2000 Nissan Sentra 4 cyl Front Wheel Drive Manual 83920 miles
I replaced the fuel pump and noticed that the gas was returning to the tank just as fast as it was going in so I replaced the injector pressure regulator and it still acts like it is getting no gas if I pinch the return line to the tank it runs fine. I bought a Actron OBD 2 scanner and I get P030 Misfire detected changed spark plugs did not help P0171 too lean bank 1. I do not know if it is the injector or what.
On the Monitor it says
oxygen sens mon inc
Oxygen sens ok
fuel System Mon ok
comp component ok
I have never noticed that the fuel pump works all the time when you start the motor but when you turn the key to get ready to start it pumps for a few seconds then stops but the minuet you crank the engine it pumps and the engine runs for a few seconds then dies and will not start till the pump stops
then start up for a few seconds like running out of gas.
It has plenty of pressure in the line.
I am stumped.
have the same problem?
