Engine cranks but doesn't start after replacing CCV

[motorica]

Hi Folks

Hi changed my CCV and did the O2 mod (add vacuum line between manifold and the ccv)
When i finished the car doesn't start , starter works but engine doesn't start.

I did one mistake, when i replaced the ccv i had to disconnect some of the connectors from the engine electrical distribution box. i accidentally swapped evap purge valve connector and oil pressure switch connector.

After the first engine start attempt, i notice my mistake and swapped the connectors.

Engine still doesn't fires,
There are 6 error codes, one of them is 36 main relais ? , and control unit 100

Any help will be appropriated !

Thanks
David

Is this an E39 (what engine?) or an E36 like your sig says?
The E39 has 5 fuses in the DME box, you probably blew one or two of them.
