That would be my first ask as well, are you using OEM. Second, did you make any changes to engine or exhaust system. Do you have your vehicle tuned? Did you adjust any settings with AlphaOBD?

Other things to consider; constantly running fuel very low can overheat pump. Also, you may have contamination in your fuel system. Empty the tank and do a full visual inspection and get gas at a different station than you may usually use. Electrical issues ad mentioned above can also be a problem.

Good luck.

There is a fuel module computer chip in the system. Very possible this could be the problem. If going bad the fuel pump pressures are be kept at a lower fuel line pressure causing the pumps to work harder thus fuel pump burned up

I have a 2014 pick up thats a 2500 with 6.4 hemi, i just had my fuel pump replaced and have a few problems going on. First thing that happened was the first fuel pump ended up being sent back on warranty. I have the 2nd one in and have no overdrive and it slips pretty bad going into 4th gear. They ordered the fuel pumps from Napa by my Vin #. Now the shop wants to do transmission work. Its got 133k miles. Any ideas?

Welcome to the forum.

1) Does the new pump work correctly?
2) If pump is working correctly, you now have separate issue with transmission, correct?
3) For peace of mind, I'd get a second opinion on the transmission issue from another shop. Let's make sure while pulling that tank down there was no intrusion into any wiring harness...I'm sure it's fine and your second issue is just a coinkydink.
