    Hi, i have problem with long cranking if the engine warm (one hour after engine stopped). On bimmerprofs is, that LPFP has to fall down from 5 hPa to 4.5 hPa during 15s and HPFP from 150...200 hPa to 5 hPa during 4s (not faster). If i shutdown the engine, the LPFP pressure is from 5 hPa to...

    Hey, I just finished doing a valve cover gasket job, spark plugs and oil change... All good until I go riding and there is 0 boost. I look over the vacuum hoses, replace a few that look suspicious but no difference. Thinking thru the process I recall shorting the + pole of the battery in...

    I recently purchased a 2000 328i 5 speed with 170,000 miles. I am not sure if the fuel pump has been replaced by any of the previous owners. The car is suffering from a no start condition in the mornings and after it has sat for long enough to cool down. After I turn the ignition to position 2...

    I have searched online and learned about the schrader valve on the fuel rail. My question is how much fuel is going to come out when i press the valve? Will a towel or rag be enough to catch it all or is there another method? I am trying to repair a hair line crack in the top of my fuel...

    Looking for help with my project. I Rebuilt most of my engine and figured out where all the sensors and vacuum lines go. Now I'm having a problem with the engine starting. stats, my car is a 2000 328i e46 with a dual Vanos M52tu engine. Compression test. Engine didn't run so it's a cold/dry...

    I have an 87 325i convertible that is continually completely dying at random times. I lose ignition completely and then the car won't start again for an hour or so. I've went through all the sensors (intake, replaced CPS etc) and all connections, cleaned everything,changed the spark plugs...

    Hey guys, today I decided to test my fuel pressure to maybe point me in the right direction with some cold start bogging. My car, though it hasn't done it in a long while, only stalled maybe twice but would come really close to stalling all the other times it did this bogging at startup. The car...

    I was told my fuel pump may have been bad, so i purchased a new one. when i removed my old pump i noticed my line was dry even though i have a 1/4 tank of gas. I then installed my new pump and connected the line but to no avail. I then checked that line again and found fuel was in it and the new...
