side that was not getting had pressure of 150 psi set valves at .005

ran mower pulled plugs left side the one not connected no sign of any fire, right side one that did not get hot had signs of normal use

pulled plug wire and the side would not get hot got hot so what would cause this to happen what are the repairs to fix
