Asked by Cory Aug 19, 2020 at 05:23 AM about the 1999 Chevrolet Blazer 2-Door RWD

Question type: Maintenance & Repair

99 Blazer rwd 4.3L v6
I recently replaced the head gaskets and now that I
have it all put back together, it won't start. I made
sure to mark the distributor. I put the push rods in a
cardboard box, Tighten the lifters to spec. (ect.). I
followed all the manuals steps. So I'm stumped. I
checked the fuel rail and it's getting fuel. So I
believe it's either no spark or no compression. Any
help would be extremely useful.

So I am getting spark. hooked it up to a spark plug tester. I rented a compression tester. So far I got no compression at all. 0. So what could 0 compression on all cylinders?

No compression on all 6 cylinders. Hello. I am coming back to this post cuz I'm still having trouble. Blazer is not getting compression on any cylinders. I've check the stroter valve and I am getting fuel. I checked the spark plugs and I am getting spark. I rented a compression tester and tested compression. All 6 come back with zero compression. What could the cause be ?

I was wondering if maybe it could be blown piston rings or a distributor could be slightly off ?
