well your whole situation just sounds like a cluster from the beggining.
can communication? you don't have that. maybe i'm old but no.
but what really gets me is all the guessing.
get to what is really causing the problem and go from there. is it spark?
is it fuel? don't you have lab scopes and other tools to see whats going
on?
as to the charges thats supposed to be written out first.
you left it purty open seems to me and then you complain.
your the owner so you take the responsability and set the limits.
i have a set charge to read codes. then it goes from there.
as to rewireing yer harness in 6 hours just makes me dizzy.
how? did you use new clips and connectors and such? ok, so you say no codes. then you gotta look at things that don't set codes.
really, you need to take it to a proffesional with the proper equipement.
