i've been trying to diagnose a no-start condition for a while, ever since i parked my car and it simply wouldn't start the next day. i tried everything on the gnttype.org flowchart, and everything checks out -- the motor is getting fuel and spark. just in case the spark wasn't strong enough, i replaced the ignition module and coil pack -- still no start.
so today i checked the compression and got these numbers:
1: 105
3: 75
5: 115
2: 112
4: 125
5: not checked b/c it's a PITA
i heard compression is supposed to be around 150, so there's definately something wrong with mine. but do you think compression alone is enough to keep it from starting? and what could cause low compression that would allow the car to run fine one day and suddenly make it not start the next? i'm stumped -- please help.
