Sounds like you might have a wiring issue.
Unplug, clean and replug everything in site, check the battery is good too, low batter voltage can upset the ECU. Mine regularly looses headlights because they are full of muck, quick wiggle and they come back.
Once you are happy with wiring make sure the fuel pump is running. I dont know how on a zook, but you should be able to get the fault codes out of the ECU
