Drove for 65 miles no problems parked and tried to start but get this message lots of noise runs poorly, chain tensioner? Did a hard reset ng ?? At opinions wating for tow.

 

You need to read the OBDII codes and post them and not what they tell you they mean the real codes.

 

Turns out my diagnosis was not to far wrong, one of the upper timing chains snapped and took out the tensioner, when my mechanic took it apart found other tensioner cracked, replaced both chains and updated tensioners.
I was VERY VERY lucky that there was no damage to the engine I guess the fact that the failure occurred at a startup rather than running may have helped.
Hope this will be the last repair this year, so far
1)front breaks complete
2) pull instrument cluster replace all lamps
3) repair seat control box
4) fuel pump and water pump
5) expansion tank
6) new battery
7)chains and tensioners
