A friend talked me into changing my leaking valve stem seals on my 90 jimmy S15, 4.3. We busted the heater intake coupler and then had to remove the manifold to have it tapped. Re-installed the Distributor aligning #1 Position with TDC on the 2nd mark. Re-adjusted the valve tension per Hayne’s at 120º degree turn for each cylinder's TDC. Wires are correct 1-6-5-4-3-2 on cap, from front 1-3-5 right side 2-4-6 left side.
Now it won’t fire. Nothin. No snap, crackle or pop. Just a whirring starter. The timing light says it’s at zero. We get spark to the plugs. The injectors are shooting gas into the TBI. We have not yet checked compression.
Coil tested fine but I bought a new one anyway and it still just sounds like it doesn’t want to turn over. Sounds like a whining starter with no compression. Does improper valve adjustment affect compression that much. Enough to keep it from firing? I'm ready to turn in my tools! :rotf:
