I've tried testing the ECM by disconnecting the ground and taking it the fuses. I've checked all other starter fuses and relays.

I've even hacked up the car to get under it and tap the starter with a hammer to knock anything loose. I've bought a new battery.

I've tried to jump it from another vehicle. I don't know what else to do. I need help, because this is my daily driver.

If it fixes the problem, I'm willing to take the ECM to dealerships around the area, but they say they can't reset the ECM without it in the car itself.

Long gone are the days of positive cables from starters to batteries, and negative to ground. Battery to starter, starter to flywheel, cranking amps to turn the engine...

I'm out of my depth here with all this electronic crap in cars these days. I just need answers so I can drive the car. Anything could be of help, thanks.
