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.

stu - i'll check the ignition fuse first thing.

itchy - i checked that all the plug wires were set, both battery terminals, engine ground, etc. i did assume that the fuel system is cool b/c it hasn't been acting up at all (sputtering, rough idle, stumbling at throttle). i will absolutely check the few things you suggested, starting with spark. i'll need someone to crank it while i hold the plug wire, right?

i appreciate the help, i'll post up my progress.

thanks alot!
