:runaround: I have an 86 s10 blazer. while driving, it suddenly stopped running. I am getting spark and fuel. it will crank. but will not start. can anyone please help me?

Is the Check engine light on? Have you checked it for trouble codes?
Inside the distributor, there's a "starwheel" on the distributor shaft, see if it has a crack.

To start you need 3 things
1. compression
2. Fuel, the right amount. Check plugs for fuel.
3. Spark at the right time.
