Im sure this is out there already, but still new and trying to figure out this place. 2002 5.9 L. Previous owner had installed 20miles of wire and extras under the dash, when he/she sold the truck they took all the "hard" accessories with them and left the wires attached to every power source they could. Ive had the truck for a year, but was in the shop for 4 1/2 months, so really havent had it that long. (mechanical issues...plus insurance, parts delays, covid!) Anyway, have spent the last 3 days trying to clean all that up plus replace external voltage reg they installed. plus new alternator, and still not charging. had the old one tested, and it was bad. Now wires cleaned up, new mounting point for V Reg and cleaner connections in engine bay. Sooo, Now, This morning I go out to fire it up. Starts right away, but NO gauges, not charging and pulled all these codes. 230, 382, 463, 753, 1388, 1389, 1492, 1687, 1693, 1765, This doesnt really seem right. The only one that really concerns me is the fuel issue, My last truck, 01 2500, went through 3 lift pumps then, Yup VP rebuild. so that makes me a little nervous. Any suggestions would be helpful, (no not a P pump conv&#128540 or just point me in the right direction of the proper threads. Thanks
