car wont start still... new opti and plenty of fuel pressure

I am getting no spark to my spark plugs...

i just installed a brand new opti and nothing changed, i have a new MSD coil and ICM wiht less that 200 miles on them.

What else could cause no spark to the plugs???

THanks

just did coil and made sure the the opti was installed right and it was.... icm is pretty new and coil wire is pretty new (both under 2000 miles), and checked all fuses... none were blown.

and still no spark... how often do PCMs go out, that just doesnt seem like a common thing!

Is there any spark coming out of your coil. check it the same way you check your plugs.

Is there any power (12v) going to your coil wires, The wires that plug into your coil on top. If your not getting power to the coil it wont fire thus wont send spark through your distributer
