wont start

[gsxmad]

Hi. Im having issues when starting my 1400. When i turn on ignition fuel pump runs but the bike wont start.I have to run the pump 2 or 3 times before the bike will start. Just wondering if anyone has came across this before.

What condition the spark plugs,air filter in?

Connect fuel pressure gauge to fuel line. If the fuel pressure is something else than solid 3 bars you have problem in your ragulator, pump or filters.

What year is your bike @gsxmad ?
So k5's had problems with the imobiliser ariel and were recalled.
Other than that
I'd be checking all the plugs in the loom that are easy to get at and the plugs in the headlight and check the fuel filter on the fuel pump.
When was your last service as plugs changed as they don't last forever.
Good luck

Hi Ya.
My 03 bike has similar issues.  I had put it down to my aftermarket MT375 alarm / immobiliser playing up (which it could very easily be, and I will remove the damn thing soon) but as you seem to have the same issue it must be something different!

I was told by a local dealers chief mechanic, that if it isn't the alarm, the ignition switch can cause similar problems.  From memory he said that on some Suzuki models (including the 1400) the switch has two power supplies one of which is controlled to a slightly lower voltage?  If the difference isn't sensed - then the pump won't run and the engine won't start.  I hope that's not a load of BS! I,m sure someone will put us right if it is.

I know this isn't a cure, but I have found the following seems to help.  Flick the Kill switch to OFF, then turn on the ignition switch.  You should then see the CHEC warning come on. Flick the Kill switch to RUN, wait for the pump to run up and she will start.

Good luck

gsxmad, after an attempted star do you get a smell of petrol from the exhaust?
If not it could be the fuel pump has separated, happened to me last year.

If the pump is running I'd doubt it's an immobiliser, the normal two circuits interrupted by them are the fuel pump & the starter.

mjgt's idea about the fuel pump sounds likely especially as you've said two or three runs of the pump can start it.

As for the ignition switch, mine has occasionally not started the fuel pump when turned on. WD40 down the switch sorts it everytime as I think water gets trapped in there. I know some on here have stripped the switch & cleaned it, I've never needed too.

Thanks for all the replies. What i have done so far is took out fuel pump cleaned it and cleaned the tea bag filter. I dont have a gauge to test pressures. Is the any way of testing the pump like how much fuel it should pump in a certain amount of time. Im going to change plugs next week and see if that makes a difference but there is only about 2000 miles on them.

1200 ml in 30 seconds

[KiwiCol]

That fuel discharge rate is misleading??  200ml is just on 7oz not 1.1oz.   I'd think the 200ml volume would be the correct one.


(1.1oz is only 32ml)

[gsxmad]

Thanks lads very helpful, Will try tomorrow evening and let ye know how i get on.

[Beaker]

Check that your pressure regulator has not seperated from fuel pump as per HERE

Good catch @KiwiCol! But also a misread. It's 1200 ml not 200. They should have used quart instead of oz.

[KiwiCol]

Yeah, I did look at the 1200, but figured who writes 1200 as 1 200, with a gap?     And the oz?? who uses that?  14's were never sold in USA.  Just a bit odd.  They may as well put a conversion in there of sheckles & pennyweight as well

We can count ourselves fortunate that the service manual wasn't written by  Chinese and translated by them into english
