hi phil .. i'm Mark ,,,i have a great spark ,,i dont think the fuel is getting thru ,,the ecu is flashing 1 long and 2 short ,,bike has been lying up since 2006 i put new fuel in ,,it started up and ran for 30 seconds then nothing ,,any help would be great
Phil hasn't got back to you yet so I'll just throw this up there for you.
The self diagnoses of the DFI is flashing 1 long and 2 short and as per the chart in the ZN manual, you have a problem with the Ambient air temperature sensor, most likely a problem with the connection to the harness I'm guessing. Corrosion on the connections especially on the low wattage connectors will play havoc. Commuters don't belong in the outdoors but here we are. Low volt, low amp circuits are really susceptible to issues when just a little bit of corrosion is involved. I'd start with cleaning the connections.
Hi Mark, is it a ZN1300 Voyager or ZG1300 you have? I'd try as Kawboy suggested, the ECU plug terminals can get corroded & sometime mis-aligned. Also check the plug terminal for the air temp. sensor. Check across the air temp. sensor with a meter, you should be getting between 2k to 3k ohms when the ambient air temperature is 20 degs C (70 degs F). If you're getting outside those readings then the air temp. sensor is actually kaput. If that's the case you could substitute the air temp. sensor with a 3k Ohm resistor.
hi Kawboy ,,,thanks for the reply ,,,,i dont know which model i have ,,have ,,this is a trike which i have just bought as a project ,,how can i tell which model it is ,,also ,were is the air sensor ,,what does it look like ,, were can i get a workshop manual ,, i see different ones online ,,,,as i dont know the model i dont know if i buying the correct one
