That sounds more like an excuse that anything else to me.


everything you have said so far points directly at a bad engine killing delete.

copy the program out of the ecm and e-mail it to me for a proper review of what someone did... good, bad, and downright ugly. Eliminate that as a first step towards solving the other issues, or you will be destined to keep repeating the failures.


ALSO.. an ISX has to be build exactly right.. so it also sounds like you used a bunch of incompetent or under-trained clowns to rebuild it too.

here is what it takes to properly rebuild one...
