Fuel pump not arming

[phil24_7]

If it's not priming when I have confirmed power to the plug, it can only be the pump at fault, either because it is gummed up or because it is blocked.

I will remove it from the bike tomorrow and clean it with carb cleaner to try to free it up. Then I will flush it through with fuel to try to avoid damaging the internals with the carb cleaner!

did you use the return path on the plug as an earth or the frame/battery?

[phil24_7]

Both, same results both times!

cool. i know i'm being awkward but it's best to chase every avenue before stripping anything off a bike when it might be something else.

I know, I'm slightly annoyed that I stripped the whole back end to have a dig at the alarm!

Now I'm really confused. Of the myriad reasons there are for a non-functioning motorcycle an alarm is just one possibility, and far far from the most common.

The alarm seemingly worked perfectly, disarmed when you wanted it to, the bike switched on and turned over when you pressed the button, at what stage was the alarm doing anything other than it should have?
Despite the assertion, bike alarms are rarely connected directly to the fuel pump, on dual circuit immobilisers, (as Datatools are), one circuit cuts the starter circuit and the other the ignition or the ignition/fuel injection system. Of course this may also disable the fuel pump as part of a fuel injection system but it would be apparent as none of the electronics would function, not just the pump.

I still can't see what prompted the suggestion of alarm failure.

Def datatool alarm.

When I sold my sv with the exact same alarm, my mate had it sat for a little while and it generated this exact fault.

We tinkered with it and got it going but a couple of weeks later when he sold it, it did it all over again!

Daddyjob bought this bike and removed the alarm and as far as I'm aware didn't get this problem again which must be almost a year ago now. Give him a PM

Well the alarm has always had little niggles like going off for no reason immediately after arming and beeping 3 times in service mode (which indicates a possible hot wire or ignition activation, when in actual fact, neither of these things have happened) so it is not beyond the realms of possibility that the alarm has started to go faulty. Modern electronics aren't built to the same standard as electronics of yesteryear.

I know that alarms like the datatool have 2 immobilisation circuits, 1 being starter (which was working) the other (as stated in the fitting instructions I believe, as well as many on-line resources) is the fuel pump. The bike was started 2 months ago so unlikely to be dead fuel so therefore unlikely to be the fuel pump. With the amount of problems people I know have had with alarms, that seemed the most logical fault. Once this was discounted, I moved to the next logical fault...the fuel pump. Then I had to find out how this circuit worked so that I could test it.

Sid, I know your an electrical genius, I however am not. I'm ok at them but no expert. Also, as you have deal with this type of problem before, you already have experience of it, whereas this is the first time I have dealt with this type of fault, I shall be better informed next time.

Stu...defo not the Datatool...defo fuel pump!

There's a good chance the K5 GSXR one will fit, think someone like D'Ecosse or GrahamB or someone else who is wise in the ways of science was using one.

They're annoying bags of sh*t that break all the time.
