That means your ECM is not powering up. Check all your fuses first and then test all the power and ground feeds to the computer and if everything is checked out OK, that only leaves a bad ECM.
Now all this only applies if you have the correct engine, matched to the operating system and this combination has actually run in the past.
I probably should have asked that first.

That's what I was afraid of. If somebody has hacked up the wiring or tried to adapt a different motor, all bets are off. I have no clue what they have done to it.
