Chart 1STARTING FAULTS
Only refer to this customer complaint after a complete check using the XR25.NOTES
Erase the computer memory using G0** and carry out a road test.
Check there is fuel present
(fuel gauge faulty).
Check the fuel is of the correct type.
Check the hosesCheck no hoses are pinched
(especially after a removal operation).
Disconnect the pipe connecting the canister bleed solenoid valve
to the inlet manifold.
Plug the pipe to prevent an air leak.
If there is no other effect, the canister bleed is faulty.
Check the fuel
Connect the OPTIMA 5800 station to carry out the compression
test and follow the instructions.
Connect the OPTIMA 5800 station to carry out the flywheel test
and follow the instructions.
