With the greatest of respect the first thing I'd do is strip the tank off put a new filter in, the tank will be full of shit(they all are) then put it back together as per the book check the pump and if it doesn't work ask questions.

I'm really the last person you should as I had 2 885i's from new and I thought they were both shite  :icon_lol:

So your saying the pump isn't working now?

And come to think of it Tim had the same problem after he had stripped his the pump had just got kaput but if yours is new it's either a connection or fuse or another pump to prove the other two wrong.

i ment the bike was running and ticking over ok untill i stripped it down and rebuilt it but now its as if there is too much pressure in the return hose from the common rail to the tank  and on the return there is only the port into the tank which is free and the fuel pressure regulator
thats why i think theres and issue with the fuel pressure regulator but id like to know exactly what it does

I can't help because I've never had a problem despite having my tank way into double figures but there's plenty of info if you google Triumph tiger fuel reg not anyone seems too concerned about such.

Starts, runs, then dies after a minute or so....

Dunno which options you've eliminated so basics.

Does it run ok with the fuel cap open?  Possible blocked breather.

When it dies are the plugs wet? Evidence that fuel is getting through (or not).

Are the injectors firing after it stops?  Take the airbox off and look in the inlets.

Reason I'm raising this is you say you have fuel pressure and a new pump, so... assuming there is enough pressure from the pump the only thing that can be happening is the relief valve isn't opening so there's too much pressure in the fuel line.  You'd know about it if that was the case because it'd have been a big spurt when you disconnected it and while it was running it would have smelled awfully rich.

Without checking the actual fuel line pressure it's hard to know what's going on.  If the new pump is ok and the pressure is down then you have either a leak, a blocked filter or a u/s regulator.  Checking the injectors are passing fuel will give you a clue.

If they aren't then the most likely reason is a weak battery.  (WEak batteries will crank the engine but the starter takes so much of the ampage that the ECU can't fire the injectors).

Hi thanks for the info it ended up being the plug inside the tank to the pump which was very loose.

But still not fixed
It ticks over till it warms up a little then slowly dies but if you give it a little throttle it runs but rough ?
