Usually black smoke means too much fuel or unburned fuel. As mentioned, could be a bad injector. How long has this gone on and what was it doing before this all started? Maybe some fuel injection cleaner in the system might work....

it hasn't been very long it was running find before but now when I start the engine it continues to run until it runs out of fuel it also runs at high rpms I have loosened the injectors and only one will leak any fuel I have been able to get a mex mech. to come out to look at it but this is mexico and you don't know if they will show up I will try the injector cleaner what brand would you recommend for diesel
sorry it has been so long but have been having problems with internet
what I found was the injector pump had a screw come loose and it got in to the piston springs and caused a lot of problems was able to order the parts and I'am now waiting for them to get here to baja so that I can rebuild the pump
thanks for your info this site has been very helpfull
thank you
