Dodge Nitro - fault code P0087 - napessnr

Hi there, about 6 month ago I was having problems starting my vehicle, not turning over quick enough to fire but would start instantly with a jump start so I replaced the battery. When I took it to get the engine management light reset the code was P0087 so I replaced the fuel filter and put a diesel cleaner through it and no problems until 2 weeks ago when symtoms returned ie needing jump to start the car and the fault code is the same, done same as before and great for 3 days then car went into limp mode started again to go out and has been running great again (but engine man light still on ) but had to jump start any suggestions on what I can do now,

cheers, Andy..........

Dodge Nitro - fault code P0087 - Railroad.

P0087 is fuel pressure low. Coupled with the symptoms you describe, the fault could be a poor connection between the battery and the starter motor, or the starter motor itself could faulty, or a bad engine earth. You could also have a worn fuel pump, excessive fuel leak off, faulty fuel pressure regulator, or air ingress into the fuel system due to perished fuel pipe or leaking connection or the fuel filter may not be air tight. Another possible cause could be a faulty fuel pressure sensor. These aren't easy to check because you cannot simulate the pressure that exists in the common rail in order to check the sensor operation. You may be requiring the services of a good diesel specialist.
