5.9 Magnum help needed

Ok, so I turn the key to the on position(right before starting it) then I turn it off and then back on and then back off and then back on right? And you said it was the check engine light that was suppose to flash? :/ I didnt get anything when I did that. Just the annoying buzzers as usual. If its not the timing chain im all out of ideas.

Yes thats actly how to do it but you do it quick but when you go to "on" pause a moment each time just to let it notice its at on.It really should flash something,either someone bypassed it or the computer has an issue.Did you check all the spark plugs and wires?If its firing and getting "enough" gas it either way out of time,getting no enough fuel or the plugs are completely shot.
BTW does the check engine light come on when you just turn the key on,it should if not the bulb may be shot.O'reillys has a rent-a-tool program and you can use a ODB11 reader.As BillGrissom added the fuel injectors are controled by the computer and if the computer has gone bad it will not send all the signals correctly.
