My son just bought an S-10 and it ran fine for a few days then he parked it went to start it and it wouldn't start. Checked the fuses. It was a ECM B fuse that blew. Replaced it, started the truck, it blew again. Replaced it again and it ran for about three miles. Then quit again.

You'l have to check that circuit for a short like a cam or crank sensors. Scan the engine as well as something may show up. Normally computers don't do that unless something has been messed with. Check the harness near the computer as you may have a line that has been pinched.
