Won't start, has fuel and spark

Been plagued with a rich fuel trim prob so I chased down a leak to the supercharger gasket, still leaked after the first one so I pulled it apart and put another new one in. It ran before I re- replaced the gasket. I have fuel pressure, spark plugs are wet and I have spark but it won't run. Here's a short vid, I also have a scan from hptuners if interested.

Did you double check everything was plugged back in? How did you determine you have spark?

I believe so. I have a spark tester that you plug one end on the plug and the other in the boot and it lights up as you crank. I did this all at the coil as this motors in a fiero and is a biotch to get at the front 3 cylinders.
 
Pull one of the plugs that are easy to get at and leave it in the plug wire and lay it against the block and see if you can see spark.

I should have mentioned that in my last response, oops. Yeah I did that but I grounded it on the strut tower bolts and yeah there was spark there. And my fuel pressures around 45ish on the guage.
 


Spray some starting fluid or brake cleaner in a vaccum line or unplug the MAF sensor and try again.

Something is not working together, maybe a vats code or something.
 
I tried starting fluid through a vacuum port on the top of the motor(octopus) and no change in the way it's turning over.
 


it can happen like that. the icm maybe throwing the sparks at the wrong time or weak spark.

if you got a junk yard near by pick up a used one and swap it.

the problem with our junk yards is that they want similar to new prices for old crap. Theres one about 6 hrs away and they want $150 for it, I told the guy I can buy a new one from napa for $190, he said thats the best he can do then hung up. Anyone know th epart number for these icm's, I found a couple different ones that look the same but different numbers.
 
try ebay. they are all the same, n/a s/c park ave, montie, regal.

look up your icm on a parts store site, you'll have one part # to go off.

I tried that on one and i got a few different part numbers that they all said would fit and that didn't seem right. But some of the problem is they don't have an option for the supercharged motor.

awesome thanks, i was trying the places i knew, not much in canada. Atleast they had the supercharged option, i didn't think the n/a was interchangable
 
I quickly replaced the icm and it's still not running. At least before it sounded like it wanted to run and now it just cranks over. I will have to test this one as well when I get the chance.
