650i crank no start
Morning Hans Having a Parts car close by is a major win (providing it hasn't got the same issue 😁) The rev counter gets a signal from the DDE which gets signals from the CPS FPS and Cam sensors the sensor only needs to be loose or a degree out, Test it and or change it (but test the replacement first) As you're so far away I would either get the car transported (my preference), or go ready for anything. That means at least 1 fully charged battery/booster pack. Start with a full scan (INPA/ISTA will show all faults for each system) check all sensors MAF, MAP, TBPS, FPS, CPS. Cam sensors test continuity on the loom for coil packs and injectors. Check/change the fuel pump relay. From your description you say no fuel or spark, all the above will have an effect there. If all those are OK then you are back to the Hope this helps Dave As an after thought make sure the fuel filter isn't clogged. Plus check out the EWS fault you half saw -

650i crank no start
Thanks for the reply Dave. This car is over 5 hours away from me so thr next trip I make needs to be the one I take it home haha. The obf2 I'm using is an mhd tuner off of my 135i with protool. I got it to connect once but stupidly disconnected it. The only code it was throwing was a immobilizer I don't remember which one. Also the conditions of the car breaking down were while driving happened 3 times than didn't start again, at least that's what I was told. So my assumption was a bmw system that controlled efi and spark ignition. As far as the cps if I was reading rpm while cranking would that not rule it out. It also did not throw a code for it when I had it connected. But I couldn't read actual position data since i couldn't connect. The owner replaced the fuel pump in an attempt to get it running so I know the pressure us there but there is absolutely no fuel coming out the cylinders or onto spark plugs. I luckily found a complete part out car 10 miles away from it. So a list of potential problems I could try would be much appreciated. Thanks Hans -

Afternoon Hans Welcome to the Forum I would start with a Diagnostic Scan but then I do have ISTA/INPA on my lap top. Without it I would start by testing the sensors that will effect fuel and spark. Number one Crank position sensor if it is faulty no signal to the DME no signal to the injectors. While testing sensors Fuel Pressure sensor next, while the fuel rail is pressurised is it correct if the pressure sensor is dead the DME will assume no fuel present. Also carefully check the loom to injectors and coil packs not unknown for it to be damaged. Try a Google search for test parameters for the sensors. Also check engine earth straps Hope this helps Dave -

Suspension upgrade
Morning Robin Welcome to the Forum By the sound of things you need a coil over kit for standard ride height with adjustable shocks. Playing with bump and rebound settings should allow a more supple ride, though wheels and tyres are a big part of the overall equation. Bilstien are a well established reliable name that has been around for years so if the kit has been developed for the car should be a good choice, lots of other kits out there with a wild price range but personally suspension tyres and brakes really are not worth cutting corners with.
