I'm getting a bit desperate trying to start N62B48 after a swap and partial rebuild/service.
It started a couple of times for a few seconds, but didn't sound like it was running properly.
Mostly it doesn't start. I'm getting the fuel pressure tester tomorrow, but based on everything I can see and hear, I believe the fuel pressure is fine.
I'll be checking for spark and and gonna get a noid light tester.
I'll get a smoke machine as well.
At this point I'm suspecting that I didn't time the engine correctly, but I highly doubt it.
I rechecked everything 10 times, so I doubt there's anything off. At the same time, anything is possible. But some values in INPA, speficially camshafts, concern me. At the same time it may not mean anything. I also scanned DME for errors with INPA, ISTA, bmwscanner, and I don't see any errors that would prevent the vehicle from starting.
I'm trying to figure out if there's anything wrong with my values in INPA and compression.
I don't know what INPA values are supposed to be, that's why I want to check against people with running vehicles.
The same with compression. I tested 2 cylinders, and both are at 100 psi. So I'm not sure if there's anything wrong with my rings/valves (I don't think so) or if that's normal values due to valvetronics.
So all I'm asking is to provide your compression readings and INPA readings from thr DME (ME 9.2)
