I was driving my 1987 300E home for from work and it stalled. I coasted to the side of the road and tried starting it. It would start fine but die about 5 seconds later. I popped the hood and removed and put back the fuel pump relay - as I have had problems with the area before. The car then started and ran fine. The next morning the car cranks but does not start. I tried the relay again - this part is fairly new. It does not start. Also I dont hear the fuel pump running.

Thanks.
