Asked by Mar 10, 2018 at 01:31 PM about the 2012 Ram 1500

Question type: Maintenance & Repair

Please Help, my son bought a Ram 1500 alt 4 x 4 w/the 4.7. Bought it used from a
dealer with 140,000 miles. One month after the purchase it wouldn't crank and
sent it back to the dealer since I had a warranty on it. They put a new fuel pump
and a new tipm box in. Has run fine for 18 months and had to put a new fuel pump
in. Ran fine for 2 months and having problems again. The truck starts right up and
idles fine for around 7 to 10 minutes then it dies and want start back up. Wait a
hour and does it again. When it dies, I can't get any power to the fuel pump. Tried
jumping direct power (from inside the tipm box ) from m7 fuse to the fuel relay
fuse(m27) w/no luck. I think it's a sencor that shuts everything down when it
warms up. Anyone have any suggestions? Thanks, Jake
