My vehicle shut off going down the road. Got pulled home an replaced crankshaft position sensor thinking that would be the problem. Of course that wasn't the problem!! Now start troubleshooting an find there is no spark from coil to the distributor. My question is, is that confirmation that is definitely the coil that is bad or is there further troubleshooting left to diagnose the no spark?

If you don't have power coming out of the coil, that would be the place to start. However, you need to make sure you have power going into the coil to confirm it is the coil. The easiest way to do that is jump a known good voltage to it from the ASD relay or other source like the battery. Or just check for 12 volts on the Green/orange wire at the coil.

I attached the wiring diagram and other info for your review.

Let us know what you find and we can go from there. Thanks
