First question - what is the engine oil level? Have you already checked and refilled as necessary? Second question - when was the last engine oil and filter change?

Did you install an oil filter with a built-in anti-drainback valve - to help prevent oil starvation at engine startup?

If the engine oil is to the proper level, and the filter is fairly new - then check for engine oil pressure using a separate pressure gauge. Should be around 40 PSI.

The oil pressure switch should have a resistance reading to ground (with the key off) of zero (0) ohms, and should have at least 12 volts DC across the terminals - with the key on.

Check these various on-line sources; for the replacement parts; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com - to list only a few.

They (RockAuto) list the oil pressure switch from around $18.60 for your vehicle.
