2012 Sonic 1.8L Engine died while driving P0068 Code

[td11pump]

I coasted to the side of the road and let the car sit for a few minutes and then went to start it again it cranked but didn't turn over. I have a code reader in the car, and it Read P0068. Throttle, MAP/MAF sensor. I had the car towed to Starling Chevy in St Cloud Florida and told the service advisor that the car just died and I read the code P0068. Well I just got a call from the service advisor and he said the mechanic said that the car needs an engine because it had no compression. I said all the cylinders have no compression??? He said that a new motor and the installation would be $15,00.00!!!! The car has a used motor in it and it had 58,000 when it was put in. We also put a new timing belt in and a new water pump. I told the service advisor I would speak with the mechanic tomorrow when I get back to my home.

How is this diagnosis possible??? There was no leaks, no noise or anything unusual from the engine when it just stopped running. I ordered a new throttle with sensor, MAP sonsor and MAF sensor. I will charge the battery also before I change everything.

Any Thoughts and fixes on this????

You didn't hear any noises? Its sounds like something really big has happenened like the timing belt broke and bent all the valves or something

The motor went in at 170,000 original miles on the car. The used motor had 58,000. Again we put a new timing belt and water pump on the new motor. As long as the timing belt didn't break there shouldn't be any bent valves. Again it just lost power and a P0068 code I've never gotten a diagnosis like this before so it's very strange

Yeah, if it were mine I'd want to pull the valve cover off and find out why. If the cams are not turning then the most likely thing is the belt broke.. But then why did it break?

Shouldn't be hard to figure out what happened.
