Bank Angle Sensor/Fuel Pump Not Priming??

2000 cbr929; ok so my pumps not priming...i checked the fuses (under the seat by the battery) is there more elsewhere? none of them were blown. I asked the local mechanic what it could be and he sent me on the bank angle sensor route. ive been all over forums looking up the correct way to bypass it but i just keep getting confused! (YEAH I KNOW ITS NOT SAFE!) there is a white, green, and red wire coming out of it. i cut the outside two wires (red and green) after the connector and spliced them together.....should i cut the white one also?.....or do i leave it and connect the R/G wires. i tried it both ways soo far and NOTHING! am i doing something wrong,. or is it something way different? he also mentioned a fuel cut off relay,.,,.,.what do i do with that???? Please let me know! OR even an educated guess!!

You cut the wires?
Did you check for continuity of the bank angle sensor to determine if it's working correctly?
Apply 12V power to the fuel pump relay and listen for it to click or check for continuity on the secondary circuit.

Have you tried connecting 12V power directly to the pump to confirm it is working?
Bypass the killswitch as well as they wear out if you use them regularly to kill the engine instead of using the ignition switch.
I assume the instruments are lit up as they should be?
And the engine cranks okay on the starter motor?

Re: Bank Angle Sensor/Fuel Pump Not Priming??

FUEL PUMP
INSPECTION
Turn the ignition switch ON and confirm that the
fuel pump operates for a few seconds .
If the fuel pump does not operate, inspect as
follows:
Open and support the front end of fuel tank (page
3-4) .
Disconnect the fuel pump 3P (Black) connector .
Turn the ignition switch ON and measure the voltage
between the terminals .
Connection : Brown (+ )-Green (--)
There should be battery voltage for a few seconds .
If there is battery voltage, replace the fuel pump .
If there is no battery voltage, inspect the following :
-Main fuel 30A
-Sub fuse 10A, 20A
-Engine stop switch (page 19-18)

-Fuel cut relay (page 5-60)


FUEL CUT RELAY
INSPECTION
Remove the fuel tank rear bracket and ECM cover
(page 5-89) .
Disconnect the fuel cut relay 4P connector, remove
the fuel cut relay .


FUEL PUMP ASSEMBLY

Connect the ohmmeter to the fuel cut relay connector
terminals .
CONNECTION: Black/White-Brown
Connect the 12 V battery to the following fuel cut
relay connector terminals .
CONNECTION: Brown/Black-Black/White
There should be continuity only when the 12 V
battery is connected .
If there is no continuity when the 12 V battery is
connected, replace the fuel cut relay .


-Engine stop relay (page 5-89)

Connect the ohmmeter to the engine stop relay connector
terminals .
CONNECTION: Red/White-Black/White
Connect the 12V battery to the following engine
stop relay connector terminals .
CONNECTION: Red/Orange - Black
There should be continuity only when the 12V
battery is connected .
If there is no continuity when the 12V battery is
connected, replace the engine stop relay .

-Bank angle sensor (page 5-88)
Connect the bank angle sensor 3P (Green) connector
and place the bank angle sensor horizontal as
shown( flat part up ), and ignition switch ON .
The bank angle sensor is normal if the engine stop
relay clicks and power supply is closed .
Incline the bank angle sensor approximately 60
degrees to the left or right with the ignition switch
ON.
The bank angle sensor is normal if the engine stop
relay clicks and power supply is open .
If you repeat this test, first turn the ignition switch

OFF, then turn the ignition switch ON .

-ECM (page 5-89)
Disconnect the ECM 22P (Black) and 22P (Light
gray) connectors.
POWER /GROUND LINE INSPECTION
Connect the test harness between the main wire
harness and ECM (page 5-7) .
Connect the test harness (page 5-7) .
TOOL:
ECU test harness
07YMZ-0010100
(two required)
GROUND LINE
Check for continuity between the ECM test harness
connector A9 terminal and ground, between the
A20 terminal and ground, between the B1 terminal
and ground, and between the B12 terminal and
ground .
There should be continuity at all times .
If there is no continuity, check for open circuit in
Green/Pink wire and Green wire .
POWER INPUT LINE
Turn the ignition switch ON wire the engine stop
switch in RUN position .
Measure the voltage between the ECM test harness
connector B6 terminal (+) and ground .
There should be battery voltage.
If there is no voltage, check for open circuit in Black
/White wire between the ECM and bank angle
sensor/relay .



hope this helps.
