Default STILL NOT FIXED! XR31 EFI Not Running

Thing is I don't know what tells them to do so, I should imagine that is what the speed sensor is for?

Okay - an update -
After weeks of scratching my head and thinking logically (or so I thought) I took the injector rail off, injectors out cleaned them out properly by rigging up a plunger with carb cleaner hooked up to a live feed. Replaced everything, cleaned everything and.....NOTHING - Still won't start. I then sprayed some fuel down the throttle body and away she went and run for as long as the fuel down the chamber lasted.

Back to square one - does anyone think that maybe a weak fuel pump could be to blame?? I only ask because I seem to remember it spluttered momentarily once on the motorway at about 70mph and at the time I put it down to shit in the fuel. It has an 'intank' pump!! Does anyone know where these can be bought new or can you wire up an out of tank one up in tandem??

Any help would be appreciated!!
