FUEL PUMP STICKY

Had an issue a few times this week where the fuel pump doesn't spin up as it should.

Instead of the high pitched whirring until pressure is reached, i get a very short low pitched grumble, and the FI light starts to flash.

I re-toggle the kill switch and it spins up fine then....

Has anyone had this before, and is it likely the pump is stuffed....?

This pump has about 70k miles on it at the most, having replaced the original when i got power issues due to it fluctuating badly....

I haven't yet plucked it to check the pickup, but even if that was massively clogged the pump would be screaming its head off trying to get pressure.

Or, the pressure filter is beyond clogged, again i doubt that, as i have not driveability issues.....

One owner..... 300,000kms and counting... yes, that much..........

A bit of corrosion on the connector at the fuel pump relay or a weak relay can do exactly as you state.

i am experiencing that exact issue, but when I check the code it is relative to the ignition, and it only happens once in a while....

but some jackass tried to start my bike with a screwdriver.... so i assume its just going to need replacing at some point soon.

Any resolve to your sticky fuel pump? Mine chirps like a bird priming, seems OK though.

Bugger hasn't done it since, believe it or not..... haven't got around to doing anything to it, had my radiator shit itself, so i had to get that sorted....ha ha...

On a side note, the thicker of the two vent hoses onto the bottom of the fuel tank decided to replicate
itself by breaking in 2...got some very thick walled 8mm fuel hose onto that....

...ok...it did it 3 times this morning, cycled the kill switch 3 times and it just "jams" my LED headlight fans drop off a little while the kill switch is on, so the pump is drawing power while this is happening...
I had to turn the ignition off and try again and then it was fine...

I have yet to go through the wiring, but, has anyone any clues on whether a aftermarket pump is truly suitable from 03-07 ?
I know the assembly of the pump is different because of wiring, but the core pump itself is the question....and suggestions of a brand.....

Since this is a more relevant and appropriately named thread...

This is the one I got : https://www.ebay.com/itm/Fit-For-Suz...EAAOSw1r5bZaS2 edit: replaced the link with a similar item from same seller

The pump will fit with the stock fuel filter. You will need to cut the wires to length though and get the round trough-thole connectors (dont know what they are called) in order to connect them to the terminals. Also the rubber cushion on the bottom of the OEM pump does not fit as good on this replacement item. Other than that, the rest of OEM parts fit.
Did not use the rubber hose and metal clamps as they not needed in my case.

It is a no name cheap item, so I cant be sure about quality or longevity ...

I think the seller has removed the listing for specific item... the item I bought had the item number: 254155279003
not sure if it will show something. Sorry !

anyway I have replaced the link with a similar item from the same seller.

they also have several other pumps that fit the sv 1000 :

https://www.ebay.com/itm/Fuel-Pump-F...wAAOSw59JczEWn

https://www.ebay.com/itm/Suzuki-Inta...cAAOSwFTBdZXjm

was also looking at the following item : https://www.ebay.com/itm/New-Intank-...5/121753608654 it is from a different seller and at higher price.

Good selection there..... the dearer one is a litte more plug and play i suppose.....

Gonna pull the pump out this weekend and check everything....
Backflush the main filter ( which i do mean to bypass eventually)
Clean the pickup strainer as well....

Might power up the pump a few times out of the tank and see if it misbehaves

Also, had a thought, if the fuel pressure regulator is sticking, would it cause this, but
assumedly it should just go into bypass if it is blocked....

....EDIT TO ABOVE.....

Took the ignition switch out and gave it a birthday after reading some older posts about the same issue....

Regarding the rotary switch having resistors in it to communicate with the ecu and fool someone trying to hot-wire it....

Apparently if it gets dirty enough, the signal gets all upset, and the ecu doesn't get the signal to trip the fuel pump relay properly...

After i did it, i "think" the whole set-up triggers way faster.....gonna wait till morning and test it again, because that's when it seemed to happen most.
I have my dealer switch on ready to see the response......

2 days later, numerous attempts to find a fault, and all seems well.....
Will keep my fingers crossed that this was the issue...

My fuel pump had been squealing on start up for about a year, recently the FI light had been intermittent then on full. So thinking it was the fuel pump going I was looking around at options... I thought I would see if any code was showing up so I plugged in the switch and got code49. It was to do with the pair evap system not reading with the ecu. About 15 years ago I did the pair mod and wired in the resistor. So I thought I would check that before anything, lo and behold it just crumbled and fell apart in my hands, wired in a new resistor and shrink wrapped it, the bike starts as it should now, no noise or whine..the resistor must have deteriorated for some time but only now it showed up as an error on the dash.. Simple fix thankfully..
