Need some engine help

My #7 cylinder doesnt seem to be firing. I have compression and spark(kinda orangy though) but the header tube doesnt get hot, and it runs the same with the plug cap on or off. What do you guys think I should try?

Check for vacume leaks. Many times the vacume T fitting is in the intake runner leading to cylinder #7. Make sure all hoses are in good shape and that the vacume modulator on the tranny is connected ok. If all of this is ok, look for vacuume leaks at the intake gasket.

Anyone else?
Do I have to pull the intake to check for leaks in the gasket?
