Hello all

Just looking for some help or any ideas. I have a 2003 GMC Savana 3500 Cargo that had a Security (passlock) issue. I think I have that part fixed, the security light does not come on any more. The van just cranks, it does not "try" to start or start & stall. I have checked all fuses, pulled all the TSB's and saw that there were a couple of ground issues, checked and cleaned all of them. Ran the codes and I get nothing. The part I find odd is as soon as I turn the key to the "on" position, the trailer turn / stop relay's just click (the relays mounted on the frame rail under the drivers door). I have another 2003 GMC Savana and just for the sake of it I tried turning the key on in that one and no clicking from the relays.

Any help or Idea's would be appreciated.

2003 GMC Savana 3500 6.0L, towing package, 6L80E
