See that all injector plug are tight (never remember which models/engines shut down if injector plug is disconnected...), and fuel quantinty valve wires/plug too. Faulty FQV can prevent starting, plus at some point they changed valve concept is it open or closed when no voltage feed.

You have road test active? It does not prevent starting but...
