Drove car home, parked overnight. Next morning, will not start. Tests show timing belt good and aligned. Camshaft, crankshaft turning. Pistons moving. Has spark. Radiator pressure test shows no bleed down. All 4 cylinders read zero compression.

So if the vehicle was running fine the day before and not now and nothing happened to it, I suspect something went wrong with the test because it is unheard of to loose all compression on all cylinders overnight.

Here is a video and a guide on this. Review this and make sure this is what you did and then we can retest it. If you have zero compression then you will have a leak which is why we need to do a cylinder leakage test next to find out where the compression is leaking.

Let's start with this and go from there. Thanks
