Well I was having a problem with the ECMB fuse blowing, and when it would blow the ECM would lose all codes, but I have fixed a few grounds and the ECMB fuse doesnt blow anymore, still no prime or run from pump, turn key on, engine light flashes once then stays on and I can hear the fuel pump relay click.. then a few seconds later click again. But the night before the truck stopped running I had gotten the code 42. Then just shut off in reverse and pump will no run. Everything else seems to work. maybe the fuse block inside had bad connections?
