Compression

would u consider
70psi on the front rotor
and 55psi on the rear rotor bad compression
and would it cause the car not to start unless u push start it?

That's very poor compression.

Is the battery fresh? - Cranking speed makes a big difference in compression numbers.

Leading plug in, gauge in the trailing hole, WOT?

Warmed up motor? If it's cold, squirt a little oil on the hole before connecting the gauge.
