No Start Condition
We have had reports of a no start condition on several motorcycles with Delphi fuel
injection. The problem occurs one time and does not return, so is difficult to
diagnose. When the condition occurs, a P1010 code - missing password, is
normally set. There have been a few reports of a P1009 code - incorrect password
also. We are still investigating the cause but it appears the turn signal module did
not get a complete message from the ecm at ignition ON so the engine starts and
stalls or cranks but will not start. If you receive a call from a customer with this
condition, or have one in your service department, try removing the ecm and
security fuses, wait a few seconds and reinstall the fuses. We have found this
"reboots" the turn signal module and the motorcycle will then start from that point
on. The historic codes will remain for 50 starts or until cleared.
