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.

if you're curious how this is going for me, here's some strange news.

i got all ready to start cracking on it after work today, picked up some tools i left at the parents place, bought a new multimeter, etc. while i was at work yesterday, i went on celicatech and printed some wiring diagrams, trouble code guides, everything i could find. i decided to start by pulling fuses and resetting the ecu.

i put them back in, and just for sh!ts and giggles i tried the ignition. keep in mind it's been almost two days since i last tried starting it and the battery is run down to almost nothing.

the thing actually started.

second try, because it only turned over a couple times the first time. it cranked slow because of the low battery and it was idling very low (i think <600 rpm) but i gave it very gradual throttle and it spun back up to normal idle and i actually drove it around for 25 minutes to recharge the battery.

i'm impressed to say the least.

i'll have to wait until tomorrow morning to try it again and make sure, hopefully it wasn't just goofing around with me.

still makes me wonder what made it not start for two days, but i'm not going to complain now.
