Cabby cranking but wont start

My cabby will no longer start.
I have good fuel pressure, Got sparks, compression test ok. I can even here the injectors ringing.
Any ideas.
 

Have you sprayed any easy start or carb cleaner in TB

Have you checked the valve timing to make sure it hasn't jumped the belt? Have you cracked the union on top of the injector to confirm fuel, be careful about how much fuel you pump into the bores as this will dilute your oil viscosity, can cause premature wear to the bores and rings. A change of oil would be a good idea if you can smell fuel from the oil on the dipstick. Have you tried changing the spark plugs, although they can show a spark out of the cylinder they can degrade under compression pressure and/or too much fuel
Is the battery properly charged and spinning the engine fast enough, try giving it a boost with some jumper cables if everything else is good.

“Sniff” is really the last resort and not particularly good for your engine

So many possible checks, from previous issues I can suggest:
Maybe Worth checking/swapping out the coil.? I had a similar issue when it was cold/damp and it solved it instantly. 
Have also had the belt jump so worth checking timing. 

Thanks. Its Cis injection engine. Changed oil last week.
I lined up Tdc from mark on timing  wheel to head at rocker cover. Then set dizzy rotor to mark on edge. Checked firing order all good.  Not sure how to check timing. I removed plug one and put in scew driver and Tdc mark  is accurate. What else can I do to check or set timing.

Has the non starting occured since you made the adjustments?

when you took the plug out was it
wet ?

take the 5th injector out see if you have fuel
it will start on the 5th injector you say you
have a good spark if you have fuel even if
the timing was 180 out it would backfire
fancy no fuel myself
