starts going off. Press the brake, put the key in the ignition, turn it, try to start it, put the key in the drivers door to lock and unlock it... nothing. So the only way to stop the alarm was to disconnect the battery. Let it sit for a while, reconnected the battery and the alarm starts going off again. Left it disconnected all day, came home, reconnected it and same think, alarm goes off. I called the dealership again and they said its something with the remote starter system and they don't deal with that issue on the 05's. So they told me to call a different place that does most of their work w/ remote starters and the guy there said that they don't deal w/code alarms any more... basically, good luck.

So I ended up finding a guy at custom radio that is willing to take a look at it. Its gonna cost $110 just to get it there by flatbed, then who knows how much to fix it? I've been messing around with it... I found the valet button on the alarm system, so now i can at least have the battery hooked up without the alarm going off. I try to start it and it just click's. I found the brain box for the remote start system, unhooked everything and tried to start it, and it does nothing... doesn't even click. I'm clueless??? Any ideas??? Thanks

 

their should be wiring diagram on back of unit pull dash apart below steering column trace wire into ign switch where they t in find the red and light blue it is probably cut in half rejoin it this should alow it to start then you can drive to place to have them tell you it has to come out or you could remmove yourself trace wires that come outof module labeled ford remote start and start cutting it out and taping or unsolder if you are comfortable doing that. any more question just ask

 

Well... i tried joining the 2 wires back together and nothing happened, still wouldn't even turn over. So I sacked up and paid the 110 bucks to have it flat bedded to custom radio. I'm so f*cking frustrated with that truck... I was about to drop a match in the gas tank!!! Hopefully its something really stupid and easy and cheap to fix........ ya right, who am I kidding!?!?!
