Question about 1988 GMC Jimmy
The way to test this coil is to remove a spark plug wire and put a screw driver into the boot put the screw driver 1/4 inch away from bake metal crank over the engine if it has a blue spark it is ok. The most common problem on these coils is not the coil itself but the rotor button in the distributor cap so repace the distributor cap first if you have a problem with it running. you also need to use dielectric greese on the boots of the plug wires so they will not arc out against each other. yo test the coil you need a ohm meter and need to test the primary ans secondary windings with ohm meter, do you own one if so let me know If you need more help post a reply here.
