It is the brown / pink wire that I measured and it was 4.4 volts with the ignition on. I also measured the CA purge valve connector and it was 4.4. So if it is the ECM Relay where is it and how do I replace it.

Try swapping ECM Relay (#7) with the Cooling Fan Relay (#5)
(Make sure that 5, 6 & 7 are all the same type - this is a specific relay - should be a Bosch 0332 014 112)

Quick question - is your neutral light illuminated? - not whether transmission is in Neutral - is the LIGHT actually on? (Solid, not flickering)
If swapping the relay makes no difference try raising the side-stand

That relay is interlocked by either neutral or side-stand - if in gear (or thinks is, i.e. neutral sensor is not on or flaky!) and side-stand down, it will inhibit the injectors.
Raising the side-stand, the ECM does not care whether in Neutral on not - no interlock.

Ok I will try those tests later today. I have to attend kids sports for a few hours and then back to the bike. I'll let you know.

The three relays are not Bosch they are all Hella Brand but they are all 01RA001. I swapped them out and measured at the Cal plug and it measured 4.4 volts still. I put the side stand up and it still measured 4.4 volts at the injectors. The neutral light is a solid green all the time. Just so you are clear the fuel tank is off the bike with the pump disconnected. As I said before the wire to the pump measures 12 volts and it pumps huge.

I also measured the volts at the fuse panel in the main power slot and the fuel pump slot and they all measured 12volts. The fuses were fine. I measured for resistance.

The 4.4 is probably coming back through drive side of injectors; ignore fact is 4.4 - if not 12v the relay is not turning on

So does that mean the relay is broken? I did swap out the two as suggested and got the same measurement. I would suspect that both of them are not broken.

I would concur.
Either
a) no power to input pole (unlikely since same source to Fuel Pump Relay)
b) No power to coil positive (again unlikely, the coil + and input pole share same source)
c) No enable to coil negative via the ECM.

The enable for the coil is a ground sink to ECM on the yellow/brown wire - that should go 'low' to turn on the relay after ignition is powered and ECM sees 12V on the Green/Red wire to pin 69

This is also inhibited by the aforementioned side-stand/neutral switch arrangement; however the other possibility - if there are no broken ground or power wires, is bad ECM.

I am always reluctant to suspect ECM (especially just a sudden unprovoked failure) however as it is usually something else.

Are you SURE there is no ground block on your bike???
They are normally obscured by bunch of foam .......

Make sure the ECM connector is clean & non-corroded.

I will start pulling all the connectors tomorrow and clean and replace. I'll insure the grounds are all good and retry all the measurements for vots etc. What is a ground block?
