13B REW into a 73
swap is complete...but car wont get spark. plus the battery gets drained in like 2 days. Wiring? Any help would be wonderful. I spent about 4 hours just searching this site on hits for spark, 13B REW...and I found some helpful threads...and PMd a few people 
but still nothing. If anyone knows anything at all on what else I can do...it would be greatly appreciated 
Alexis
thanks again! Alexis

the engine is cranking over fine....the start signal to the starter is hooked up right..thru the rx3 ignition switch also wire is going to the ecu telling the ecu that the engine is trying to start..when the ignition switch is in the start position
also 12v while the ignition is in the on position and start positon going to a 30A ignition relay which powers the switch wire on ecu. also i have a 12v constant fuse wire supplying the constant wire on ecu all sensors on engine when key is in are all getting correct voltages...example tps 5v and so on
also i have 4 wires going to the coils one is the supply coil power and the other 3 i thought were grounds that ecu triggers i checked voltage at CAS and thats correct...from what i understood the CAS tells the ecu to tell the ignitor to fire the coils ?
ive installed new ground cables from chasis to engine with no success on getting spark
the 4 wires going to the coils...one being 12v for coils the other 3 are supposed to be grounded by the ignitor have 12v power when key is on and while cranking. is this the problem?
Help?
Alexis thanks

There are seven wires on the ignitor out of 8 pins (one isn't used)
3 go to the ecu (they are T1 T2 and L trigger wires)
1 is 12V+ via a switched fused source, this same wire goes to the + on each coil and the condenser, the condenser is a small capacitor that goes to ground and acts as a filter.
3 wires go to the neg of each coil, this is the only thing that connects the coils to ground, if one of these wires is grounding I think it will ruin that channel of the ignitor.
You can test the ecu's signal with a multimeter with continuity beep.
I gave several wiring diagrams to the person I believe was probably setting up your car. I set up a 13b-rew off the stock rew ecu in my FC. Its too bad he couldn 't get it going. I think his name was Rich.
I would use the FSM to verify that the igniter is good first, then check that the ecu is infact turning on, check codes on the ecu and verify that the ecu is seeing the CAS.
This is most likley a wiring problem, but could also be a bad ignition pickup, ecu, ignitor.
Check the wires running into the mag pickups, they often break right at the connector.

Its far easier doing this sort of work with a proper standalone. I know of a few mechanics that will install and put a basic streetable tune on a haltech for 4-500 bucks.
The FD's engine controll system is an over complicated cluster ****. Now that my swap is smog legal I have switched to a haltech e8.
I would be happy to talk to Rich over the phone, I think I gave him my number, before, he certainly has my email address.
