Check the plug wire from the ignition coil to the distributor cap.
If you haven't already, replace the distributor cap and rotor.
The GM Vortec's have issues with moisture getting inside the cap and rotor and causing problems.

I have a 95 chevy blazer with the 4.3 .i have tested and have spark entering the distributor but no spark leaving the distributor to plugs .have put new crank sensor ,cam pos sensor...


That is indeed odd. I would suspect problems with the hi tension cables if this was not part of the ones you changed since the flow of current ends at the distributor. Check also other cables such as the ground. It is puzzling that all plugs would not have any spark. I would also recommend a scanner used to check for error codes given out by the car's ECU.

Rought idle


There is a tester you can use that screws on the radiator cap and you can pump it up to see if it has a leak down effect in the system.. This wont tell you where its exactly going but tells you if there is a leak in the head or intake gasket.. probably should start with the intake and replace it and see if it does the trick .. if not then tear it down and replace the head gaskets and or check heads for cracks also.. thanks Jerry
