Local guy is an idiot, how is it intermittant if it wont start. If there is injector pulse, then it wont be cas, does the fuel pump come on with ignition for a few seconds, and then again when cranking? Power at the coils, Ecu and igniter/coils earthed? Are you sure there is no spark? You can measure Afm voltage with ignition on at the ecu to confirm wiring and afm's. How do the plugs look? Maybe Double check the cam timing, and while you are at it does it still have the locating pin in teh front of the exhaust cam to align the cas?
