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.

your going to have to determine what element your missing.
you need spark, fuel and air for combustion. you should have air... check if you fuel system is functional and the fuses that run. check your ignition system and fuses that run it.

pull a spark plug wire off and hold it about a half inch from any grounded piece of metal in the bay and watch for an arch. if it does then you have spark.

for the fuel start by making sure the fuel pump turns on. I forget how quite a stock pump is so im not sure if you can just listen for a little humming.

hope you figure out whats wrong. the more details you supply the easier it is to figure out whats wrong.
