TDS 2.5 fuel pump non delivery

[moggyroo10]

hello, i hope somebody can help me get my new toy on the road. its a 2.5 tds estate. my problems started after i bought the car as a ropey runner, it tried turning over but was hydrauliced, i thought an injector had overfuelled and filled a pot. i left the car for a couple of weeks and when i came back to it the battery was totally flat. with a good charge in the battery the car would not even attempt to start off the key , i was advised that the chipped key had probably lost its memory and would need re setting. on to of this the engine turned out to be totally shot so i have fitted 525 tds engine, the car still wont turn off the key though all ign lights come on. i have swapped the pumps so that it has the 325 pump on but although the pump is sucking deisel it all goes back to tank if i short the starter and spin it over. any ideas please, surely having a flat battery cant mean going to a main dealer which would probably cost more than the car is worth

you did not specify the year model of your car, but check the starter and fuel pump relays.

regds for your reply, when the car was stood and the battery went flat it had the key left in the ignition and i have been told by a bmw service manager that this will have wiped the key chip memory and that without a spare key theres not a lot can be done to retrieve the coding

I had a 325TDS at my shop with exactly the same problem. I couldn't get around the problem but someone else is looking at it and if they fix it I will post it. Good luck.
