injectors
 
decided to check the injectors just to make sure there were no duffers got them all out,bridged the pump and there are 5 of them have an intermittent spray pattern and then when you press the flap down more they just stop is this the injs or the fuel dist or both im clueless :confused:

Swap the connections to a good and bad injector.

i gave that a go too but it seemed to be more or less the same,starts looking good then fires right out as it should then as i push down more it gets intermittent then stops altogether am i pushing too far maybe

Not driving it, check the flow pattern into a jar or whatever you did before, but with different injectors in a couple spots to see if its distributor or injector problems. Time and measure the flow at a fixed pressure might be good too, or just clean them all in an ultrasonic thing.
