Chevy Silverado No Start

Why won’t my Chevy Silverado Start

Shops are reporting Chevy Silverado No Start pattern failures on the ignition systems on 1999-2007 Chevrolet Silverado 1500 4.3L vehicles. The problem is usually caused by a broken ground wire at the ignition coil. This wire is white/black and may not appear to be broken. But the wire inside frays and causes intermittent no-start conditions. To check the condition of the wire is the vehicle does start, run the engine at operating temperature and have someone wiggle the wire and listen for misfire. This wire can cause misfire codes, no start, intermittent no start, intermittent misfiring, and buck/jerk while driving. Once you find the troublesome section, splice in a new wire and seal the connections with heat shrinkable tubing or 3M 06147 tape.
