Hello Patrick rayome on my 2000 3.0 mitsubishi eclipse the firing order is different. From every body else I guess it is 1 3 5 on the back and 2 4 6 on the front but on my cap on the back it is from top to bottom 3 5 1 and the front is 4 2 6 form top to bottom it won't run any way that I put them it's in time I've replaced crank sensor I've replaced the distributor plugs and wires cap and rotor button 02 sensors. And I have triple checked my work any ideas

burned valve is likely the culprit.... or bad rings.... hook air up to that cyclinder one at a time.... and listen where the air is escaping... be aware that the motor will rotate till the piston is at the bottom of it's rotation. if it's a burned valve you will have to remove the head and replace it but somewhat easier job then replacing the rings. darn almost forgot.... it can also be a blown head gasket.... same procedure but you might need a brush and some soap water to test for an air leak at the side of the head. when you are done spray some wd 40 on it to get the water off so the spark plugs do not arc.
