I just bought a 2005 Ram 1500 with the Hemi and it had no problems with it. I drove it three hundred miles home with no problems. It now will not start unless you hold the gas pedal to the floor. Once it starts it runs fine with no problems. I didn't know if the had a TPS sensor since they were drive by wire and this could be causing it. I have seen on the internet that other people have been having the same problem I can't find what it took to fix it. Please help!
