94 F250 Pre power stroke will not rev
 

My 94 F250 Direct injection Turbo diesel will not Rev up at all, it smokes like its getting way to much fuel? I am lost here, I just put a new Map sensor on because my tuner gave me the code indicating that it was bad. Still doing the same thing. Any ideas?

If its direct injection its a powerstroke. Do you have a scanner?

Its the international, i don't have scanner that works for my year, I have a programmer that runs diagnostics, but it showed the map sensor was bad, I replaced it, but still no change

The powerstroke is an international engine. Is it an idi as in indirect injection or the powerstroke which is a direct injection engine.

Direct injection
 

My truck is definitely direct injection, F vin, if that helps anyone out!

If it's smoking white, and smells like fuel, most likely a fuel problem.
Maybe clogged filter, line, etc.

If it's black, you're getting too much fuel for the air available.
Could be a severely clogged filter, bad turbo, etc.

You may try seeing what it does if you unplug the icp sensor.

All set the truck back to stock and remove the programmer.
