Message: [QUOTE="300000 and counting, post: 1401751, member: 10868"] I'm going to be buying a 6.4 that was wrecked and rolled on its passenger side, it hasn't been started since the wreck, and when he tried starting it today (almost a year after sitting) the starter didn't do anything. But the truck had the following codes: P0231 Fuel Pump Secondary Circuit low P0232 Fuel Pump Secondary Circuit high P0381 Glow plug/ heater indicator circuit U3F03 Unknown DTC P1635 GM: 5 Volt Reference Circuit (tire and axle out of range) Do I need to be worried about anything? I'm thinking the low and high fuel pump circuit is due to the fuel switch In the dash popping off in the wreck, would that be correct? I don't know what the glow plug issue would be, I don't know what the U3F03 is and the P1635 is because the axle got screwed up in the wreck. Also when the truck rolled the batteries got ripped out but he doesn't know if the truck was shut off at that point or not, would have the truck shut off without batteries? If not would the truck run long enough to damage anything? [/QUOTE]
