Well, at least it surfaced after I changed the glow plugs. I used the Etecno 7v plugs and replaced the GP relay at the same time. The battery was completly disconnected during the whole time. After I completed, I started the Jeep and several times the thing died like the security system took over (5 sec running then died)This happened twice. The jeep started to idle normally and rev up as normal, then I hooked up my code reader, and the dash died and got a "no buss" on the dashboard. quickly removed the reader and the dash came to life and everthing was fine. I changed the battery in the code reader, same thing. took the jeep to the local O'Reilly's and borrowed their scan reader, same thing. Went to a auto shop and with their snap on scanner, they could not communicate. The jeep runs fine.
My scanner is a Actron unit and it has never giving any trouble, but only use it to read codes and erase them.
Any ideas???
