Low oil, no oil pressure, bad sending unit, wiring, bad gauge,.............
You will need to run an oil pressure test with a pressure gauge.
Bad oil pressure sending unit? Try replacing with a mechanical gauge Excessive engine wear? Do a compression test
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
Check the fuses. Sometimes you have to remove and reinstall them.
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
Hook a fuel pressure gauge up to the shrader valve on the fuel rail.

Start with checking the fuses.
Tire pressure is usually measured with a small bourdon-tube gauge that is calibrated accordingly, often in PSI, pounds per square inch. Sometimes the gauge is a linear spring loaded tube instead.
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.
Use a freon gauge and freon refill can. Connect the gauge to the low pressure ac port of the 2003 Stratus. With the engine running and ac on high, fill the system until the gauge shows full.
