Have stalling problem with 2000x which sounds like fuel sender unit.Had car towed to dealer because of extended warrenty,he tells me ac drain clogged and ruined ECM ,$800.00,also tells me it is not covererd under warrenty.I find out that the dealer is the one who determines if it is covered.Does anyone know the procedure to dsipute the dealer.Need the truck, am willing to foot the bill if I have recourse.
