'06 530xi e61 - no start issue - with spark

[JC1970]

Hello Everyone,

Thanks in advance for your help - we have a no start situation on our 2006 e61/n52.

Car was driven through high water, and has not started since.

- started did need to be replaced, so that has been done successfully with the new starter actively cranking.

- was not hydrolocked

- no codes at the moment. We only have the small basic code reader, so...

- crankshaft position sensor connector socket broke. Since there was water in the sensor socket, sensor was replaced along with a new pigtail.

- left DISA was broken so that was replaced

- spark is confirmed by removing spark plug and grounding it to engine block. Did this on 2 cylinders.

- fuel at fuel rail pumps when cranking

- no smell of fuel from the cylinder when a plug is removed

Could this be a bad K6327 injector relay? I have not tested it yet, nor have I tested any of the injectors. Also, have not been able to locate the injector relay itself. None of the diagrams that I've seen so far show the exact layout of the box under the cabin air filter for the 06 530xi e61. FYI the box was dry with no sign of any water.

Any help would be appreciated!
