IMG_2627.MOV I have a Sierra 1500 with the 6.2L (107k miles) and 10-speed transmission. When I was driving the motor shut off and when I tried to restart the engine the starter would just crank but no fire. I towed it to a mechanic I’ve been seeing for a while. He hasn’t been able to get around to diagnosing the truck but he sent me a video of him trying to start it. The noises are very concerning; I first thought it was due to a failed fuel pump module but now I’m thinking it’s something a lot more expensive anybody have any ideas as to what this problem could be?
Anyone have any experience with Gibson cat backs? I have a 2019 AT4 and looking for just a little more growl to the exhaust. Here is what i am looking to get: https://gibsonperformance.com/i-23266766-dual-split-exhaust-system-stainless-65688.html#!year%3D2019||make%3DGMC||model%3DSIERRA 1500%2C SLT
