You running any kind of Power Commander or anything else?

 

[Bumblebee]

When was it ran last?

Did anything happen when it was running (did it sound odd or anything)?

There is something interrupting the power...is there any sort of an immobilizer on it?

 

[202mphbusa]

I will repeat for the 100th time
Check the voltage AT THE COIL STICKS while cranking

Gen I ... Cranking ....seems like no spark..Help! | Busa problems

So I continue to battle my BUSA. I am currently using a 2006 Busa as the engine in my Trex-copy 3 wheeler. I have been working on this for a couple of years dealing with all sorts of things. The last thing I had to figure out was the shifting mechanism. All the while I have been (periodically)...

No nothing different but it sat up about 8months an I did find bite marks where I put the the black tape on the wire going to ecu an coil an it was one on the negative side going to tip over sensor

Check all your wires to make sure one is chewed through...or grounding out due to the outer casing being chewed.

Make sure your battery leads and terminals are very clean, might be worth it to use a little emery paper on them.

I most definitely did

 

[202mphbusa]

I most definitely did

AND what was the reading?
If you are getting 12v ish

no codes? you should get spark
coils are simple 12v in
ECU controls grounding
check the 4 wires between the other side of the coil sticks and the correlating ECU terminals with the ECU unplugged next

Ok checkn an gettin new readings on the coil will the reading post different if I hook the battery up the charger while cranking

Nothing is ate thru but a couple are skinn back on the ground side

Electrical issues are my worst thing to deal with so I feel your pain...

I can sort of see why people buy new bikes every few years once the warranty comes to an end.

you checked all fuses?

 

[mjizzle454]

Yes all we’re good

If the ground wires to the coils are exposed thru the insulation to the copper wire, AND if the exposed wire is touching a ground(frame, engine etc) they may be shorting to ground and therefore having no ground switching at the coil, this is a possible cause of the problem but unlikely to be causing all 4 coils to stop spark at the plugs.

 

[mjizzle454]

Upon my inspection I found this could this b the reason for no spark it was not completely broke when I found this can this be but connected back if I pull the pin out

White wire goos to Crankshaft Position Sensor
Take the Service Manual and look at Wiring Diagram

 

[Vanishing Point]

Scheme K3-K4 but it's the same

Ok so if I but connected back I should b good
