I just replaced the engine in my 1997 buick lasabre, with a 2000 chev engine. both are 3.8 engines. The engine that came out of the car has a 2 wire oil pressure sending unit feeding a pressure gauge. The sending unit is bad and the only sending units at the parts places are 3 or 4 wire. no one has heard of a 2 wire unit. What can I do

will the 97 sending unit fit in the 2000 engine? have you tried the dealer? if not, take the sending unit to the dealer and get them to match it to a '97 3.8 hope this helps,

Suggested Repair

Confirm the original 1997 two-wire oil pressure sender fits the 2000 3.8 engine, then take that sender to a dealer and have it matched to a 1997 3.8 unit.

Conversation Summary

The owner installed a 2000 Chevrolet 3.8 engine in a 1997 Buick LeSabre and needs to replace the failed two-wire oil pressure sender that feeds the gauge. Parts stores only offer three- or four-wire units. The expert suggests checking whether the 1997 sender fits the newer engine and having a dealer match the old unit to a 1997 3.8 sender.
