I finally got the motor swap on my 1981 VW Caddy 1.6l diesel. Change fuel filter and fill with fuel and also fuel pump. Gave it a little starting fuel and it cranked right up and ran about 30 sec. Hit the starter again and ran for about 30 sec. During this 30 sec I pulled the choke and the motor died right then. Can start the engine every time and this happens. During this running it is really rough. Also I let the glow plugs do there thing each time. Do you think the fuel pump is letting to much fuel in ?????
