HELP!! Wont Start!!!

Ok so this morning one of my buddies wanted me to start it up so he could hear it, i have the HMF slip on and the HMF optimizer, but it start up and ran just fine and then this afternoon we got back from work and i unloaded it so he could give it a test drive well i got on it to start it and all it would do is crank and nothing else. its gettin both spark and fuel! so what could it be? Any thoughts would be greatly appreciated

I would check your connections on your optimizer, it just takes one cable togive you those problems.

How have you confirmed its getting spark and fuel?

I like your Christ. I do not like your Christians. Your Christians are so unlike your Christ.

Make sure your gas tank is not empty and the petcock is ON. Not saying you didn't check it, just basic trouble shooting. Be sure the Plug wire is properly connected to the spark plug. Another thing, I was riding and a tree branch snapped the tabs on a fuel shut off switch in the front of the quad. Its there in case you flip the atv upside down. I had to zip tie it upright. Its was swinging from the wire in front of the radiator when it happened to me.

Try a shot of carb spray in the intake while cranking, to see if it farts. I know you said you saw spark but a new plug is cheap, I have seen plugs that fire when tested, but won't under compression. What is your battery voltage? Low battery voltage will cause a crank but no start on any fuel injected engine. Lastly, I would try it with the fuel optimizer disconnected.
