HELP ! No Oil pressure???

Pulled into work this morning - and the gauges light up (engine
and check guages), oil pressure drops to zero. Any ideas? I shut
it right off and I'm going to let it cool off and go out later and take a look.

Are we talking oil pump here???

2001 XJ with 50K miles !

Since the dash warning lights all come on, maybe it's an electrical problem instead of the oil pump. Maybe a blown fuse or loose connector somewhere???

Don't panic just yet.......

Did you check the connector for the oil pressure send unit ?? (Located above the filter) Maybe you got a wire loose... Good Luck !!!!
