I removed the black foam surrounding the injection lines to get better access to the rail pressure sensor.

I had unplugged the connection for the first bank of injectors and forgot to plug it back in when I was done.

I started the truck and turned it off 5 seconds after I heard the idle.

I plugged the injector wiring back in and started it again, it usually ran after that, but after i turned it off, it won't turn back on.

I'm now getting codes P0201, P0202, and P0203 (the bank of injectors I unplugged).

There's no crank, but it sounds like it's beginning a crank and stops. just a single "chunk."

At this point, I'm hoping it's as simple as the VC gasket/injector harness or a new ECM/PCM, but I'm resigned to shelling out the money for injectors if that's what it takes.

I did find troubleshooting for the injectors but I can't find a pinout for my 2017
