The PCM (or some type of integrated diesel controller) monitors/controls the electronic fuel pressure regulator. Using input data from the fuel pressure sensor (located in the fuel injector rail), the PCM adjusts pressure regulator voltage constantly when the engine is running. Battery voltage and...
The fuel pressure sensor is a good place to start. I am not familiar with the 2012; but, if you can read the pressure sensor value with your scan tool and it is reading chronically below spec the ECU may be vainly trying to crank the pressure up to get it...
LBZ/LMM Fuel-Rail Pressure Troubleshooting While the 2006/2007 LBZ Duramax powered trucks are generally thought of by many to be the best choice when buying a used GM diesel pickup, diagnostic trouble code P0087 is emerging as the single biggest negative for the LBZ/LMM as time goes by and...
The PCM (or some type of integrated diesel controller) monitors and controls the electronic fuel pressure regulator. Using input data from the fuel pressure sensor located in the fuel injector rail, the PCM constantly adjusts the voltage of the pressure regulator to maintain the desired fuel pre...

google "c4 corvette oil pressure affecting fuel pump", the first thing that pops up -- When the oil pressure reaches 4 PSI the oil pressure switch closes and applies power to the fuel pump.. worth a look - you very well could have a faulty sensor or related electrical issue - ???. ...
Next, locate the FPS sensor on your particular vehicle. This sensor is usually found directly screwed into the fuel rail, close to the injectors and the intake manifold. Once located, visually inspect the connector and wiring. Look for scraping, rubbing, bare wires, burn spots or melted plasti...
When doing the cleaning procedure itself, you must use pressurized equipment to feed the solvent directly into the fuel rail while the engine is running. This means you either have to disable the fuel pump and plug the fuel return line, or install a U-tube so the fuel will recirculate righ...
