Engine Cranks But Will Not Start; General - Buell 2008 XB SERIES Electrical Diagnostics Manual

ENGINE CRANKS BUT WILL NOT START

GENERAL

If the starter will not crank engine, the problem is not ignition
related. See 2.14 STARTS, THEN
The engine may be started and run when the trouble codes
are received using a jumper wire on terminals "1" and "2" of
the data link connector. However, if the jumper wire is removed
with the engine running, the check engine lamp will continue
to flash trouble codes.To stop check engine lamp from flashing
codes, turn engine stop switch OFF.

Diagnostic Notes
Each reference number below correlates to a circled number
on the flow chart(s).
1. Connect BREAKOUT BOX (Part No. B-48115) between
harness and Electronic Control Module (ECM). See
2.6 BREAKOUT BOX.
2. Check battery condition. Perform a voltage test and
recharge if below 12.70 volts. Check battery connections
and perform load test. Replace the battery if necessary.
3. Remove spark plug cable from spark plug.
a. Visually check condition of plug.
b. See Figure 2-29.
TESTER (Part No. HD-26792). Clip tester to cylinder
head bolt.
c. While cranking starter, look for spark. Repeat pro-
cedure on other spark plug cable.
To prevent spray of fuel, purge system of high-pressure
fuel before supply line is disconnected. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00275a)
4. Purge fuel line of high pressure gasoline. See appropriate
Buell Service Manual.
5. Access fuel injectors.
a. Remove right side air scoop. See appropriate Buell
Service Manual.
b. Remove airbox to access fuel injectors. See appro-
priate Buell Service Manual.
6. See Figure 2-30. Plug FUEL INJECTOR TEST LAMP (Part
No. HD-34730-2C) into Breakout Box. Note that cranking
STALLS.
NOTE
TOOL NAME
Attach cable to SPARK
the engine with test lamp in place of an ignition coil can
sometimes cause code P2300 or P2304. This condition
is normal and does not by itself indicate a malfunction.
Codes must be cleared if this condition occurs.
7. If resistance greater than 1 ohm is found between ECM
connector [10] terminal "25" OR "34" and terminal "9", but
not both, the open must be repaired but this repair will not
correct the concern.
If resistance greater than 1 ohm is found between ECM
connector [10] terminal "31" OR "32" and terminal "9", but
not both, the open must be repaired but this repair will not
correct the concern.
