Hi people !
I have one e36 that"s goes to one garage to change the clunch and never work no more !
sintomes

car crank but no start , I connect the DME on the table and establish conections width autocom , but in the car no way !
I made a junp wire on the fuel pump and the pump work"s
the only think that"s is freeking me is that in the car no comunications at all !
20 pins plug are ok ! I check all the wires !

what could it be ?? the white relay ??

thank"s in advance

If you really did check every wire in the car's plug for the DME, including the power supply and paying extra attention to the ground points, then you might want to cut the diagnostic line from the DME's plug in the car and connect autoCOM directly to that...if still no connection then you must have missed something, if it's fine then something's wrong with the diag line.

But usually when such a car mech job is done on a car and doesn't start afterwards, then it's usually because someone forgot to put back a ground wire, that's why I said pay special attention to the ground pins.
