Unhappy 1987 aw11 not starting

My mr2 started leaking from the distributor so I promptly rebuilt it using the kit from twosRus. Went to start the car and it would crank but not fire. Took the distributer off and realized I forgot the plug/cap thing. Put it on and went to start the car and it won't crank. Tried jumping it, new batteries, batterie charges. Figured it was my starter so I replaced it and the same thing happens. The solenoid kicks the gear out but it will not spin. Ive cleaned and checked the grounds and suspected fuses. Also replaced the alternator that blew sometime between all this. Out of curiosity, I tried to start the car with the radio on and it would dim severely and now the starter will not kick the gear out even while jumped and radio disconnected. I checked how much power the starter was getting and it's around 12v then drops to .5-1.5 while the key is turned. It has to be a power/ground leak somewhere right? I have also tried a new ECU and that did not work either. sorry if this is rambly.

It sound like you are not getting current to your starter.
I would look at the both the ground cable to the battery and power cable to your starter. Do you here a clicking when you try to start the engine? Davew

If you can see the voltage sag at the starter, you can find the fault just by tracing the voltage around the circuit with the starter energized. On one side of the bad connection will be battery voltage or ground, and on the other side will be crap. If the battery terminals sag, then it is the battery itself that is bad.

Thanks for the replies I'll try and trace the voltage. Worst case scenario I do have a spare wiring harness.

Just clean and tighten the bad connection. That is usually the best solution, unless a wire is really damaged. Keep in mind that with the kind of currents in a starter circuit, just clean-looking may not be good enough. You may need to scrape the mating surfaces bright before rejoining.

Did some more research and realized maybe the fact that I replaced the fusible link connected to the + battery is causing issues. I used a 12g wire. Supposed to be 16g.

12 gauge is larger than 16 gauge so that shouldn't be a problem.

It likely would be a problem. This is actually an inline fuse, not just a piece of wire. It is the last line of defense against burning your car up, so it is worth doing right.

However, the fusible link is not directly inline with the starter, so it probably is not the cause of this particular problem. The usual symptom of a bad fusible link is no power to any system.

Yeah my bad I should have been more clear..

Oversize wire there isn't the cause of the no start condition, but you do forego the safety offered by the fusible link.
