My brothers 98. 5 CTD 5 speed truck broke down on Saturday while driving to my home. He is getting a code P0230... Transfer pump [lift pump] curcuit out of range. The truck has a Holley blue pump using the LP harness as a triggered relay. I tried disconnecting the harness altogether & no changes. I need a ECM for this truck soon & hoping to find one local if possible for a quick install.
