I have a 94 S-10 blazer that I cant get any spark out of. I have replaced cap,rotor,coil,ignition control module,plugs,and wires within the last year. I also pulled the cap of and checked to make sure the rotor was turning and it was.(I also checked all the fuses) Its getting plenty of fuel just no spark at all.If anyone has any ideas your help would be greatly appreciated I'm at a stand still.Thanks

 

assume nothing.

new parts mean nothing.
Do you ahve spark to the distributor cap? A spark tester is a couple bucks. or pull the wire off and crank the engine over at night.

Got spark coming from teh coil?

Basically you need to start at the plugs and work your way back until you find the last plast you have spark. If you got nothing from the coil, take it in and get it tested.

 

You are right new parts do mean nothing! I pulled of the coil wire from the distributor and put a spark plug in it and still no spark. Had an old coil tried that and itfired instantly. (my coil was only 3 months old) Thanks for the help.

 

your welcome.

alot of people dont realize that these are high performance engines. They eat lower quality ignitionparts in a couple months. I am seriously considering upgrading to a mallory or other high performance ignition system.
