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.

okay, moving along then.

i pulled my efi relay. i'm supposed to be getting continuity across the blades as shown on top of the relay?



across the silver ones (horizontal in the picture above), right?

i read a resistance of 76 ohms across those terminals but the continuity buzzer reads "open".

i pulled the thing apart, and it looks pretty clean inside (no corrosion or anything)



i also pulled the starter fuse to check as a comparison (the starter is working fine) and i don't get continuity across the same terminals on that, either.
