Normally, press remote: Park & inst cluster lights go on. Fuel pump primes, starter cranks, eng starts. This failure = lights on for 1 sec., then a click, system goes off. (No Fuel pump sound?) NOTE: None of the ‘No Start’ conditions in the User’s manual apply. That manual does not contain tech data needed to diagnose. Do you have tech docs, ie: wiring diagrams, installation instructions, and troubleshooting guides that would help with diagnosis? NOTE: OK again. Could something temporarily disable system?
