if you did a compression test it generally could only be 2 things. One, spark plugs, Two, plug wires. I dont know maybe you did something wrong? I would just take the plugs and wires back out, and then put them back in....like start from scratch sorta deal.

Are your plugs hooked up in the right order ..starting with te coil closest to the passenger side
It should go 4 1 2 3 Cyl 1 is closest to driver side

Because you crossed some spark plug wires is why it happened.
Don't feel too bad, people do it all the time.
