I pulled the fuse on mine cranked it to relive the pressure. Number 5 was bad on my 95 Pathfinder , went to the junk yard paid $5.00 for a used one. When cold my Pathfinder worked fine but drive some were shut it off and get back in would run rough with the check engine light for a few minutes.Checked it with a ohm meter when cold was fine but when it was hot it went past 1m ohms .
