Recently this week my fuel pump ECM failed (98K miles). Anyone else ever had this issue with their fuel ecm going out?

Luckily the part was covered under powertrain warranty, but dealer cant explain the failure. My thoughts are mud/water intrusion which caused a connector to corrode and fail

Thoughts?

I am having a fuel issue with my 2019 and have no warranty, replaced low pressure fuel pump assuming that was the issue because of the recall. After still having the same problem after replacing the pump. I came to the conclusion that it must be the ecu which is weird because the dealership told me they never have issues with them. I also have high km. I’m thinking that the pump failing may have also caused the ecu to fail. This was the second time the pump needed to be replaced and I think these garbage fuel pumps will be causing more than one issue for Tacoma owners

What kind of fuel issue are you having? Like running less MPG's? How many miles do you have on your truck and are they rough miles or?

I have no power going to the pump. The truck has roughly 112,000 miles or 180,000 km. They’ve mostly been highway miles, but I live in a small town so it’s been down a few rough/muddy roads too
