I was wondering a couple things about the p1233 code. I know that it refers to fuel pump driver module (FPDM) and that the usual solution for this is a road-worn FPDM unit. However, I have replaced mine within the last 10 months and only received this code after erasing my original codes and the memory as well.
I was having issues with my fuel trim being to rich and hadn't purchased replacement O2 sensors until after my truck stalled on me and would not start. After I purchased new sensors, I reset the codes and the memory in order to see if I could get the engine to start so I could check the live fuel trim data before I opened the new O2 sensors and couldn't return them.
My real question is whether or not a "rich fuel trim" condition can lead to a p1233 code if left alone too long?
