Jackal won't start after sitting a year+

[Cadyfatcat]

My 2000 Jackal has been sitting in my parents garage for over a year now, I was living elsewhere and had no space for it. Anyway, trying to resuscitate it now and not having any luck. I put new gas in it, got nothing. If I shoot starter fluid into the cylinders it will start and rev for a second before it dies, but won't idle for any period of time. So seems like a fuel delivery issue.

So if the bike had carbs I would think the carbs were gunked up, but with the fuel injection I have little experience. Where do I go from here, is there a way/does it make sense to clean out the injectors? Perhaps the fuel filter is gunked up?

Thanks

     Fuel pump not running?

[Cadyfatcat]

I did not think the issue was the fuel pump, because 1) when the bike starts on the ether I can rev it for a second before it stalls out. 2) when I flick the on switch I still hear what i believed was the fuel pump priming the cylinders (maybe im wrong, sounds like a little electrical actuation noise.)

Could be wrong about this stuff though

 The fuel pump will make a very noticeable sound and will run for a couple of seconds . If it sounds like it is straining , it may be plugged up . The engine will rev for a moment even on starter fluid , and I might advise against using much of the stuff .

I had the same problem with the same symptoms.  I noticed there was no clicky noise or feel to the injectors, which suggested that either the solenoids weren't firing or they were gummed up. 

Although I removed and cleaned the injectors to solve mine, you can maybe get there with a smart rap on the injectors as you toggle the kill button.  Once they start firing some injector cleaner in the fuel will help clear out the rest of the gum.

Electric fuel petcock working?  Or, manual fuel petcock open?

Confirm you are getting fuel by removing the return line at the front of the tank and directing it into a bottle,
There are two hoses at the front, the one with a fitting is the return line.

Ok good information here, will try this stuff and report back

I am guessing if I am getting fuel to the return line in front of the tank it still could be a clogged injector issue? but if no fuel the clog is likely at the filter or before

About access to the injectors, is it pretty easy to access them if I pull off the tank?

put some seafoam in the gas..
does it crank over well? these fi bikes don't run if your battery is not fully charged.
the petcock has a screen inside the tank, if it's clogged from gunk or rust in the bottom of tank fuel flow can be restricted.

Here's a much more severe case and the product he used to fix it.

Yes, the fuel should come back filling the return line, If the bike has been sitting with water in the tank it will rust, the rust blocks off the filter because it can't get back out and all you get is a dribble coming back. The filter doesn't need replacing just a backflush.
The petcock strainer could be blocked as well remove the hose from petcock to pump and make sure you get a good flow with the petcock open.

If it's blocked in either place the pump will be extra loud, more of s groaning noise.

While you are at it remove the tank filler cap and dribble a few drops of light oil into the moat drain, it should disappear indicating the drain is open.

Which ECU does the bike have, the small one or the old P8? either way this is a good description of how the ECU works.

Ok so I removed the tank and used a funnel, fuel is flowing quite quickly through to the return line. So no issue getting out of the tank or past the filter. I am assuming the clog must be further down toward the injectors or the injectors themselves. Injectors seem like they might be a pain to remove though, anybody know an online tutorial for that process?

[rodekyll]

Removal is simply (HA!) removing the screws holding them in place and popping them out of their wells.  Doing that will tell you if they spray or not, but you already know they don't.  Have you done anything I suggested earlier?

I think it is a torx bit, you get to it from opposite side w/ long 1/4" extension. This is from memory been 4yrs.
