I start my van fuel gauge shoots to top 10 sec. later drops to empty
on 2002 Oldsmobile Silhouette

van drives normal no hesitation in throttle resonse ???is it a bad wire ???

Asked by for the 2002 Oldsmobile Silhouette
Yes bad connection or bad fuel sender assembly. Due to the fact that the fuel gauge goes all the way up and back down, it sounds like the gauge is okay.
