I hope this is in the right spot. forgive me if not. I have a 1995 S10 Blazer with a 4.3 V6 Cpi. It was running good when I park in the drive way then the next morning it would not start. It is not firing at the plugs or the coil. I have tested the ignition module and it is good. I have changed the distributor cap and rotor button. Tested coil and tested bad on one test so I replaced the coil but it is still not firing at all. Any help would be great.
