Tricky crank no-start problem

[80stech]

Good thing it didn't start if the oil pump isn't working. I doubt that is all of the problem though. You proved oil pressure to the vanos doesn't help with the no-start and the compression is what's needed to make the engine run, not oil on the rings. Oil pressure has no place in a no-start guide though I did run into that once but it was a combination of problems which led to the fuel pump not running because of low oil pressure at times (GM product though.)
