good morning my name is ***** ***** I will assist
does the check engine light come on with the key on???
are there any codes set???
Yes, have check eng light, no stop eng light and haven't put scanner on yet. Will do though
it will help if I had any current codes
is the fuel filter full??? can you check fuel pressure at the fuel pump???
I know if both lights do not come on, no power to the ecm. Didn't know if it was same with one light not coming on. Had this problem last week. Moved some wiring on battery and found broken wire. Seemed to be the prob and now Monday morn doing it again
I assume you re checked that wire and the fuse???
lets start with basics
Yes I have. Cannot hook lap top up.
what is the issue with your laptop??
Not lap top. Id say no power to ecm
did you verify the wire at the battery and the fuse???
did you check the connector for the ecm for the power sources???
