Take it to the dealership if it's under 60k miles. If it's sucking oil, then it sounds like you might have a bad head gasket, which is covered under the warranty. There's been a lot of hinky issues with the 2009 Sentra and #3 cylinder misfires, but apparently they don't want to do a recall on them. It's almost as if they're betting on the problem developing after the warranty expires.
Think the oil pressure switch keeps the fuel pump running once started. Suggest replacing Oil pressure switch. And no it won't effect oil pressure reading when it goes bad. The switch is a safety device. When you roll it over and the oil pressure drops the switch cuts off the fuel pump. Neat huh? Need some good feedback Thanks!
It could, once the engine is running it then keeps the fuelpump running with the oil preasure switch and if the oil preasure drops it can stop the pump,but should start back up unless theres a bad fuelpump relay,
try oil pressure switch the computer provides the power to pump for just a second on start up then the oil pressure switch takes over to supply power the the pump the reason for this is in case you are in an accident the engine dies loses oil presure then kills power to full pump so the fuel pump doesnt continue to have power with the key in the on position
On some cars, if the oil pressure goes to 0, the circuit to the electric fuel pump is disabled. You need to find out why the oil pressure went to 0. It may be a switch or the wiring, but if the oil pump went out, this feature saved your engine.
Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.
NO, check oil pressure module. Bad module (red ligh of check engine on) or a bad cable can interrupt the fuel pump voltage. This is a security to device to induce car to turn off when the oil pressure drop near 0. and to protect the wholee engine
