84 300SD Will not start (replaced fuel filters)
I read up on previous posts about how to handle an SD that won't start after changing fuel filters (by cracking the injector lines to bleed out air) and everything worked perfect. The car started right up. But the next morning she would not start. ? I have repeated the air bleeding on the injector lines a few times and get fuel up to the motor one injector at a time but still won't start.
PS - I also upgraded to the new style manual primer pump but the new one doesn't sound like it is pushing fuel - only air.... Thanks in advance for any advice you guys might have. |

Unless you poured some diesel in the big fuel filter, you've got ALOT of purging of air to do. And I mean alot. almost to the point that you should take the glow plugs out so you can crank and crank and crank,,,

Did you loosen the round knob (the primer pump handle) before you started pumping it? I'm not absolutely certain, but I think all the pumping will be in vain if you do not open it up (turn counterclockwise). If it started once and then failed to start again, it surely sounds like air in the lines. I've needed to prime mine numerous times when fooling with the fuel system and have always been able to pump it up, rather than cracking lines at injectors. Maybe I'm just lucky, but so far a little pumping (then retightening the pump handle) did the trick. Of course filling the large filter with fuel is highly recommended. Good luck.

Well it looks like the issue was 1) Air in the filter (lesson learned) 2) A bad set of glow plugs. Once the plugs were replaced she started right up. Thanks for your advice!
