Hello,

I
recently bought a 93 Park Avenue Ultra. Just had the crank pulley
damper and seal replaced on it. When driving it home, the oil pressure
gauge reads zero while idling or slowing down, but rises to a normal
level while accelerating. The oil pressure was normal before this. What
could be causing this? Thanks!

Check the oil pressure with a mechanical gauge,if normal replace the oil pressure switch. If abnormal could mean oil pump and/or engine bearing.
