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? -
