919 blade ecu
Posting this for a friend who does not have the internet.
Have been helping him with wiring his car up, all went well untill the point of getting the engine to run.
Fuel pump runs ok, power to ecu, cranks over but no spark.
First thought it was the ignition leads has he has got suppressed cable and the ohm meter readings where double what the manual said. The leads have
since been changed to copper reading now as manual says but still no spark.
The only thing we can think of now is the the ecu is no good.
Anyone got any ideas.
Or a cheeky request anyone got a spare ecu for a 919 engine that we can try, the one with a throtle position sensor.

Stupid answer but have you made sure the engine is in neutral and the sidestand is linked out etc

As Tony says the sidestand and neutral switches both need to be switched (join the wires) for it to fire. Also on 98/99 engines there is a pink wire
that runs to the ignition barrel. In the ignition barrel is a resistor which needs to be there as a kinda anti theft device (so it cant be started
without the ignition barrel), if the certain voltage isnt present on that wire then it wont start. You can get around this with a 390 ohm resistor
connected to the pink wire and an igniton feed tho.

On the blade there are 3 cut-outs:
Neutral
Sidestand
Clutch depressed (on '95)
Correctly shorting them all to earth bypasses the "safe-start" and it should fire.

Also worth noting is the 97-99 919cc blade engines had an immobilser fitted. Check for a pink wire coing from the ECU.
If it has this you can use a resistor to generate a small voltage (3.9V I think) to sort this out. If your ECU hasd a pink wire let me know and
I'll post the bypass instructions.

Thanks guys
The neutral and sidestand are shorted to earth, will check on the pink wire and keep you informed.
Mine is a 93 engine and did not have the stated pink wire so only had to short sidestand and left neutral in circuit.
Did not know 919 engines had an immobiliser fitted.
