When I press on my accelerator my car will not move. Even if the car is in neutral the engine will not rev. If I manually depress the throttle it is very sluggish and will not rev unless it is pushed all the way down.
I am new to the diesels and just drove my 79 300td across the country - it ran fine, although it is very slow to get moving. I am afraid I will get rear-ended trying to move in traffic Now, it will not move at all, it idles fine.
HELP!!!!!!!!!!!!!!!!!!

Does it seem to be "starving" for fuel? Need more details. Almost sounds like your fuel filters need to be changed.

When I press on the accelerator it stumbles a bit, but the rpms still will not rise much above idle. Sorry, this is my first diesel, so I don't speak the language very well yet.

Well i'd start by checking and changing my fuel filters..main and inline... see what happens from that point.

Some of these cars have rubber connectors and mounts in the accelerator linkage. I'd start with checking the linkages.

Happy Motoring, Mark

Thanks for the help, I believe I broke the ALDA, and that is when the problems started, however the car has always been extremely slow off the line. The car has not sat dormant as far as I know. It drove great from Minnesota to Salt Lake with the exception of slow acceleration.

Breath. Try and breath. I did a search and see that you fiddled with your ALDA and possibly broke it. Before or after? I ask for the benefit of others. I don't have a turbo, and do not understand an ALDA's operation enough to know if it is a factor.

Had the car been driven much before your road trip? Did this start happening near the end of a tank? If the car was dormant for long awhile condensation could have formed and the newfound warmth from an extended run probably caused an algea bloom. You'd be amazed how rapidly that stuff can grow. As Tom opined: clogged fuel filters. There is a clear plastic fuel filter on the driver side of the engine. Can you see through it, or is there nebulous, dark, diesel impeding matter inside?
