Chevy Blazer -97 Does not run

Anyone have a good answer what to do with a blazer that won´t start?

What happens:

-Startmotor rotates, but the bastard will not start....

Everything (ligts locks wipers etc.)are normal but fuel pump and indicators(check engine , airbag symbol) does not come on.
The plugs have no spark either.

I´ve checked:

-Fuses
-Cables between CPU and the rest of the car ( big connector under plastic cover )
-I have 12v up to the fuel pump relay.

Feels a bit worrying that all indicators are "black".......

Any good ideas anyone, before I tow it to the junkyard.
