1992 Other Suzuki Models No Spark

I have a 92 Suzuki Sidekick 1.6L, 8 Valve, automatic, 4WD with throttle body fuel injection. The timing belt was recently changed after failing. After putting everything back together, there was no spark and no fuel pump run. The check engine lite was on all the time. After replacing the ECM, the fuel pump runs for the required 3 seconds, but still no spark and the check engine lite is still on continuously. I have checked the coil, the igniter and all wiring connectors. Now what coach? Thanks
