4x4 saph cosworth running prob
been too work on a car for a mate of mine , and cant figure why the car when running is not burning the fuel in bore 2 +3 even though there is a good spark on all 4
the lad has changed 4 plugs, new rotar arm , dizzy cap , phase sensor ,crank position sensor , new water temp sensor
strange one for me , compression is fine on all 4 aswell
any help much appreciated

Have you changed the leads? I'd swap them around, put the good leads onto the bad cylinders and vice versa, if that changes things then the leads are duff.
Also if this doesn't work you can check the injectors are getting signal pulse controlled by the ecu, but unlikely to be an issue if some fuel is getting through and 2 of them are definately working, would more than likely effect them all.

Sounds as it's overfueling as with most his gone in head first replacing all sensors to no avail, check the MAP sensor hose is in good condition and not cracked and that the phase sensor wires have not corroded and shorted, also check the injectors are pulsing correctly. The most unlikely thing is that the earths for the injectors have shorted but think you would notice this as injectors would run all the time.
