Hi. I'm new to this site and was hoping for some useful advice.

I drive a 1991 S10, 2.5l with a manual transmission. Note: it is not a Blazer. Up until a couple weeks ago, the truck was running fine. About three months ago, I replaced a bad alternator, and the plugs, wires, and belt at the same time. It ran with no problems for months.

Suddenly, it refused to start. It cranks and cranks, but refuses to turn over. It has gas and is getting a spark. I replaced the starter since it had the original. Same problem. I don't want to start replacing parts left and right. Any suggestions what might be causing this?

Thanks in advance.

 

It has been suggested to me that a fuse may be responsible. Does this sound like a possibility?

 

if it was my 93 350 I would check my ignition module in the distributor. Don't know if that applies to yours. Just a shot.

 

Crack in distributor , cap moisture in cap or both ? Cracks can be hard to see.
