03 Dodge Ram Quad Cab 1500 w/5.7 2wd auto 70kmiles.
Parked truck for 6 hours came back out and would not start. Not even crank. Turn key to start position and no noise etc. Cleaned batt Terminals, batt checked out ok aswell, Starter was tested and passed, replaced ignition switch(still no start). Swapped Relay, Also swapped #14 and #20 Fuses(still no start). Pulled relay. Getting Voltage at the #30 Terminal, and ground from the #86 Terminal(pcm). Jumpered the #30 Terminal to #87 terminal(starter) and truck started right up with key in run position. Truck also turned off with the turn of the key, but still not getting anything when turning key to run position. Only thing I am thinking is a break in voltage between key and relay, as the #85 terminal on relay does not throw voltage when the key is on the start position(should it be?) Any ideas on what else it could be at this point? Also truck would not start in neutral with the turn of the key either(so don't think it is safety switch), And since when I jumpered the terminals together to start the truck from the relay it was sitting in park and did not seem as if it was in gear. And no trans problems previously reported. Kinda frustrated at this point. And to top things off we had nice 60degree weather 3 days ago and now lol it is 14 degrees so I'm freezing my butt of standing out there scratching my head(haha).
