Good Afternoon, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you, so sorry to hear about the issues here on the Cavalier. I know how frustrating it can be to deal with a no start. Now just so im clear how long did the car overheat for? Currently does the car crank but not start?

okay thank you, \*\*\*\*\* \*\*\*\*\* can blow [head gaskets](/topics-head-gasket-chevy/) pretty quickly so i fear that you are not starting due to low compression. i would recommend we get a compression test done in order to ensure the [engine](/topics-engine-chevy/) is internally sealing well. if compression checks out fine we can begin to test that all the injectors and [ignition coils](/topics-ignition-coil-chevy/) are working correctly but i suspect this will be a mechanical issue.

How can I diy compression chexk

My 2012 Scion tC will over rev when I'm trying to accelerate.
If your clutch is slipping (https://www.yourmechanic.com/article/how-can-i-tell-if-my-clutch-is-slipping) you will be able to hear the engine rev, and the tachometer rise without any apparent acceleration of the car. It tends to happen in the higher gears because that is when the load...
