Having problems with your 1989 Chevrolet S-10 Blazer ?
89 s10 Blazer No spark
\015 I have a similar problem with my buddy's truck. We have replaced all that was previously mentioned; plugs, wires, rotor, cap and coil: as well as the Igniton Module, Map Sensor, Pickup Coil, and ECM. We have checked every fuse we could possibly find. We do have fuel at the throttle body. The only conclusion I can come to is there must be a broken wire somewhere in the wiring harness, unless there is another component we are missing. Have not replaced the Knock Sensor or oxygen sensor yet. Any ideas???\015
