Joey Mack Posted March 18 Share Posted March 18 Ok.. check the wires for the EUP's they are known to rub against the engine block and short out. Be very careful with the 5mm screws. They do NOT come out. Just loosen them and slide the terminal back and up and out. I recommend taking all 6 sets loose and stretch the harness out.. it seems like it's an 8-2 code. The second number represents the EUP # Quote Link to comment Share on other sites More sharing options...
eric787 Posted March 18 Author Share Posted March 18 ok would that mean cyl 2? and is that the second one back from front of motor. and any resistance specs i should be aware of? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted March 18 Share Posted March 18 Yes #2, I don't have specs.. the EUP may not be the issue. Quote Link to comment Share on other sites More sharing options...
