My 02 Honda Civic overheated really bad now it will crank but will not start up. I went ahead an changed spark plugs. Had a compression test done, 0 compression. I was pushing on the left side of the timing belt and it has alot of movement. I also noticed sum coolant leaking from around water pump. Any ideas as to why it overheated really bad and what happened after overheating that has caused it not to start? Any help is very appreciated.

why it overheated really bad:
Faulty cooling fan(s)
Lack of coolant
Faulty water pump
Clogged radiator
Blocked air flow to radiatorWhat happened after overheating that has caused it not to start?
0 compression
Damaged head gasket
Warped or cracked cylinder head
Warped or cracked engine block
Damaged piston rings
Ok, just out of frustration I attempted to start the car again. After holding the gas pedal to the floor it started for about 5 seconds sputtered, backfired through the throttle body then cut off. I tried again and it’s acting like it wants to start but something isn’t there to give it that extra bang. I know 0 compression is most likely 80% of the problem. But why would it have started with gas pedal pressed all the way. Anything else I should replace besides head gasket and getting compression back in the engine?
Whoa… slow down there chippy.
Does the vehicle have clear flood mode?
Suggest you research that.
Next, before diving in to replace a head gasket you should do a compression test on all cylinders ( assuming you only did a single cylinder)
Also perform a leak down test on each cylinder ( you tube videos available to explain the results )
Beyond just replacing the head gasket both the head and block would need to be checked for flatness also inspected for possible cracks.
