Yes. No crank sensor signal usually means no spark. The ecu has to receive crank position to set spark timing. I think you've really hit a big problem. You may need to get in touch with some people who have done this mod. I've always heard it's best and easiest to swap the engine with its ecu and the wiring harness into another car. Or something more compatible with that jdm engine.

Is there any reason that you have not checked the valve lash on the engine?It's really quite simple and if you have misadjusted intake valves the car will never start. Not to mention with while adjusting valves you will have to double check crank and cam timing twice (once at cylinder 1 adjust and once at cylinder 4 adjust)at the same time you will also be abble to watch dist.rotation and again be able to see that the dist rotor is in the correct firing position in junction with cam timing.ANYTIME a honda or acura has belt replaced you will check valve clearances,it changes with different belt tention on end of camshaft. when distributor was replaced was ignitor unit replaced,and coil (both inside dist. housing)replaced at this time?Hondas and Acuras both are notorious for failed ignitors and coils.(intermitantly even)this can result intermitant spark(either of the two) or weak spark when failing coil is problem. you may have spark but how hot is it?And last but not least ,most affordable but extremely coomon mistake...do not ever replace spark plugs on honda with anything but NGK spark plugs,if you use bosch ,bosch platinums you "WILL" see running problems and or no start!!!!!splitfire plugs will be destroyed within weeks in a Honda!And use nothing but a Honda Distributor Rotor. T.E.C is manufacturer of Honda cap & Rotors.You may be thinking to yourself how silly and anal i am about those things but i can say i have seen hundreds of civics,integras,preludes,with no starts,poor performance,etc,with customers"just replaced plugs,cap and rotor,they should be good they were expensive bill at checker said they were the best".hundreds of dollars later and driving out with NGK plugs and honda cap and rotor,lesson learned
Mine was running fine driving 70MPH on the highway and just shut off. Now it cranks, fuel pump runs and it seems to be getting fuel but still no spark. I have a coil/module on order and will try it tomorrow.
UPDATE
Replaced the coil. Coil sparks once when you first turn the key on, that's it. crank sensor has already been replaced yesterday.
Injectors seem to fire (I smell fuel if I crank it a while) but still no spark.
I have 12V to the coil and 12V when cranking.
I see tons of posts with this issue but no resolutions. Come on somebody has to have been here before....
UPDATE #2
I do NOT have an injector pulse or a pulsed signal to the coil. When I crank the car the oil pressure light blinks on and off (just noticed this not sure if it is relevant)
I do get a check engine light when I turn the key on and when cranking, thought this meant ECU was good?
Any other way to test the ECU?
Could the pick up in the distributor be bad? Doesn't the pick up signal the ECU to fire the coil and injectors, I thought the crank sensor was just a TDC reference point?
