I have a '91 S-10 Blazer with about 165,000 on it. It died on me after losing power and backfiring a couple of times. I found the electrode on the rotor broke off. Replaced the rotor and the engine still will not fire. While towing it off the road the ignition coil burnt out. Replaced the ignition coil and the pick up coil on the distributor. Checked the ignition module - passed. Still will not fire. The supply to the ignition coil shows 12 volts. When I crank the engine it drops to about 8 volts. I pulled the coil wire from the coil and jumped with a screwdriver to see if I got an arc from it and the post on the coil. No spark. Where do I go from here? What further checks do I need to do to isolate the problem?
have the same problem?
