    Recently while preparing for a full respray, i disconnected most of the loom to get at rust spots at front footwells. Also removed an aftermarket security system which was in the car when purchased. It was faulty. When all of loom was connected again, the car wont start. Fuel pump does not prime, starter wont turn! Almost as if car was armed by the origional factory immobiliser. Any ideas??

    Oh my!!!

    I feel for you on this one mate as it sounds like it could be number of possibilities.

    I'm sure you already have but I would advise you retrace your tracks and check everything over.

    It sounds as though it could be related to the security system???

    I pressume you have power to all the vital componants despite not turning over???

    after another 6 hours of fiddleing with wires and connections, retracing every previous step, I finally traced a block connecter and have the car running again! THANK GOODNESS!! Although i do need different electrical items etc for it, eg cruise control seems to be faulty etc. Were is best to buy genuine parts?

    Also Gotta say!! this is an extremely helpful forum! Im very much a novice with bmw's

    I missed this yesterday, was on the beer! was it the connector under the inlet manifold? If you get a bad connection there it won't start? Unless you seal every plug up well the over spray can create a nightmare with the wiring connections

    hi ronnie
    could do wit a session on the beer aswell funny enough!!! nah the block connection was below the dash on drivers side. Was quite funny because it was a long white block connection, and when plugged in their still was a one wire port vacant! seemed it was not needed but when going over everything else, i came back and remembered and searched finding another (one wire) black plug. Connected into the vacant port and hey pristo!! But just when you say about the engine side of the car,,,,,,,,lol,,,,,,,,when the car is running their seems to be a flutter between tick over and small rev's. I kinda was thinkin the air flow meter or something or Iz this just someting associated with the straight 6?

    check the connection under the inlet manifold, as it can give this symptom if dirty,it's the one where the injectors and such plug in, a round connection IIRC.
    I've seen them with a slight "miss" though.
