I hate it when my first post is a issue with a car.

Ok , as seen in the title the car is a 2006 Sebring GTC convertible with the 2.7.

At 70mph the engine shut off and coasted to side of road.
No coolant temp issue or oil pressure issue , no warning at all
Once at side of road steam came from overflow tank
Engine turns over , but seems very fast as if a broken timing chain
Engine never even coughs , just turns the crank quickly
Crank speed seems to be around 450 to 500 rpm and very smooth (judging by tach)
Cam is turning with the engine as viewed from oil filler cap area
2 days now of no restarting after it was towed home
Fuel pump hums like normal


I will be able to look at the car again saturday , im going to bar the engine over by hand to see if it has any compression and toss the compression gauge on it

Looking for advice here , as i have a hard time beliving it has lost all compression on both banks or lost the timing chain ...perhaps these engine crank that fast and smooth ? last chrysler i worked on was a 91 dodge spirit with 2.2 power ...normally a gm man ....and was a tech 10 years ago in the military .... just doing a favor for someone who just got a job and needs to be able to get to and from work ....i went without work for a year , ill be damned if i let someone else go thru that

 

Pretty unusual for a timing chain to break in that engine. Can't say that anyone has reported that here on the forum. If the cam is turning then the chain's not broken. Could you have lost the tensioner allowing the chain to jump a few teeth? If that happened, the valves may be mashed which would mean no compression. Keep us posted.
Have you checked for codes?

 

po172 and po175 rich both banks , so it lost the ability to burn fuel

 

I have the same issue with my 2006 Sebring. Is it possible that the camshaft and crank shaft sensors may be bad? Or is it the engine is totally gone? Please respond soon...

 

I fixed the timing belt and it did start but ran extremely rough and then died out. I reset the timing and it will not start. the engine just spins with no fire. Please help. just bought this car and really hoping that it is not dead.

 

Check the compression.

 

If the compression is off, how can that be resolved?

 

The valves must be in good shape for the engine to develop compression. If there is no compression, it's a sign of possible significant valve train damage. The only resolution is to pull the head(s) and repair the damage.
You mentioned a timing "belt" in your post although this thread was about a 2.7 liter engine which has a timing chain rather than a belt. Assuming yours is a 4 cylinder engine (which has a belt), you could have bent some valves if the timing needed to be "reset" which would result in no compression.

Don't assume that's the problem without running the tests because it's a big job and an expensive repair.

 

began troubleshooting it . as my helper was turning the engine over i watched in horror as the water in the coolant bottle jumped every time the engine turned. compression test confirmed we at least have blown the headgaskets ...i hope the heads are ok
