About ALL I know about your vehicle is that it is a Buick or an Olds. As to what YEAR, MODEL  and ENGINE size, I have NO CLUE.

That's better.

Ok, There is a laundry list of possibile component and or wire failures and to list all the diagnostic information would take many hours.

Depending upon your mechanical diagnostic expertise, I could e-mail you a diagnostic procedure to follow and perform the tests as indicated within the procedure.
