Not getting power to half my fuse panel even with key on

All power is working with key off and on. ECM connector was loss. But that wasn't the original problem. Still Electrical.
Car ran fine till ran out of gas one day, towed it home got gas then ignition went out, does not do anything when turning key not even click, so put in a 2 pin push button switch, 1 wire to starter solenoid and 1 to battery +with fusible link. Don't know why wont start. Getting spark fuel pump pressure good. Check engine light is on, was reading I think a 21 or 22 get sensor, replaced that, now check engine light is still on but bong read no codes, doing this with paper clip. Never checked a fuel injector before but no I should check for pulse, but can't get to them without taking the top manifold piece off.

60 psi after fuel filter under car and 42 at Shrader valve. And can hear fuel pump prime when turn key to on not start.

Spray staring fluid where air filter is in box?

Yes it does. This means it's the fuel pump? Right? Please let me no ASAP so I can go buy a new one and pull the tank so I can get my six brats to school and get us some food. Thank you

She only has a hundred and nine original miles and I'm the second owner. I'm just going to put a new fuel pump in it plan on keeping it for a while. I have already unhooked the whole gas tank hoses and the two brackets, have a transmission jack underneath tank itself has a shield around the exhaust side won't come down. Is there a certain way to shimmy it out? Is it supposed to fall straight down? I even took all the gas out of it the shield.

I thought so. Towards passenger rear door. Will let you know if it starts after installing it. Hopefully tomorrow

Not if, when I get this car running good, is there anyway to sup up engine, this little car can gets. Of course inexpensively. Came with an after-market cold air intake but when I first got the car I tried putting on and the car wouldn't run sensor that's in the air filter box so just put back on Factory box because car wouldn't start. But started as soon as I put back on Factory box and thank you for helping. Hopefully this works.

All put in, but still don't start?

Figured if I can hear the pump it getting power, now I can really hear it. Connector to fuel pump is easy to reach under trunk. It has three wire, purple, light blue and a black or big green.
How would I test with multi-meter?

Yes getting power on fuel pump. When I spay starting fluid in air box it wants to start, but doesn't. Just replaced spark plugs too.

Is there any way to test computer, to verify it's the computer and not the wiring going into it?
