    No Start P0201, 202, & 203 - Probably My Fault

    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

    Hopefully it’s not a big deal and you can get back on the road quickly.

    I’m sorry I’m not savvy in this area, but I’m sure @AK_Bob is probably finding the troubleshooting guides right now.

    Good luck brother.

    Attached is the troubleshooting guide for P0201, I haven’t had a chance to study it yet.

    The other two codes are the same for injectors 2 & 3.

    I would start by performing the checks listed.

    I will find and attach the other two codes.

    Attached are the other two codes; it looks like they are all the same, so the information is duplicated.

    If all resistance checks are okay and no shorts to the ground, I would check all fuses for an open.

    Then clear the codes and see if she will run.

    Please keep us posted.

    I got it started!

    Do you ever forget to look at the simplest things first?

    After many days of checking voltage and resistance across everything, i finally checked my battery voltage 10v.

    Just a dead battery was causing codes.

    I appreciate the help still.

    Glad it was an easy fix.

    My biggest fear was that perhaps you had accidentally fried the injector driver.

    A classic case of we couldn’t see the forest because of the trees, LOL.
