My 2003 trailblazer sounds like a jack hammer when running and has no power, what could this be?

Probably a bad ignition module as it would seem that more than one cylinder would be dead in order to make a jackhammer sound. There are many other possibilities but much more information would be needed.

When my 2003 trailblazer is running it sounds like a jack hammer

Your symptom is vague. You could be talking about a bad lifter or crank bearing. A cracked/damaged flywheel or toque convertor could be to blame as well. Also a broken exhaust manifold or blown manifold gasket could be what your talking about too. Please write back with what you have inspected or tested so far. They sell a tool called a stethoscope. This tool is great to help pin point mechanical noises. Look into one, it may help you. Write back anytime if you have more questions, good luck.

How to pull down oil pan on 2003 chevy trailblazer

Guessing you have the 4.2 liter engine and are trying to figure out how to "release" the oil pan from the engine block as it is on there even though all the oil pan bolts holding on the transmission bellhousing (4 of them) are out and you have everything out of your way like the compressor and differential etc. Take the 2 bolts that were holding the oil pan to the engine block. There are 2 "jack screws" on the oil pan. Take those 2 bolts and put them in the "jack screws and tighten the evenly in to remove/loosen the oil pan. Hope this is what you were talking about as this is kind of a tricky one if you haven't done one before.
