'85, 300D turbo diesel (straight 5) recently conked out and won't start. Car started sounding flooded or not enough gas going down the road and then eventually cut off and it won't start back up. (even with battery cables). Doesn't seem like it would have anything to do with the
G plugs since it conked out while driving. Everything turns but it won't crank up, just keeps acting like it wants to start but won't catch. Replaced both fuel filters to no avail, could be the fuel pump I suppose, but don't know their reliability. I'm at a loss being a new diesel owner (and don't know too much about diesels anyway), will gladly take any input. Thanks.

Have a friend pull back on the stop lever and try again.

Pump up the manual primer. Pay attention if it leaks when pumped (or if leaks elsewhere) and if so replace.

First loosen an injector line at the injector and watch for fuel coming out when you crank engine. Or take return line off injection pump and try pumping your hand primer pump till fuel comes out there. In otherwords establish if you do or do not have fuel available. It will not run without it.

Thank you TMAllison and barry123400, the ideas sound promising and I will definitely try them! Have a good one!

When were the fuel filters last changed? If you don't know the answer change them both. I would also suggest unplug the brown vacuum line that attaches to the shut off valve on the backside of the IP and see if it starts.

Good Luck
