VN v6 engine into kart. Wiring help please

[kietalibby]

Hi all, I have put a vn v6 into a kart and I am trying to sort out the wiring and seem to have come to a dead end. So I am looking for some help.

Listed below is what I have done and found out.

- Conected up the standard loom.
-As there is no dash I have just used a couple of togel switches for the ignition barrel. (lots of excess wires and plugs)
- Fuel pump is hooked up and starts and stops with the relay. Running an efi pump and tank from an excel.
- I have run a test light on the injector and seems to me they are ok. light flickers on and off when the engine is turning over.
- I have tested the spark plugs and they are creating a spark
- I have taken off the air con unit and the power stering units. currently do not have a belt running arround it
- exaust oxygen sensor is conected.
- There is one plug that I can not seem to work out in the engine bay. Picture below.
- It seems like it is trying to fire on 1 cylinder only

It is puzzeling me in that there seems to be spark, fuel and air but no go.


Any help is apreciated.
Thanks

thats plug is for cruise control.

have you hooked up the check engine light and diagnostic plug? checking error codes would help.

I believe I have hooked up the diagnostic plug. As I said it has no dash so no I have not hooked up a check engine light. Which (of the many) wires should I use to create a check engine light? How do I check the error codes?

Guys, I have hooked up the check engine wires to a light and found that it comes on and stays on from acc, ignition and when I try to start it. As I have said I am a complete novice, what does this mean? How do I rectify it?

Any help is apreciated.

Thanks

it will come on and stay on when the engine is not running.

you need to bridge pins 5+6 in the diag plug, and then turn ignition on, and watch for the light flashing.

if you do a search for checking error codes, it will give you a list of what they mean.

Great thanks. I will give it a go and report back

More to the point, i think we all want pictures !!!

Guys, Just had another look to try and diagrose the problem and have noticed that I do not have a diagnosis plug. Can you tell me which wires relate to the 5th and 6th pins.

On the wiring diagrame I have it does not have a specified diagnosis plug but does have a DFI module? where would the plug / wires be in the wiring loom?

Will it make any difference if I do not have a plug?

Thanks

Theres a White/Black trace wire that goes from the ECU connector terminal D6 to the diagnostic connector, this wire needs to be temporarily earthed out to put the ECU into diagnostic mode.
