Hi all,
I’m in kinda a pickle so I’m looking for advice. I’m just coming back from a deployment and will need my truck once I get released and head home to pick it up.
It’s a 2012 1500 4x4 5.7 4 door.
Before I deployed it ran and drove fine, only a few little issues like having to replace the master window switch control in the drivers door. Nothing big. Anyhoo…. The wife has been driving it once a week to take the dogs places and keep the truck from sitting. Then one day she went out, hit the fob and it had a crank, no start. Tried it a few times then tried the other fob. Still nothing. She called our neighbor and he came over, looked things over and put the key in and it started right up. She was mad because she felt stupid. Next week she had the same thing happen so she tries the key in the ignition, no luck. Crank and no start. Tried the other key, fired up. So off she goes with the dogs but after dropping them off, the truck does it again. This time no crank or start. Call the neighbor and he comes to look. Says your battery is dead and the neutral cable looks ready for replacement. They jump it and get it home with more thanks to him for helping.
He comes by a couple days later with a new battery and cable, swaps them out, problem solved, right? Nope. Wife gets a couple weeks of no issues then gets stranded again. The crank, no start is back. At this point she’s far from happy and called me in the middle of my night overseas to cuss me out. lol. Convinced her to get the neighbor to get it to run and take it to a shop he actually trusts. Shop keeps it a week and could never get it to replicate the issue, started every time, cold, hot, after driving, etc. ok… So paid him for the effort and took it home.
Next week she goes to start it and nothing. No crank or start. Have her FaceTime me so I can see and there is nothing. No lights, gauge movement, nothing. Battery (the new one) is dead again. FML.
So what I’m looking for is advice from those who’ve played this Tipm game.
I’m thinking one of two possibilities.
The crank/no start could be the Tipm not turning on the fuel pump. It always fielded up in about a second when it isn’t having a problem. The other thought is it isn’t turning off the fuel pump when she parks it (she wouldn’t know to recognize it) which is killing the battery. Does that sound logical? And does that fuel pump bypass from MAKs sound like an actual fix?
Not being there to dig into diagnostics makes this hard so I’m trying to benchelrace my way through it before I get home.
The only other thing I can think of is the Tipm isn’t telling the alternator to charge the battery but I would think if that happened while she was driving it she would have seen a CEL and the voltage gauge would read zero. No?
I don’t know enough about the Tipm and I really will only have a very small window of time to deal with getting the truck running.
Any help and advice would be Very Much APPRECIATED!! Fire away! Thanks!
