I have inspected all related wires to ECU I have A 2003 GL 1800A Goldwing I have a service manual that indicates to me power and ground to ECU are as follows B21 BLK/YEL wire and A12 BLK/YEL wire are the 2 power wires have Battery voltage The grounds are A8 GRN wire A9 GRN wire and A20 GRN wire all are good grounds. But I have no FI light when you turn the key on and fuel pump really will not engage all wires related to relay are good the ECU is supposed to ground the relay but does not I can manually engage relay fuel psi is 55 good but still won't start. I think I must be missing something I have tested all 3 ignition coils and are good I have been an Auto tech for over 40 years mostly GM but this one has me stumped. Everything points to the ECU But I purchased a new one from Honda Same result no FI light and no start

Unfortunately my info is limited on this model here but someone else here may be able to assist further on this.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete
