Re: how much compression (xisda1)
80 that doesnt sound good at all 
... psi should be at 184 max and minimum is i think 164 or something like that... 28 variation between cylinders.....the cause of this could be warped head and possibly blown head gasket like you mentioned.

Re: how much compression (xisda1)
I retested the compression it was at about 120 in all four cylinders would that cause it not to start?

you waited 1 MINUTE to bump your post. wait longer. one a day.
and it sounds like you arent doing the compression test correctly, so i would look somewhere else as to why it isnt starting.
start with the basics
remove the spark plugs, see if they smell like gas
if they do smell like gas, dry them then put a spark plug in the end of a spark plug wire, ground the plug against somewhere like the shock tower bolt have someone crank the engine, look for a spark.
thats gonna check for gas and spark. only 3 things are needed for the engine to run, gas, spark and compression.

Re: how much compression (Kamin)
yeah, there is spark and fuel and 120 psi so is that compression too low for the car to start or what? Or could it be the timing is off?
