    Need some help with my 6.2 diesel....I am still in the learning stage of diesel ownership and just started troublshooting and learning all I can today..
    heres the problem it is a 1987 chevy 6.2 for the last week or so it was running a little rough and felt a little down on power.Yesterday it stalled it started back up I drove home..One hour later got back in truck started up went about 20 feet it stalled and now is dead..The truck does crank(but does sound different) and the glow plug light does come on...
    Truck has run like a champ up to this..
    Just had oil change in Jan.as well as the Harmonic balancer being replaced...

    Any suggestions ...

    just some things to check= loosen an injector line a little - crank to see if fuel is available?? Also =loosen the fuel tank cap- this will vent system of any possible vacumn-(cap bad) and ive seen this happen before.

    You can try and spray WD40 down the down the air horn to prime the engine to see if that causes the engine to start which would mean you have a fuel delivery problem,,,,,,
