Hi, my name is ***** ***** I am at your service to assist with your VW problems. Welcome to Just Answer.
If you test the lift pump it should deliver between 6-7 psi when the engine run. If you test this with a pressure gauge and you find that the pressure is not at this spec then you will have to replace the pump.
I do not think there are problems with the high pressure pump as then the engine will not start.
I hope this information will assist you but if you need more please do not hesitate to ask.

Hi Randy,
Wow it would seem there is a problem in the motor. What color is the smoke? If it is white it's over fueling. Blue/black is engine oil. A broken ring/s will cause a bad misfire ruff noisy operation.
