I have a 2001 pontiac firebird with 132,000 miles(I travel quite a lot) and I have been having problems with my oil pressure. My oil pressure constantly drops and then will pick back up and drop again. When I was working on my car I ended up having to change my relay and water pump and flushing my heater out. My car worked fine for about 2 weeks. Now I have no oil pressure and my check gages light is on. I am sure that my oil pump has given up the ghost. I called different auto parts stores and the places I spoke to had no information on that part or could not get it for me. I called another place and was told that the oil pump is built in the block and I would have to buy a repair kit. I just want to find out if this is correct before I buy it.

Before you replace the pump replace the sending unit--If you loose oil pressure the engine will quit because the fuel pump circuit goes through the oil pressure sw

Suggested Repair

Replace the oil pressure sending unit before replacing the oil pump. Loss of oil pressure can also shut the engine down because the fuel pump circuit runs through the oil pressure switch.

Conversation Summary

The owner of a 2001 Pontiac Firebird with 132,000 miles reports oil pressure that fluctuates and then drops completely, with the check gauges light on, and suspects a failed oil pump. Parts stores said the pump is built into the block and requires a repair kit. The expert advises replacing the sending unit first and notes that the fuel pump circuit depends on the oil pressure switch.
