Get the code read, then give us the po-numbers.
Rowefast is right, u need the code #'s Some auto stores will read them, than tell you what they mean for free
what if it wont read the code
Usually it would be the power to the ALDL plugin that is not working, usually runs off of another circuit for power, check fuses,
Did u take it in for codes to b read? Did they tell u they couldn't b read? Did they given u a reason?
