Okay finally had a day off... 1. Fuel tank-clean 2. All filters-new 3. New fuel lift pump 4. New squeeze bulb primer 5. Bled small filter and low pressure side of fuel injector pump I started the engin and kept the RPM at about 800 for 3 minutes to warm up (grey smoke comming out of exhaust and it feels like the throttle position is more forward than normal) As soon as I try and advance the throttle it dies. I try and restart it just dies again. My last step will be to replace the fuel injectors(?) but I am at a roadblock. The silver lining is I am now VERY familar with the fuel system on a 2GM!

I am scared to admit this in this croud but I'm a diesel mechanic. Have you done a fuel flow test before and after the Injection pump? using the decompresion valve crank the engine over for 20 seconds. if you have good steady flow then check after the pump. if both injectors are getting steady shots of fuel then its the exaust. if you have fuel problems after the pump its an easy removal and get it rebuilt. they break springs and cause low injection pressures.
