Issue with 94 SI /GSR swap. Need help with Electrical
Well I thought i was wraping up my 94 SI with GSR swap today and went to fire it up. And it didn't turn over. All the lights on the dash kicked on 2 times when I cycled threw the ignition. On the third try all the dash went dark. All fans were still kicking on but no lights on the dash. Also the motor was not turning over and I did not hear the relay kick in at all at any point. I'm at a lost of what to do.
The back ground I can give you is. I did have one issue with the starter being HOT b/c some of the sheathing was removed and the hot cable to the starter was directly in contact with the housing of the starter. (before I tried starting car) It started an huge Arc from the postive cable to the battery, I saw this problem and was able to fix it. Not sure if that could have killed the starter? If it did why would the dash stop lighting up wouldn't it just affect the starter?
Everything is OBD1..... 94 eg SI and 95 GSR. I am using stock GSR ECU and OEM wire harnesses.
These are the only 2 wires I added to the ECU I'm guessing thats all I have to do for the KS and IAB? I did NOT switch any other pins or anything so I'm not sure if this is affecting anything?
The starter cable was in direct contact with starter housing and this is what caused the ARC with the battery. I'm not sure if this affected anything. This was BEFORE I had tried to start it. Like I mentioned all lights would kick on, on the dash the first 2 times but 3rd and 4th no lights but all fans were running. I Had battery tested and it checked out Good! As you can see I bent the cable away from starter housing wrapped the exposed copper with electrical tape and spaced it out with a washer to make sure it wouldn't touch.
Also notice the little plug that has broken lose from the previous owners JB weld job. It still makes good contact with plug.
As I'm at a loss right now scratching my head.

Sounds like you've got yourself an electrical headache..

Well "IG" is for ignition... you blew the ignition fuse because something was shorted to ground when it wasn't supposed to be. After replacing that fuse, did you check to make sure the starter housing is grounded to the chassis? It would need to be.

I'm going back over all my ground wires tomorrow. To see what I've missed... Have one off of the Valve cover, Lower transmission..... and thats the only ones I can think of at the moment.

The 3rd critical one is the engine harness grounded to the thermostat housing for the ECU. I assume that one's there already though if you're trying to start the car. If you don't hear your fuel pump prime then you shouldn't even get to the point of attempting ignition.
It's possible that you didn't miss something but instead something is in the wrong place. I would look for something that doesn't belong.

This is TOTALLY characteristic of a grounding issue.
Check your grounding strap from the trans to the chassis. I can almost say for 100% that this is your issue.
The car will ground out thru the gauge cluster or fan. It's happened to me before because I forgot to reinstall the stupid ground strap after a swap. I thought it was the most hilarious problem after the 1st swap. I thought I had F'ed up some wiring in the most bone headed way. Then I saw the grounding strap just flapping in the wind.
After I connected the strap, the car cranked and started right up.
This also happened with a loose grounding strap. I would imagine it could happen with a rusty or corroded strap as well.

Good theory. I forgot to mention that not only must this ground be present, but it must be THICK enough to handle the current. Think of the wire as a water pipe, and the electrical current as water (duh). Trying to run a lot of water through a small pipe will lead to a backup of water (current in this case). In essence, the starter is not seeing enough current to completely energize the primary solenoid because of the physical impedance. If you have doubts as to the thickness of your ground here, use two ground cables and see if that solves your problem.

Well, I got the car to turn over today, Fuel pump is pumping strong. Car would not start up tho. And none of the fuses blew, so I feel im getting closer. I'm going to go threw and check all the spark plugs to make sure each of them is giving out spark tomorrow when I have off (have to work now). Any thing else anyone can think of?

Thanks to everyone for their advice, the car is up and running! Something was screwed up with the distributer. So I ordered a new one and it all worked out fine. Only thing I noticed now is it seems to idle a little high around 1100-1200rpm's and was thinking it should be around 900rpm's. Only thing not hooked up at moment is knock sensor (waiting on tool to remove old one)
