CRANK SHAFT SENSOR STOP FUEL ?

1996 GMC Jimmy • 250,000 miles

Gmc 4.3l how does the crank shaft sensor stop fuel flow to the injectors when all injectors are stopping correctly? Needing to know how the sensor affects the fuel flow and how can it stop fuel flow completely

The CPS has nothing to do with stopping fuel from entering the engine, check to see if you have a shorted injector causing the problem, go here for more info.
