I just bought an 83 300D and was driving it home and it just quit on me. I had it towed home. One of the injectors was loose and leaking, I tightened it up and replaced the fuel filters. The small one was nasty. I replaced the worn Fuel Return lines and it still will not start. I checked the air intake...maybe a mouse or something got in there??? No, it is clear all the way to the turbo. I have no idea what the next move is. I was getting up on the interstate and it only got up to 40 and then just loss power...like there was no fuel...and then to idle, then died. Any suggestions would be greatly appreciated. Scott
