No crank no start no click – GM

No crank no start no click – GM

GM has issued a technical service bulletin (TSB) #PIP4208 to deal with a no crank, no start, no click situation on the following vehicles:

2006-2008 Chevrolet Cobalt
2006-2008 Chevrolet HHR
2006-2008 Chevrolet Malibu
2007-2008 Pontiac G5
2007-2008 Pontiac G6
2006 Pontiac Pursuit (Canada Only)
2006-2008 Pontiac Solstice
2006-2007 Saturn ION
2006-2008 Saturn Sky

The starting procedure on these vehicles is fairly complicated and the root problem lies in the ignition switch. The ignition switch does NOT directly control the starter motor like in older designs. In this vintage, GM uses the ignition switch as a signaling device to tell the body control module the position of the lock cylinder. There’s one voltage when the key is in the lock position, another when it’s in the START, and a third when it’s in the RUN position. But the BCM should never see voltage when the key is in the ACC position. In some cases, the ignition switch may malfunction resulting in an engine no crank concern with no trouble codes.

If voltage is present on this circuit when in the crank position, inspect the circuit for a short to voltage with both ends of the circuit disconnected. If the circuit is not
shorted to voltage, replace the ignition switch for evaluation.
