Mine does also. told to try a genuine GM delco oil filter (haven't done that yet though) If it subsides after warmup, it is a sticky valve which I am told is too expensive to fix unless it just bothers you too much. Other than that, it's a GM thing and get use to it. :(

Put key forward for 30 min then start

try it counterclock wise

you have an ABS code in the ABS computer. You most likely damaged an ABS sensor. even after myouo fix this you will need to get the code cleared
NOTE: autozone wont be able to access the ABS computer.

does it turn over? or are there any lights on in your dash Take a peek at this site lots of good info

Get the heads repaired or replaced at an engine shop. Also, check for piston damage. Scratched or cracked pistons can be caused when the valves come in contact.

remove head and send to machine shop

Hey there JC

Could be the batterey, but I'm leaning toward cables or terminals. From your description its acting like the battery isn't there, even when you jump it.

Questions:

1. When you jumped it, did the other vehicles engine bog down at all?
2. Do the head lights work?
   
3. Is there any evidence of power? even the dome light?
   

First steps:

• Test the voltage on your battery
• Remove, clean and reattach battery terminals
• Check the battery cables, good connection on both ends? no breaks, wear, anything odd?
• 
  

Comment me back with your findings, we'll take it from there
