When you do a compression test, you have to push the gas pedal to the floor so the throttle is wide open. Also, pull the fuse for your fuel pump and unplug the distributor when doing a compression test.

Here is a good video on how to do a compression test.

Okay just re-did the test and got 91 for cylinder 4. 98 for cylinder 3. 90 for cylinder 2. and 104 for cylinder 1.

The min psi on each cylinder should be ~140 where ~180 is excellent.

This goes back to an earlier question. Did you remove the cylinder head and replace the head gasket? This would involve removing the timing belt and pulling the top half of the engine.

Or did you just remove the valve cover and replace that gasket?

I removed the head gasket. I also replaced the valve cover gasket yes but to answer yes I did remove and replace the head gasket. I did not have the cylinder head serviced though. And to answer your previous question awhile back the issue for me was oil and coolant was mixing that is why I replaced the head gasket.

I have read that it could be the rings losing pressure so I am going to try putting some oil in the spark plug hole to see if the pressure goes up. This will check if it is a bad ring. I just don't understand what could be doing this as everything was running fine but with leaks before I started working on it.

After added oil to spark plug tubes my readings for a pressure test is now 108 for cylinder 4. 113 for cylinder 3. 110 for cylinder 2. and 119 for cylinder 1. So I got much closer and higher numbers after applying oil to all the spark plug tubes. All of my rings couldn't have possibly gone out right? My oil is working just fine as I have removed the valve cover to verify this and oil was squirting out just fine.

Are you sure it's gasoline and not coolant shooting out of the spark plugs holes when you do the compression test? Worse case scenario, the head may have been warped all along, causing the new head gasket to fail.

I am fairly certain it is gas as it has a strong smell of gas. Would the head gasket have had an opportunity to fail if I have yet to get it running with the new head gasket in place? I still can't get it to start. Is there anyway to test the coolant idea shooting out of the spark plug holes? I am almost certain it is gas.

That's correct

Low compression + not having the cylinder head serviced likely means the compression loss is due to a bad seal with the head gasket.

A leak down test would help out in this case. I'll post a link below.

My guess is that you will have to remove cylinder head and get it serviced.
