Well I turned on the car two days ago and I hear a squeaking from the front of the engine which I assumed was a belt slipping. The car was due to change the belts so I ordered them. However, as I was moving the car onto a lift, a smoking came from down somewhere in the serpentine area. I turned the car off and dissembled air intake and bottom pan to do the belt change and assumed next day I would be able to replicate the issue with a better view.
Well the car won’t run now. I can turn the car but it runs for a half second and then shuts off. One of the pulley bearings must have seized. My guess is the PS pump or the water pump.
Once I remove the belts how to I check the auxiliary component that is broken? I don’t see anything visible to make me think it is one or the other or something else, but I expect there will be some evidence once the belts are removed. Should the water pump pulley and P/S pulley rotate freely?
I agree that the water pump is the likely culprit If so, you'll be able to tell if you try turning it with the belt off. While you're in there, put in some aluminum coolant pipes.
I changed out the belts and check the pulleys which all turned freely. I was also able to crank the car manually with the belts installed. Since the car has ignition and crank, but dies shortly thereafter, I’m wondering if this a high pressure fuel pump issue.
When you were in there did you find where the smoke came from? That seems a critical piece of information here.
No. I had hoped for the same thing but then it wouldn’t restart after I removed the intake to see the source. It sounded like a squeaky bearing. And it smelled like burnt rubber. Which is why I thought it was a belt and pulley. But they all rotated freely.
The car starts for a half a second so I know the ignition is working. I was also able to push on the throttle but then it cuts out.
Theoretically, can I run the car without the SC belt and then also without the driveline belt to rule out the pulleys and accessories?
Thanks. Will check it out. I also need to look at going deeper with the icarsoft. Watching a few videos to better understand how to use it may help me pinpoint the issue better.
No joy. I checked the fuel fuse and also the connectors to the high pressure fuel pumps. I rescanned with the icarsoft and cleared all the codes. I looked everywhere in the engine bay to see if there is any burned connections.

Maybe some wiring damage near the belts? I'm not sure what wires there are in proximity to the belts, but lack of communication between modules and smoke from the belt area is a coincidence I wouldn't ignore.
@shashi27 Seems like an electrical issue if the "lost communication" codes come back right away. Try disconnecting the battery for several minutes, if that doesn't work try @djyankees31 method in post #14 for restoring module communication:

@shashi27 Just to close this thread for anyone else having this issue - was the disconnected air intake (with MAF sensor still connected) the final root cause?
We have all been in these situations before where something big turned out to be something small.
It certainly is frustrating when a car is non-functional but theoretically should be after proactive work. Just consider the havoc resulting from a loose or corroded ground connection.
The great thing about the forum is we can all learn from the members about the various problems that come up (and hopefully the solutions).
Still trying to figure out the "smoking" issue, though @shashi27 as that is concerning.

Well said and thanks for chasing the OP up. I hate when intriguing threads are just left hanging...
