If the Engine Control Relay output from the RCM fails, the car will quit running and refuse to engage the starter.
Also, if you sit there for 30 seconds wiht the key "ON", the engine fan will warp up to warp speed - due to no tickle pulses from the ECM (since it is not powered up in such cases).
Sounds like a bad RCM to me. Yank it and ship it to DJ or order a new one.
But again, this is based on what few words you typed, it is not a firm diagnosis.
