I changed the fuel filter last night in my r53 now it won't start pump cycles all seals in the kit are used. Don'tknow what else it could be. I did have to pull the sending unit up to get my hand onthe lower half.

Thanks in advance...I've taken it apart 3 times to make sure everything was in place

 

Did this a few weeks back, thought it would be an easy thing but it was a pain in the *** and then mine would not start either. I ended up having to have it towed to a Euro car shop down the road and it cost me $200 to have it fixed. According to them I tore a seal, I don't know how because I was careful but all I know is it started fine when they were done with it.

Read & note this particular part:
"Take care to make sure the upper cover is directly seated on the filter element. If it isn’t, the car won’t start."
