You said that you checked the plug but didn't say if your actually had spark. I would start there, Could be other things like compressions problems. If under 90 your done.

I can see spark at the plug but how bright or strong should it be? and I squirted some oil in the head. But still no start. Will check the head gasket now I guess. Thank you guys for your help
