Check the temperature sensor for the FI computer, as it may think the engine is hot and thus not give any cold start enrichment. Also check if the injectors are actually spraying. If it does, then perhaps the air pressure transducer thing has died. They are obsolete... Can't remember if there is a throttle position sensor that could be faulty. Think there is, because D-Jet is just an electronic carburettor as opposed to later systems that have proper feedback loops. Have fun...
