I still need help. '97 S-10, L4. It went from no spark to weak spark with a new coil pack. From weak spark to good spark with new wires. But still not firing on 2-3. 1-4 are firing right and on time. No wires are crossed So at least I know I'm not replacing good parts. I'm thinking it may have a fuel delivery problem also. The plug doesn't have a heavy gas smell, just a whiff. Any suggestions as to what to look for and do next?

 

check the gaps.
