Ghost-Trap

Tried replacing engine position, and timing sensors. Still no start.

Driver brought it in because he said it was running rough. Went to go get the truck but it wouldn't start, towed it to the shop. Don't think it's a fuel issue. It will run on either. Getting fuel at injectors. No active faults, tried swapping out vcu and ecu with working ones, still no start. Has anyone else experienced a similar issue with this? Thanks in advance.
