RE: 87 300TD no power
Definitely a fuel related issue there. Check both your fuel filters (and possibly the tank strainer), but you'll also need to investigate the ALDA device on the injection pump for proper function. The latter is typically the cause of lackluster acceleration in MB turbodiesel engines. These units need to hold at least 10psi pressure to function properly, and many have developed leaks over time. They can also be adjusted or shimmed to increase fuel quantity under the boost curve, which will dramatically improve your off-idle acceleration.
