Hey, I usually try and get by on my own with most things but I'm hoping someone with previous experience of this might be able to help out a little.

I was up at the track last week and, after the last session, I was low on fuel (fuel light just began blinking as I rode the bike round to the van).

I came home and put my rear indicators and license plate back on, checked they were working and went to start the bike to check all was ok. The bike wouldn't start. I assumed that it was because I was too low on fuel and decided to let it go. I had some mods to do and would put fuel in the bike and take it for a test ride when they were done.

I put my HRC throttle and '07 1000RR kill switch on early this week. I followed the advice in the threads here and hooked up the wiring as follows:

'03 600RR <------------------> '07 1000RR
Yellow/Red <-----------------> Yellow/Red
Black/Yellow <---------------> White/Green
Black/Red <------------------> Black/Red
Black/Green <----------------> Yellow/Green
White/Black <----------------> White/Black
Black <------------------------> Black
Blue/White <------------------> Blue White

I popped the battery back in tonight, hooked it up and put some fuel in the bike. I put the key in the ignition and turned it to on. Here's what I get:

Kill switch set to run:
No fuel pump sound, FI light on, Oil pressure symbol, Red HISS LED, Red Error LED. On pushing the starter button, the engine tries to turn over.

Kill switch set to off:
No fuel pump sound, Red error LED, Oil pressure symbol. On pushing the starter button, the engine tries to turn over.

Both headlights work, turn signals are ok, brake light/tail light is ok, as is my plate light and my clocks are working (obviously). I've checked the BAS fuse in the fuse box. Side stand is up (bike's in neutral anyway). The fuel indicator is also working (giving a correct reading for the amount of fuel in the bike).

Unfortunately, I don't have a multimeter but I think now's probably a good time to get one! I'm really hoping this has just been caused by me being a dumbass :retard:

Thanks in advance for any help you can offer.

So in both positions the fuel pump does not prime? Have you checked all the fuses?

Also when you tried start the bike before the 1krr killswitch, was the pump priming?

What do you mean by tries to turn over? Does the motor spin at the normal speed but just not sound like its trying to start? Or does it turn over really slowly?

And yep, time to invest in a multimeter...

Well here's an interesting one (and I feel very stupid for this!).

I checked the FI fuse, the BAS fuse, the side stand switch and the kill switch. Nothing.

I was racking my brains, trying to think what I was up to when I wes getting my bike street ready again last Tuesday. I then remembered that I had gone to get some new keys cut (they look to be the same euroblanks slowboy has for sale). I then thought, wait a minute, I've only been using the new keys since this problem appeared.

Turns out it was a HISS related thing and the bike starts fine with the original key.

I noticed there have been a lot of "fuel pump not priming" threads recently. If any of you have recently started using new replacement euroblank style keys then maybe try the old key one last time, for nostalgia's sake! I feel so stupid! I presume the key does have some kind of HISS related gubbins in it then? I suppose, at least I have myself a multimeter now...

nice find, but yea, for HISS you have to get the keys programmed, if it works like american encoded car keys, not going to be a way around that

we dont have HISS in the states...

Ooops! Thanks man. As the saying goes, you learn something new ever day!

HISS is a system that uses a transponder in the key and a transmit / receive coil on the bike...

The coil is energised by the ecu with a carrier signal, which the transponder chip in the key then uses for power and replies with a modulated carrier signal which is then fed back to the ecu for it to verify... get the wrong code and none of the outputs from the ecu get turned on... this includes the fuel pump, injectors and coils.
