MJ turned over just fine but wouldn't start for nothin. rolled it out of the driveway and took the XJ to work. Got home and checked all the connections, and still no MJ start, battery voltage ok, so rolled it into driveway and Dad pulls a plug wire and hooks up his home brew spark testor. I crank it over and she starts up just fine on 3 cylinders 
shut it down and re-attach the wire and it starts again. Then my dad mentions he had checked the gas cap while I was inside for a minute and heard a big wooosh of air! I often get that when I stop for gas. (or when I have gas :moon: ) Would this be the reason it wasn't starting? I searched and found this thread , mentions a vapor line with a filter and a canister to check, anyone else run into this issue?
