New SR but won't crank

[tsanumei4321]

NEW PROBLEM!!! No power
-I figured out that the wire from the solenoid to the signal switch plug was bad, i replaced it with one that was good.
-I then tried to start the car then I lost ALL power!
And after all this, no power. Any suggestions?

--info--
*Battery is at 12V
*Fuses at battery area and near clutch pedal were all tested and are good
-Battery ends tight and in contact

old info-I just swapped an SR into my S13
-My car was auto and looped the neutral switch, bottom switch, by saudering the two wires together, but did not connect any of the 3 switches near fuse box cause it's not necessary, such as the reverse switch
-ECU had a red light on it
-"Check Engine" light doesn't come on when put in on position
-Referred to "Frsports'" wiring procedures and did all exact.

+My battery is good
+ECU is for SR

Main Harness Plugs plugged in are
*ECU and dash connectors plugged in
*MAFS, TPS, CAS, IACV, 2-Chassis plugs, Knock sensor, Temp sensor, 2 grounds at intake mani.,
*Ignition Coil plugged in both sides
-Powersteering, oil press, and a few minor small plugs not plugged in.
-3 plugs at fuse box not plugged in, such as reverse switch..

Transmission Plugs plugged in are
*3 Alternator wires/plugs, 2 starter wires,
*A few connectors near fuse box
*Connectors to positive battery end

----So typically the questions I have are:
*Should i check ECU or any other plugs?
*What do I need to have power? Battery, fuses, plug-ins, etc..?

Any and all suggestions will be considered. I will start to make a list of your guys' suggestions and comments and will post them here with results. I will answer any questions also.

The one who gave the most useful info that at least cranks my car will be rewarded some dollahs

Mahalos, FOR YOUR TIME!!!

Is the strap from the solenoid to the starter case hooked up?

To aviod any headaches of a bad starter jump the power source to the signal. This will activate the starter to crank. If that works its in your wiring.

what i noticed is that anyone trying to swap a motor on the island of oahu has trouble because we are to low to sea level......

make sure that on your power cable the two white wires are plugged in. If they aren't firmly in then it won't send power to the rest of the car. Is your battery fuse showing 12+ volts?

Is your ecu grounded and all other grounds hooked up properly? And you had power once then tried to start and then nothing? If that is so you must of blew a fuse are you sure you checked all fuses under the hood?
