brucet

Hi, I am new here, just ran across the forum searching google
The problem I am having is, when you turn on the key, the service engine soon light does not come on, it does not come on at all
I checked the bulbs and fuses, all are good
My truck failed state inspection because of this
It is a 2001 2500HD 4X4 crew cab

I hope this gives you at least an idea, if not, I can do my best to answer any questions

Thanks in advance
Bruce
