LS170 will start and run in service position. In run position -nothing. The EIC lights up and belt is buckled, but it won't start in run. If the parking brake light and the seat belt light is flashing/on in the run position and buckled up,does that mean there is a problem with either of these 2 systems? Should there be voltage from the seat belt/ seat system that I could check? Any other ideas how to diagnose this? I do have a repair manual downloaded, but there seems to be 2 different wiring schematics, and neither one seems to be totally accurate. Thanks!
