Have you checked for injector pulse? Might check the injection fuses.

lights dimming while cranking is not a concern do to the starter needing so many amps to turn the engine over, and as for not starting did you check the spark at the spark plugs? are you sure the injectors are supplying fuel to the cylinders? are you sure you got the timing set right? it sounds like a timing issue to me, or miswired spark plugs.

I haven't checked anything injector related because I know nothing about injection systems,but can't put it off I guess . Also I triple checked the timing,then engine is lined up vertical,and cylinder one is up while rotor is on spark plug one,and all the plugs are to the right plugs. It goes clockwise on mine, 1-4/2-5/3-6.

if your firing order is right and your got it timed wich you could not do without spark, it could be air or fuel, have you checked the air filter? if not that then I would tend to think its your injectors that need replaced but I am no expert at injection I know just enough to get in over my head. but thats seems like the next logical step to me
