Not getting spark and other weird electrical issues.

So I finally got the engine in and attempted a start up tonight using a basic Crome basemap (stock ITR scaled for 310cc injectors) and ran into some very odd problems.
Scenario 1. Turn key to the on position, accessories light up and fuel pump primes but when I go to crank the car everything immediately dies as if I've blown a fuse. Turning the key back to the on position yields nothing. No door open chime, not ANYTHING. However, pulling the negative battery cable and resetting the ECU will often reset the problem giving me back my accessories until I attempt to start the car again.
Scenario 2. This time the car doesn't die when I attempt to crank it. The engine will turn over but it isn't making any spark. After a few cranking attempts it will usually revert back to the first scenario.
Scenario 3. Key in on position again with accessories working. Attempt to turn on headlights and the cars electrical system immediately dies like in scenario 1.
I've got the three main grounds connected securely and yes the valve cover ground is in the right spot. Someone mentioned to me it could be something with the electronic load detection circuit (ELQ it it's proper term I think)? Any ideas?

Possibly main relay. I've had to replace mine when I encountered similar problems as scenaro #1. Seems to be a somewhat common problem with Hondas.

I don't think it would be the main relay as the fuel pupmp is priming. When the main relay goes out, the fuel pump fails to prime. Plus the issues with the electrical issues being reset with the resetting of the ECU would lead me to consider other electrical gremlins beside the main relay.

I agree with this. Also are you sure the computer is ok?

Correct. I've just used the ECU recently to test out Crome on my hatchback so it should be fine.

It still might be - I had the same thing happen where the fuel pump was priming but the engine wouldn't turn. Broke out the multimeter and traced it back to the main relay. Unfortunately with an electrical issue like this you're best bet is to break out the manual and begin eliminating possibilities with the help of a multimeter. Good luck.

No but I'm using an Ostrich RTP chip emulator with Crome and this was the first time using it with the Type-R. Maybe it didn't send the data correctly. That's definitely something to look into.

That might be a good idea. I'm running 310cc injectors so it probably wouldn't crank but at least I know it wouldn't have anything to do with me altering the maps.
