We really need some help here. Have a 1991 S10 Blazer, just bought it less than a month ago. Driving down the road, it died, would not restart.

OK, so we got it to my parents' house, replaced the Spark Plugs, Wires, and Coil, it started.

Then, we get it to my house, and turn it off, it won't start again. Had the ICM checked, it's good. Replaced the Distributor Cap, STILL no starting.

It is NOT getting spark, we know that for sure, so what else could be the problem?

At wits end here, about to junk it, but really don't want to, I've got over $2000 in it right now.

Thanks in advance for any help!

 

possible crank sensor maybe? those are common and kinda easy to replace, its at the very bottom front of the engine. last time i seen one go out the truck had neither spark nor fuel.

 

Second the motion. Check out the DIY.

 

I don't know about everyone else's '91 but mine DOES NOT have a crank sensor...

Check your pick up coil. Mine had no spark not long ago...Didn't know why until I found this...

 

This what?

Ummm so the OP has HEI? My bad. Yeah.. the pickup. Say, tommyboy, does your truck have a tach? No bounce on crank, definimundo!

{good to be wrong once in a while, keeps me humble!}
Nobody facepalms good as Picard!

 

It's all good...

"This" would be the broken chunk on the pickup coil.

 

i second the pick up coil had the same issue on mine would only act up everyonce in awhile and not start and i replaced the icm while i was in there
