Have you pulled the sparkplug wire off the #1 plug. and use a spare plug into the boot. Becareful at this point it will shock you. Turn the car over and see if there is a spark created from the spare plug. The Silverado's have a few fuseable links they are inline of certian wires. You might have a bad fuseable link. You also need to check Grounding points and ground wires. If they are rusted or broke it can prevent your system from making a complete circuit . Time to chase wire with a voltage tester. checking sections of wire at a time. with out being there to look over the system. That are a few suggestions.

Check to see if you have Power at the coil when the ignition is in the run position. Try to put the points on High cam so the points do not burn when you do this test. Also see if your Rotor is turning. You could have a broken timing chain or sheared off a Drive pin in the Distributor gear.

Check your Polarity at the coil. I do not see a new condenser as a replaced part, try a new one. Would be interested in knowing what you found.

Check to make sure the coil wire is secured to the distributor cap and rotor.
Also check that the rotor is not cracked (even if new) and that the spark plugs are not loose - wires are not loose, frayed etc.
Also, make sure all connections on the battery, ground at chassi, and positive on starter are in good repair as well.
Please, let me know if you need further assistance.

No start on old gasoline forklift engine.


most likely the ign switch is ok if you are getting spark. so you have a hot spark at coil and weak fire at plugs? if you have a test light check the positive side of coil for power when turning key on and cranking. if it is dropping power on positive side then ign switch could be bad. can "hotwire" coil by jumping a wire to positive side of coil to pos of battery this will eliminate ign switch.

Pull one or two sparkplugs and check them for moisture; not fuel, but for water beads.
I don't know how long your engine ran after losing coolant but there is a chance that you lost the head gasket and have gotten water into the cylinders.
