I know some of you know this truck like the back of your hand so hopefully someone can take the guess work out of what's going on here.
2004 Chevy 1500 4x4 Silverado
Originally the oil pressure gauge was pegged but now it goes from being pegged to 0 and back again at randon intervals. It also likes to "ding ding" and tell me the oil pressure is low. The oil pressure is not low (checked it) so this is an electrical issue.
Is this typically a sender problem? chafed wire? gauge cluster?
Thanks for any help!
