BMW 520D 2007 - Non start- no high fuel pressure #
Posted by Mark Lamont on May 7, 2018, 6:06 pm Would appreciate some input on this before we push it out the door, I've probably missed something obvious. Car wasn't used and battery went flat, car recovered to me. No engine codes stored (more about that later). Nothing obvious in live data except no high fuel pressure. Good supply of good diesel at 5bar to HP pump, live data reads this too when cranking. Disconnecting IMV takes reading up to 120bar. I have access to a Delphi sealed rail kit, this showed no high pressure from pump, but over 1000bar when dummy actuator fitted so pump is ok. Good 12v supply to IMV and square wave (I'm trying to remember but about 50% duty cycle) so I ordered a new IMV, but old one has approx 5ohm (is this right?) and clicks when given 12v supply. New Bosch IMV is approx 10ohm but all data readings are identical to old IMV when fitted.
