Have an 05 lly cab chassis zf6 truck. Blew the edu fuse. Had wires rubbed thru on driverside connector at valve cover, harness smelled of burnt wires. Replace harness with new GM engine harness. Truck is not blowing edu fuse after harness install and will start and run. Throwing u0105 and u0073, have power and ground at ficm connector. Truck doesnt seem to be firing on #3,5,8 cylinders, Makes no difference when killing injectors with scanner on 3,5,8. Builds and carries desired rail pressue, balance on 3,5,8 is higher that the rest.
Anyone have any input. Feel this is 100% electrical. Like to try a ficm, but sounds like there failure is rare. (Any way to test the ficm). This truck was running fine all day, shut off for lunch, this happend when attempting to start afterward. 250k mile truck bone stock with 30k mile on a jasper long block and 8-10k mile on complete new fuel system from sending unit,filterhead,cp3, and injectors.
