if the turbo is spinning and the compressor is not rubbing the housing, the turbo is likely NOT bad! you have alot more troubleshooting to do before you can say that the turbo is bad. If you have a leak on the exhaust side you won't make boost, a leak on the intercooler side will vent the boost out of the engine also and finally there is a boost sensing line running from the turbo to the injection pump. The truck is also tuned to not fuel hard until it sees boost so if the injection pump never sees boost, then it won't fuel. i bet your boost sensing line is broken or you have a boost leak.
