You did not say if you have changed the coil or not. the coil is what give's it the firing power it needs to crank as well as to run smooth. Replace the coil. let me know how it does.

I keep losing spark on my 86 toyota, hot or cold


Sounds like a bad coil. But a sensor like a module or an aging distributor cap and rotor are the most suspect. Take off the distributor cap and see if a white powdery substance is building up scrape it clean with a sharp knife... it may run for a few months best to replace the rotor and distributor cap

Cranks but wont start


Engines need three things to run. Air, Fuel, and Spark. If you can verify the air cleaner is clear, and fuel is available at the carb, then the ignition timing must be the issue. Check to see if the distributor, and cap that you installed, are still tight. Check for spark by removing one spark plug boot, insert one of your old spark plugs, and have someone crank the engine for you to see if you have spark. Air, Fuel, and Spark, its one of this three.

How to install cap and rotor on a 2000 chevy blazer 4.3ltre v-6


Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.
