have changed the spark plugs, new battery. engine will crank but not turn over and run. Hard to start for the last few days. when running, would run beautifully-no lag, no sputter.
pulled fuel line from engine 3 days ago and turned on ignition-fuel pump would push out dirty/black gasoline. we flushed until it ran clear.

Vehicle: 2003 dodge neon sxt 2.0L

This code is for engine oil pressure you should get a oil pressure tested before replacing this sensor, the specification are @ 3000 RPM 25-80 psi. If the fuel pump pushed out dirty/black gasoline replace and test the fuel pressure the specification are 58 psi. Low fuel pressure will cause hard to start.
