Engine on GMC 01 Yukon will not start

This problem started suddenly w/o warning. Started missing more and even died a couple of times. Seemed like when it was running rough, the more you push the gas peddle the more it bogged down and would die. Send black smoke at one point. Replaced fuel filter, cleaned MAF sensor, no change, replaced fuel pump, no change, replaced f/p relay @ fuse box. Tried to receive error code and no error codes show up on Actron AutoScanner..At this point engine just turns that's it.

A/C blows only hot air in 2004 GMC Yukon XL.

Is it properly charged? A check of the pressures would be a place to look next.

2005 yukon denali, a/c worked fine until battery died

Get the climate control computer relaced or reprogrammed. There is a good chance that when your vehicle was jump started it fried the climate system.

Yukon was running and all the sudden died started up service engine light came on idles super low in gear and dies unless you put foot on gas and brake if stopped

easiest & probably cheapest way is to run into an autozone or Pep Boys & get them to scan fro codes for free & go from there. Get back to us with code(s) unless it's a simple one & part is right there at store to fix it.

Check engine light and stalling seems to be slipping out of gear.

You said the check engine light is on. Have you had it scanned? What is the code number?
