refreshed motor install, won't turn over

[Driftin]

So I have an 88 IX, and I swapped in a healthy motor from another IX and did new waterpump, timing belt, pulley, blah blah blah, and it won't turn over. No solenoid click, nada. Dash lights light up, but nothing is getting to the starter, or the fuel pump, (so likely not getting to the ignition relay either). I did have a solid short occur between the positive that goes to the starter and the body the first time I reconnected the negative terminal. (cool sparks!) Is there something in line that I blew? I checked all my fuses, and am using relays from when the car was running.
I am more familiar with Toyota cars, does the e30 have a fusible links type connection that dies as a protective measure?
Do I have to enter some weird code in the computer? (just shooting in the dark here)
Not sure if this matters, but I still have to put the steering column stuff back together on the interior side (switches, plastic cover for column, etc.)
Anyway, I would be grateful for any ideas to get me started....

Check your main engine ground. It's located on the left front, bolted from the oil pan to the body. You'll have to pull your air box to access it.

Basically, any time you are having multiple electrical issues, grounds are generally good to check. Since you had the front end apart, maybe you forgot to bolt it back up.

It just so happens that the E30 has a single main ground, if it is worn out or not connected, your car won't do anything. Get it cranking first, then check out the fuel pump issue if it persists.

Main ground is good. Cable is in good condition and bolted to the correct spot.

What is the battery voltage? The battery may be discharged too much to operate the starter.

[Driftin]

Could be drained battery, I left it charging overnight, we will see what it does when I get home.
So I shouldn't worry too much about the effects of a significant short? (dunce cap on in the corner)

had the same problem during my install...the main wire from the fuse box turned out to be hooked up wrong, but figuring this out fried my alternator first

You guys are so smart. Hooked up the 4Runner for a jump, and it turned over once I unplugged the battery. (must be dead). Next step check for spark and fuel... So smaht...
