OH NO celica won't turn over, advice needed Options

[uberschall]

hey everybody. i'm in a bit of a hurt and i hope somebody can give me some insight.

my 5sfe didn't start today. i've NEVER had a problem with it before. the starter runs but the engine won't turn over. it's damp and rainy today, for what it's worth. it has a full tank of 91 octane, the battery connections are tight, and all the plug wires are connected properly.

with the gracious help of my neighbors, we tried push-starting it several times, but as soon as the clutch pops, the engine makes a horrible diesel-decompression sound and the tires just skid (maybe because of the wet ground)

i'd like to replace the plugs, wires, coil, dizzy, etc. but i'm hoping someone can help narrow it down. i will do my best to provide any additional info if needed.

thanks.

i checked every connection i could. i live in an apartemnt complex, so i don't have a garage...and since the weather has been rather damp and cold lately, whatever is causing the issue is rearing it's ugly head regularly but not predictably enough that i could get it to my parent's place (read: garage) to isolate that variable.

i had aaa tow it to a nearby shop earlier this afternoon and rode my bike to and from school. the killer is that i have two jobs and 3 classes that i can't default on in the meantime...so there aren't alot of opportunities for me to devote great amounts of time to figuring out what's wrong with it.

i would have liked to figure it out myself and do the repairs myself, but right now having a car that does what i need it to is more important than the pride.

the car hasn't been in the shop since i bought it, hopefully it turns out okay.

thanks for the input everyone, i'll keep posting.
