Meaning the starter does not engage? If so, you need to check the wiring from the ignition switch to the starter solenoid.

Also, I can be wrong (have to dig out my LS swap books), but I think the ECU (99) is not compatible to the later year engine due to different crank position sensor (24 tooth vs 58 tooth).
