do you have the #2 and #7 pigtail harness update? if so youll notice a bracket holding the injector harness at #7. If not that is more than likely your issue. Unplug #7 connector and look at the end, if it has some tan looking dust at the terminals its shot. Some times you can unplug and replug it and start truck and itll be fine but, it will act up again. You are getting multiple codes because when one inj. circuit fails the ficm shuts off corresponding cylinders (a pair on each bank) and will set the p2146 code in your case.
