Car won't start; CEL/fuel pump do not turn on when key is turned to ON
I have a 1992 Honda Civic Hatchback CX. When I got the car, the transmission was bad but the car always started and the CEL would remain on when the key was turned to ON. The only weird thing was my aftermarket head unit wouldn't work. I swapped the tranny out with a working one and a new flywheel/clutch. Put it all back together and the car will no longer crank/start. When the key is turned to ON, the CEL does not appear at all, and the fuel pump does not kick on. When the ignition is turned to crank nothing happens; starter does not kick on. All engine bay grounds are checked and good. All fuses under hood are good. All fuses in the little box under steering wheel are good. I changed the Main Relay and still the same thing. The ignition does work because there is a nice and loud click from it every time. The starter works, we've tested it. The battery is 100% good. The starter also gets power from the battery. Car won't even pop start. What's the effffff is wrong? I'm thinking I shorted something out in the ECU at this point. Also, my radio doesn't work unless the constant 12v from the battery is connected to the 12v of the head unit AND the ignition wire from both harnesses. I dunno if that has anything to do with the problem. Please help me

Here's the G3 ground from the chassis to the transmission, all good, we used an even better ground than stock just for good measure

There may be two separate problems - ECU and voltage to starter.
With the key held in ON(III)/Start, does battery voltage reach the starter solenoid connector?

I'm just so confused because I put a new ECU in, the main relay is not getting anything because the new and old one do not click at all and the CEL never turns on. To check the starter solenoid do I put the multimeter to the positive and check the read out?

I had a friend turn the key and I held the positive to the starter power wire and the negative to the battery negative terminal and it read 1

Check fuses 24 and 31.

Lol, I've taken out every single fuse in both fuse boxes and examined them and they all look unburnt and clean, and I've even swapped them out with fuses equal to them and still nothing

So answer the question - where are fuses 24 and 31 located?

Alrighty...fuse 24 is located under the dash next to 25, fuse 31 is located under the hood all the way to the upper left corner

Click the Test Fuses link in my signature. Voltage test both fuses with a multimeter exactly as described at the link.
