X3 with no Shrader valve to check fuel pressure? intermittent no start

[Bucketlist]

Sorry if I posted this in the wrong place but I couldn't find an X3 forum.
I am chasing an Intermittent no start problem on my 2007 X3 3.0si with 60,00 miles. We have had this car for 4 years with no problems. The last few weeks it intermittently won't start but turns over good. Can cycle the key a few times and it may start but sometimes has no engine power until I restart it another time. Ran a test with Bavarian Technic software and had crank sensor code. I changed the crank sensor and the problem continued. Want to check the fuel pressure but this x3 doesn't have a shrader valve on the fuel rail. I now have a repeating 2A38 code which I think is sluggish vanos. Will this cause a no start? Thanks in advance! Any help will be appreciated!

The Fix:
After lots of research and too much money spent my 2007 x3 is fixed.
If you have an intermittent no start or other running problems there is one thing you should check which could save you some time and money. The eccentric shaft sensor is inside the valve cover and sometimes gets filled with oil causing all kinds of intermittent running problems. This sensor is easily inspected by removing the vanity cover and pulling the plug. If the plug is full of oil the sensor is most likely your problem. This is not an easy or cheap replacement. Here is a link to a very good writeup on this:

Update: 2A38 Valvetronic, actuator: sluggish or open circuit.
I have decided to order this actuator from our host and replace it myself. Will update in a couple of days.

Update: Installed Valvetronic Actuator, not fixed. Back to square one.
