After take down and assembly 2013 TEX tries but won't start

I tried this as a reply to another starting issue: sorry, my bad.

Anyway, I tore down my 2013 Explorer and sidecar late last fall to paint. yesterday I got it all put back together, put fuel in it - turned over just fine, tried to start, but just won't catch. I removed the tank today to see if there was a visible problem with the pump assembly, found no problems. Put it back together, made sure the pump was priming the system at key turn on - it was, tried to start - no deal. Same thing. Turns over great and acts like it's going to run for a split second and that's it. I have tried turning the key on until the pump stops a number of times but it makes no difference.

I'm in a remote location far from any dealer - on Kodiak Island. Could sure use some help with this. I hate to put out almost $400 for a fuel pump if it's something else. Any possibility injectors could be clogged/dirty? The bike ran fine when I disassemble it. The fuel in it has been treated as was the fuel I put in it yesterday. Alaska does not put ethanol in our fuel. Is it even possible to clean these injectors in something like clean fuel or lacquer thinner or ???
Thanks in advance for any help!

The misery continues: Removed the injectors and cleaned them using the battery and jumper wires and some carb and choke cleaner to "pop" the injectors. They function perfectly. Replaced, put tank back on. Fuel, turn on the key, can hear the pump pressure up, hit the starter button, same ole thing. Tries to start but feels like it's not getting fuel. I could lay on the starter and spin till the battery died - so it's not the starter.
I would think if I had a bad coil only that cylinder would be dead.

Have you pulled plugs? Are they wet? Have you checked compression? Not something I recommend but maybe try a quick shot of starting fluid? That will help eliminate a lot of things if it fires on starting fluid.

Mouse nest packed in the air box?

No mouse nest, not even much dust. Fairly recent plug and air cleaner replacement.
Installed a new fuel pump. Still all it does is turn over real nice with an initial fire that makes you think for a second it's going to start.
Trying to find some starting fluid to see if it fires with that. Like you say - that will tell me if the injectors are firing. When I connected them to my battery with jumper wires they did function and they did let the cleaning fluid through. I made sure the short fuel line between the tank (pump) and injector rail was clear. Still, it acts like there is fire, but no fuel. I checked all the connectors and wires and fuses and found no problems - that I could detect.
That's where I'm at now - - -

It started and ran with starting fluid. Also seems to have run on its own by working the throttle maybe just using up the starting fluid.

Do you have anything to check and see if there's any stored codes? Other than having the bike in front of me, at this point I'm at a loss. I know with my Dealer Tool software I can go in and look at a bunch of sensor functions and run tests on certain things.

If you had the throttle bodies off, I'd check they're situated properly on the inlet manifold. I pulled mine back a couple of years back so I could get to the cam cover. Put them back on after the valve check, and it wouldn't run. Turned out they weren't quite on right on closer inspection. It's hard to see, and there's not a lot of room down there. Tough when there's only one Triumph dealer in the entire state, I know

Yeah I really don't know the extent of the teardown. Was it just things like the tank and fender for painting?

I just ordered a diagnostic tool (from the UK) so it will be as much as 10 days before it gets here.
I only removed the body plastics and tank. Since messing with this whole thing I have had the air box off and the fuel rail and injectors out to inspect and clean. I was able to look down into the valves and for having 32K miles on things looked pretty clean. Not much carbon build up. Maybe I'll try some fuel system cleaner just for the heck of it. I have not had the throttle bodies off. Took off the tank again today and once again removed the injector rail to be absolutely certain there were no kinked or clogged lines. I also went ahead the did the jumper wire thing on the injectors and ran some more Sea Foam through them. Got nice spray patterns again. I put it all back together again but did not put fuel in the tank. Tomorrow I'm going to go get some fresh fuel and see if that makes the difference. It really ran fine and sounded good while burning the starting fluid.
May just have to wait and see what I can discover once my diagnostic tool arrives. I would be a little shocked to find that all it was all this time was bad fuel. Usually our vehicles will start and run. They will run so - so or ragged but they will run. Perhaps the Triumph engine is more fuel particular =)
Thanks for the continuing feed back - been helpful and encouraging. Being out here on an island in a community only accessible by bush plane or boat is a helpless feeling when you run into problems like this. If it were an outboard boat motor I'd be in good shape.
