Truck Repair/2004 cummins isx


where would you start troubleshooting no oil pressure already changed oil pressure sensor Thank you

I would take out the sensor and replace it with a gauge at the sensor that takes out the electrical from up to your dash. if you have no pressure there your going to have to drop the pan without having the serial number to look it up. should have a pressure relief valve. Another thing you might check is ive had a incident where the pickup tube was to close to the bottom of the pan and wouldn't suck up oil.
