Need some help trouble shooting

[LargeTacticalDrift]

Ok, so I finally got my motor back and put it in the car, when everything was connected I turned it over and could here it wanting to fire off. It didn't because the fuel lines weren't connected but I just wanted to make sure that it was working. I closed up my shop for the weekend and when I came back next weekend and hooked up the fuel lines, I expected it to just turn over and start. And wouldn't you know it. Nothing. I know I have fuel, and air, but now no spark. Now before anybody starts bashing, i've used the search bar and studied everything there is on this. I'm just stumped though. There are 12 volts running to the coil on both the transistor and condensor and but it's not coming out of the coil. Everything is grounded and the cable from the coil to the distributor is good. Now i'm going to pick up a coil from the parts store tomorrow just to rule things out. But something else was bugging me. Since I came to a work stoppage with the motor, I decided to go ahead and hard wire the stereo and plug up everything. Of course the wires where fubared and cut and spliced to hell but I know what each one does and proceeded to finish the job. That's were the other problem comes in. The accessory power wire has 12 volts coming out of it but the constant power wire barely even moves the needle on my voltmeter. I've checked all the fuses and relays but can't find anything wrong. Ok. Now. Is it possible that there is something wrong in the harness that would limit power from coming out where it's suppossed to. I.E. the coil. And my constant wire? Any feedback would be great. I'm so close to being back on the road. It just sucks that I can't figure out what's wrong. I'm sure it's something simple.

Could you give a little more info on the year, motor, and mods?The only common things that would limit the amount of voltage running through the wire would be a burnt wire or a bad connection.Did you try cutting into the harness every 15" or so to see if there are any fried wires? Is the constant power for the radio?Did you check the large white wire under the engine fuse and relay box connected to the main fuse? (75A)I would check and re-check all your grounds. 99% of the time you'll find something on the re-check.Did you remove the ECU during your build?

The car is a 93 hatchback and the constant wire I was refering to is for the cd player. I've not checked the white wire you're talking about. I didn't even know about that until today. So thank you for that. I will try to check the constant wire again farther into the harness. If not I'll probably just run a wire directly from the battery and put a fuse on it. Thanks again for the help.
