I recently purchased a 98 Daytona t595 and can't get it to start. I have fuel, I have spark, I have air. Nothing. Even shot ether directly into the box and again, nothing. I'm at a little dumbfounded here. The bike worked fine when I first got it. Rode it for a couple of days, no problems. Went out the third or fourth day and it wouldn't turn over. Wondering if anyone has had this problem or any insight on the matter. Anything woud be appreciated. Thanks.

I had a problem as thus described with my 01 Suzuki Katana, being both bikes are carbed I am thinking the same solution might hold. Does your bike back fire when attempting to start it or when it was running? I am thinking it may need a new set of plugs, was the bike sitting any length of time prior to your purchase. As much as this might be a drudgery you may want to look at the plugs if you have not recently done so already and let us know what you find. Hope this helps

First question, does it turn over, or does nothing happen when you thumb the button....

Try the obvious first...

Kill Switch - Nope not insulting you, just revealing how stupid I have been in the past

Sidestand cutout switch or clutch lever cutout switch - both these have been known to fail on Triumphs preventing the engine even turning over.... I'm sure I've seen some instructions on the ST forum for bypassing both these switches with wire to test them out.

Final one... Alarm.

Hope this helps

When it's pressed down it cranks but won't turnover. When I did have it running, it did backfire when throttling it hard but again it was cold and sat for awhile. I would say it's the carbs but this one is fuel injected. The plugs have been changed, that was actually the first thing I did. I have checked the kill switches on it (don't worry I don't take offense, we've all had those moments) Any other ideas?

Try spraying some Aerostart into the airbox when attempting to start it.

If it fires, it will rule out timing, spark etc. You'll have to look at whether fuel is being delivered.

Could be the injectors, a completely plugged fuel filter, water....

As the owner already recognizes, 98 t595's are FI, not carb[

How do you know spark & fuel are getting into the cylinders?

If it cranks, not clutch or sidestand switches. Kill would also be easily recognizable with no idiot lights on.

First off, as a new owner recognize that you should not use ANY throttle when attempting to start - if you have (& compounded by the ether into TBs) you have most likely flooded it.

Start by removing the plugs & check to see if they're wet - if they are, dry/replace them. If tehy aren;t you may not really be getting fuel into the cylinders. While plugs are out, check to see if you are getting spark at each coil.

One notorious issue on bikes of that vintage is the infamous ground block - that can give you all sorts of electrical issues including non-starting. DO a search on the site on that topic for lots of info regarding that.

JHans15, You should have three idiot lamps lit before thumbing the starter...green, neutral...red, oil pressure and yellow, low fuel.

You should also hear a relay clicking on right after switching the ignition on. Do you hear the fuel pump prime?

Alright folks, I shall try your recommendations and get back to you after my trials. Thanks again for the help and you'll hear from me soon.

are you sure your battery is in top condition, these bikes are really sensitive to that, you've done the kill switch checks on the bars and sidestand, there is nothing else I can say thats not been said but I dont think its plugs, or coils, it would fire on even one or two and for all three to fail at the same time is unlikely, and you say you have a spark anyhow, so that leaves fuel, or timing, as the timings done from an ecu thats unlikely too, as said can you hear the pump priming when you switch on? thing is if you have fuel spark and compression it should run, or at least try to, I would still try a new battery.

The battery brings up another issue. Replaced the battery recently, tried cranking off of that (not too long), let it sit for a couple hours, went back and the brand new battery was dead. This bike is becoming quite a headache but I am not about to give up.
