2012 Tundra 5.7 4x4 flex fuel PROBLEMS

I have a 2012 tundra 5.7 4x4 and about 6 months ago the truck hesitated to start all the time until the fuel pump stopped working. I took it to the mechanic and he changed the fuel pump and it’s been 6 months and the truck is starting to hesitate again. I think something is messing up the fuel Pump. I don’t really use the truck during weekdays because I have a company Truck and my tundra is never low on gas. I spent 1200 to fix the fuel pump and now it’s starting to do the same damn thing.

 

I bought it from the dealer. $750

 

Try to see if there is anything the dealer can recognize from the previous job.

 

I bought it from the dealer and a different mechanic installed it.

 

Check and or reset the alcohol density / fuel trim settings before you replace anything again. There are a bunch of threads on this issue. It might just need a reset and not a fuel pump. Dealer charged me $100 to reset once but I bought the software from Ebay the second time for $30 to do it myself.
