going lean at wot.

2/1 is the det code ain't it..

can you test your stator for weakness or failure..

the below is for my o7 but it gives you an idea on what you can test when you get your specs for your sled...and look for a short in your tail light circuit at the back of the sled or above your brake rotor and in your power valve wiring possibly under your fuel tank..


Peak Voltage Tests
(800/1000 cc Models)
��NOTE: The following tests should be made using
the Fluke Model 73 Multimeter (p/n 0644-191) set to
the DC Volt scale with Peak Voltage Reading
Adapter (p/n 0644-307). For “engine running” test,
use MaxiClips (p/n 0744-041).
��NOTE: Peak voltage test specifications are on the
Electrical Specifications (Individual) pages in this
section.
The Fluke Multimeter w/Adapter can perform the following
output tests.
A. Fuel Pump Coil
B. Injector Coil
C. Charge Coil (1) Output
D. Charge Coil (2) Output
E. Ignition Timing Sensor (1 and 2)
F. Primary Coil Output (MAG/PTO)
G. Lighting Coil Output
��NOTE: Peak Voltage Tests (unless otherwise indicated)
were made with connectors unplugged
(except on primary coil test), spark plugs removed
and grounded, and by pulling the recoil starter
rope briskly.
FUEL PUMP COIL
1. Test between the two orange wires in the fourprong
connector from the stator.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
INJECTOR COIL
1. Test between the two blue/white leads in the connector
harness from the stator plate.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
CHARGE COIL (1) OUTPUT
1. Test between the black/red and green/red wires in
the triple-plug connector from the stator.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
CHARGE COIL (2) OUTPUT
1. Test between the brown/white and green/red wires
in the triple-plug connector from the stator.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
IGNITION TIMING SENSOR (1 and 2)
1. Test between the blue/white (1) or the green/white
(2) and brown/green wires in the connector from
the sensor.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
PRIMARY COIL OUTPUT (MAG/PTO)
1. Connect the red meter lead to the orange/red wire
(MAG) or to the white/red wire (PTO); then connect
the black meter lead to the orange/black wire
(MAG) or to the white/black wire (PTO).
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
LIGHTING COIL OUTPUT
1. Connect the red meter lead to one yellow wire;
then connect the black meter lead to the other yellow
wire.
2. Pull the recoil starter rope briskly. Meter reading
must be within specification.
LIGHTING COIL OUTPUT (@ 2000
RPM)
1. Attach the red maxiclip to the yellow lead; then
attach the black maxiclip to the brown lead.
2. Connect the red meter lead to the red maxiclip;
then connect the black meter lead to the black
maxiclip.
3. With the rear of the snowmobile on a shielded
safety stand, run the engine at 2000 RPM.
4. Meter reading must be within specification

I don't know crap about BD kits but sounds like your extra injectors are not working. Have you ruled them out?

Are you adjusting both the PSI Low and High numbers? Depending on your CR number that is in your box you might not be running enough boost to kick on the secondary injectors at 6 PSI. Check your box. Each PSI is equal to 4.5 CR numbers. Example for the secondary to kick in at 6 PSI you would have to set the CR number to 27. Is your box seeing boost? What are your duty cycles? Sounds like the pump is working fine and it has it's own coil on the stator anyway. At 6 PSI you should be able to run on Primary injectors only depending on your elevation. You could turn up the CR number to around 40 and watch what just the primary injector duty cycle is. Your fueling then would only be adjusted by the PSI Low numbers. PSI low is for adjusting the fueling before you hit the CR number for boost. The PSI Hi works with the PSi Lo fueling ater you hit the CR number. Hope that helps. A little history on how this happened would help as well.

Sams got it bang one money with the new harness I would also check your boost ref hose to the box had one melt last spring it melts just up from the recoil in a weird spot it doesn't look like it gets hot there but it does.
