Ok I have 03 2500 with 24v HO engine Two years ago I installed a AirDog system.Three month's ago I had a start problem my truck's security system tripped. i started using the spate key with no additional problems until yesterday when had same problem. So took the truck to local dealer. I was told that I needed the retro-fit in tank pump installed. Because my pump was failing and that it wasn't a security problem. That light I was seeing was a throttle warning light. Yet when I called a second dealer I was told it sounds like a security issue. So question after long story will a faulty fuel system cause the security system to initiate?
