To be fair, the bike didn't die of its own accord I think from memory we turned it off each time. That said, there was rather a lot going on - I had a panicked seller who was seeing what he thought was going to be a £2500 dissipate. It did pop and bang A LOT! Not ruling out ECU!
Pump was taken out in June last year and it's not turned a wheel since.
OK, so I have found the Fuel Pump Relay. Clipped next to the ECU.
When I hook up the multimeter, there is 12v between the yellow/red and brown/white. Nothing between the other two.
The spade connectors look a little dirty/nasty.
The relay is new (previous owner - I've ordered new from Suzuki) marked CA1a-12V-A-5 and ACA1215 MO1
When the ignition is turned on, the relay clicks, the LED in tacho lights solid for two/three seconds and the relay clicks again and the LED then blinks and the LCD reads FI. The pump does not run/whirr/prime.
Should there be power across the other two lines?
Will keep digging.
OK, really worried now.
Have just been reading the Suzuki Genuine Workshop manual. It says 'Removing the battery terminal of a running engine is strictly prohibited. The moment such removal is made, damaging counter electromotive force will be applied to the ECM which MAY result in serious damage.
Yesterday the seller took the battery off and rigged an external battery. He took it off whilst running. I asked him how it still ran without a battery. We then started it again, and I think he disconnected. Then, we put the (bike) battery back on and I can't remember if it started. It was soon after this that the FI LED flashed etc.
In the manual, C41 is:
Fuel pump relay circuit open or short
Fuel pump relay malfunction (its new)
I do wonder whether the ECM was fried yesterday.
Any one in the UK got a 32920-02FA0 ECM I can borrow/for sale to test for running?
As the Goblin King said: 'That'd do it'.
Cheapest I've found in the UK: https://www.ebay.co.uk/itm/Suzuki-TL...edirect=mobile or https://www.ebay.co.uk/itm/SUZUKI-TL...edirect=mobile.
TBH at that price I'd be tempted by one if I had the money... Getting harder and harder to find reasonable priced components
Have purchased ………..
I'll update when the unit lands.
Any vehicle with a computer should not have the battery unhooked while running. The battery serves as a "filter" to prevent voltage spikes from frying things. WE old codgers used to unhook the battery to check whether the charging system was working, we had to unlearn that.
While you're waiting on the new computer you might want to check the white and yellow connectors under the left ram air cover for corrosion. It's a common problem. Clean the connections and apply a bit of dielectric grease. Might prevent other gremlins form popping up.
"The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."

ECM has been dispatched but not home until Friday. I should have a fuel pump relay, fuel pump, starter relay and ECM waiting when I get home!
I messaged the guy I bought it from - he says he started it weekly without an issue.
Thanks for the tips on the wires. What do they feed?
Finding a lot of loom gremlins. Sense I have a lot of repairs and upgraded to do!
