U United Firing Order

Pull all four plugs, have someone crank the engine while feeling the compression air as it blows out the plug holes. Then you will know for sure what the order is.
 
On a 4 cylinder there is either 1,2,4,3 or 1,3,4,2. so if one does not work then try the other
 
nothing hard to figure that out. remove plugs and get #1 cyl. on tdc on compression. plug the spark plug holes with those plastic protectors from hyd. fittings. then turn engine overr slow by crank if possible and watch what order they fly out.
