paying the price
check your fuel pressure it should stay at least 40 lbs at least, it can go higher but not higher than 60 if its a stock pump...
odds are its not your icm becuase again 9 times out of 10 its not going to run...
could be your coil yes..check to see if your spark is irradic(spelling) it shoud have a tick on every crank(crank tick, crank tick,crank tick) not crank, crank tick, crank tick, crank, crank, crank) thats bad coil.
if your plugs are fouled they will have kinda gooie black suet on them and smell like fuel...bad plugss...get ac delco platinum( make sure you specify your year of lt1) if you dont have them already
if your wires are bad then the spark will also be irradic or none at all....
to check your opti get a new wire and then take it back or something and a new plug and hook the wire to your opti from cylinder one and then the plug to the wire and crank your motor over...if no or irradic spark then opti most likely is bad or could be icm..
to check if your wires are going bad put a new plug on the end of your current wire and see if its sparking on the crank...
let us know what happens bro

If his optical signals are getting weak, this is exactly what would happen. The car might run like crap, might only be a little bad so it might not be noticeable right away. I simply say check coil/ICM/plugs/wires since they can be checked very simply. The opti gets a little more involved.

ok true true here, but also if spark is irradic with brand new plugs and brand new wires odds are high that its the opti...when it completely stops working it will then have no spark on new plugs and wires...but you can check to make sure your opti is good by doing that test...
new plug and wire, keep it like near the intake or something and crank it...if the spark is irradic then odds are next to most its your opti...but i really dont think it is, could be but hey...
I am going to say that more info would be very helpful... So to the OP... Write us a book if you need to, but describe EVERYTHING it does
