2000 5.3 oil pressure sensor in 1990 K5 Blazer All, I’ve tried researching this but can’t find anything concrete. I swapped a
2000 5.3 into a 1990 K5 blazer. The oil pressure sensor plug from the K5 blazer is identical to the one on the 5.3. I put a new sensor specific to the 5.3 on the motor. Question is both original sensor and the LS sensor the same OHM range? Will the sensor work with the stock gauge?

If you're not sure the engine is going to make pressure you use a mechanical gauge the first start.
If it is a known good engine and will make pressure, you will also know if the gauge is good on the first start.

I would be shocked if the 5.3 sensor would work with the 1990 gauge.
Mechanical or electric gauge plugged into the 5.3 would tell the tale. You buy a cheap Equis? gauge at any parts store.

Just FYI, I broke out my handy dandy pump
sprayer/priming thing and pumped the motor up with oil. It does work, 30 psi on the sprayer and gauge. Thanks for all the information above, it was very helpful.
