Chevrolet Express 4500

Vehicle broke down with a crank no start condition. Verified no fuel pressure. Diagnostics revealed no continuity between tank fuel pump positive lead at fuel pump relay, and ground. Removed fuel tank, disconnected fuel pump wiring harness, and found burned pin at positive terminal of fuel pump and mating harness connector. Harness displayed significant distortion and charring consistent with a poor connection.

ABS Valve Body / Pump Harness chafed through brake hydraulic line near transmission crossmember. This resulted in a hydraulic leak and loss of brake pedal feel / partial loss of brakes. Fortunately failure occurred in the driveway--I had 4500 Lbs of sailboat trailer hitched to the van and was about to go on a long trip. Design issue. Wiring harness should not be located so as to chafe on hydraulic lines. This is not the first chafe related failure on this vehicle.
