Still not getting spark and I don't know what else to do.....

I still can't get the Type-R to get spark and after this past weekend I'm really lost.
Basic rundown:
Installed a brand new bottom end and transmission but can't get the car to fire. It has a ODB2-1 conversion harness and has been wired with resistors for aftermarket injectors (originally DSM 450's but now Precision). Other than that the wiring harness has not been modified in any way.
The car has a brand new distributor. I've checked all grounds on multiple occasions and PGMFI fuse under the hood has continuity. Fuel pump is priming when we turn the key to the ON position.
This weekend we tried a host of ECU's with some interesting results. We tried TWO modified chipped P28 ECU's, one of which the car had been running on before I pulled the motor, the other from a friends car that is known to work correctly. BOTH chipped ECU's threw a constant CEL and when we jumped the service connector it would NOT give us the code. Now there are a couple of plugs that aren't connected at the moment (crankshaft speed, powersteering and possibly the IACV) but none of them, from my reading at least, should prevent the car from firing and definitely not throw a constant and uncheckable CEL.
After that I pulled the stock and unmodified ECU from my 2nd gen GSR just to see if the car would get spark from it (we knew the car wouldn't run with but it should still give it spark). With this ECU the car DID NOT throw a CEL at all but it still won't get spark.
So if it's not the ECU, not the distributor and not the PGMFI fuse what other things will keep the motor from getting spark? I'm really starting to lose hope that I'll be able to figure this out on my own.

With the injectors are they low impedence or peak and hold? What resistor box did you use? Are you sure it is wired correctly?
New bottom end...is it all OEM? What about the head? Is that all OEM too?

Resistors are wired in correctly. The car had been running with the DSM injectors for several thousand miles before I pulled the motor. The only thing I can think is if the new injectors I got weren't the correct ones but would that cause the car not to get spark?
The bottom end was bought brand spanking new from Honda. Head was redone by Alaniz technologies so I trust it's in good order.

I would think that from my own experiences, the injectors would either be flooding the engine or not supplying enough. I guess you need to check what type injectors you just put in.

But that still wouldn't keep the car from getting spark would it?

This may sound silly, but are your plugs gapped properly? Are you sure you got the proper distributor? Are you sure that the plug wires are in the correct order on the distributor and terminated onto the spark plugs correctly? Is the wiring harness plugged into the distributor properly?
pull the plug wires and ground them one at a time to the valve cover nuts as you're trying to crank.
if the injectors are firing, you'll get gas in the cylinders... and if the plug wires are firing (in the correct order?) then you can go to the plugs. my guess is wrong firing order - maybe you switched the plug wire order up? Or possibly it's ecu related (which is always a pain in the ***). Double check all your plugs and plug them in. crank angle sensor, etc!
