I bought this truck (1500) used. I soon realized only the dash tweeters worked and after lots of troubleshooting, I decided it was likely the factory infinity amp causing the issue (there is a aftermarket receiver unit installed using a C2R-CHYD wiring interface). I decided to remove the factory AMP (since I did not want a faulty item being powered) by pulling out the dash in-order-to remove it. I then proceeded in running my own speaker wires, AMP and new receiver unit.
Now my truck will not start and the alarm begins going off randomly, My fob hardly ever works. My battery is reading 12.6 volts (I believe, I need to double check). I have tried to disconnect the battery and wait. I have also tried to disconnect, and connect the positive and negative wires together for a few hours, still nothing. I have reset the computer by holding down the trip button while turning on the ignition. I am currently out of Ideas. I have double checked, and my new radio only has a connection to V+, GND, ACC, Reverse Notification and Parking Brake notification. There is no CAN connection. It looks like the infinity AMP may be connected to the CAN, is having it unplugged causing my issues?
All installation work I performed was done with the negative side of the battery disconnected, so I would not have expected some weird discharge which would affect the computer.
Could something have happened with one of the wiring harnesses to the doors which would mess up the security system? This is the only other thing I could think of.
I was able to get the truck started by sitting with the key in the "on" position and keeping my foot on the brake, every once in a while the engine would try to turn over, after about ten minutes the truck started, I drove a while and the security alarm light and the low tire pressure light would come on together and then go off. After about ten minutes of driving, I parked, turned off the truck and tried to turn it on again with no success.
