PRE No-Start: I pulled the spark plugs (one at a time) just to check and make sure they were all in good condition. They all looked fine so I buttoned everything up and went to start it up. Well its cranking but it wont fire. I didnt pull anything other than one plug wire at a time and only from the spark plug itself. I went over all the connections and everything is as it should be. I switch the key on and the main relay switches on. This is all 10-15 minutes after I had been driving it for about an hour or so... Any thoughts?
