1991 S10 Blazer 4x4, 4.3L V6 Won't start

Asked by 9Blaze1 Sep 14, 2021 at 10:30 PM about the 1991 Chevrolet S-10 Tahoe 4WD

Question type: Maintenance & Repair

I have a 1991 Chevy S10 Blazer 4x4 that suddenly will not start.  If  I hook it up
to my truck and pull it around the block, once I get beck it will start right up.  
Found this out the first time it happened when I pulled it to a nearby mechanic
for the no start issue, once I arrived there, the truck started right up.  The same
thing has happened 2 other times since then.  Any ideas what it might be?

You have to test for proper spark , fuel pressure and injector pulse when the problem occurs

Is it not cranking? Is it cranking but not starting? Or do you hear the starter spinning but not turning the engine? Jim
