1st i cleaned all the oil out of the spark plug tubes and I changed my valve cover gaskets and the (ring) gaskets at the bottom of the spark plug tubes. i put the rocker arms back into position, and i tightened it down ( maybe a lilttle to tight ) new plugs, new wires made sure the arm werent stuck down, and buttoned the vavle cover back down , put all the plug wires back in thriple checked firing order and it will crack over but wont start. Every thing ran great before i changed the gaskets PLEASE HELP !!!! I KNOW ITS SOMETHING SIMPLE!!!!!

 

Check your grounds and electrical connectors

 

You may have blown a fuse or your coil. Check for spark.

 

It could be bad wires or plugs.
