2012 GMC C2500 Repair Question
91 GMC 2500 not cranking
Disconnect the coil wire at the distributor, ground it and crank engine over-do you have spark. If so replace the Cap and Rotor it has to make it out of there to the plugs. If not do below.
Test for power at the coil positive terminal and also the resistances of the pick-up coil in the distributor.
