BB, took your directive and started the assessment of: lack of fuel / to much air. Taking the path of least resistance, since my knowledge of the gas converter is limited. Purchased 3 meters of vacuum line and started replacing each run then trying to start after each replacement. Sure enough there was one bad piece of hose, issue resolved.

On the light front, narrowed down the associated fuse to the "Brake". Will look to the schematics and see what lies
within that run. If the brake is brake pedal or parking brake possibly and back to a relay, maybe a switch a the pedal.

Thanks JP
