Bmw e60 n47. Wont start, no fuel in the fuel rail. Have changed various sensors - now there is fuel in the fuel rail but not enough. Thinking it might be the hpfp, how can I check if it's faulty?

Have you checked for injection pulse or compression. Will it start if you spray carb cleaner in the intake?

I have exactly the same issue!

spray starting fluid in the intake if it tries to start you have a fuel problem if it doesnt its in another place if it tries on starting fluid you need to back probe the injector wires all the pink or red wires will be hot when the ign is on all the others are pulsed grounds from the pcm while cranking check for the ground pulses if your getting them then the spider is bad.

SOURCE: wont start. has spark, fuel to fuel rail, new TPS,

Check injector pulsation at injector harness with test light, with key on, disconnect harness at injector check for voltage, then reverse test light at battery and on the other pin check for ground pulsation while cranking engine, should have pulsation, if none bad computer, injector pulsation control by computer.

The error P1130 and P1131 is for the fuel trim and lean fuel mixture respectively. This tells me that this may be an issue with the air fuel mixture or its reached its limits in compensating for the incorrect mixture. You could try to clean out the intake first using carb cleaner spray or tuner spray to clean out the intake and the MAF sensor which measures the air that comes in. Check also if there are leaks or gaps on the air duct found between the air filter and the intake manifold and the intake plenum. Leaks would cause the system to get an incorrect reading. If it were a faulty sensor you should get the error code for the sensor and you may have issues starting the engine up.

Check also the vacuum hoses which may be loose or cracked that needs replacing or refitting. This is also a common cause. I also do not rule out the possibility of the fuel sensors going or starting to go bad. The PCV may also need cleaning or replacing.

With all mentioned items go check first the leaks of the intake system and the vacuum lines as these are found to be common. Some leaks or cracks are minimal but is crucial to the sensors.
