You need to check the fuses and the fuel pump relay also check the wiring give these websites a try and if all fails stop by your local library and get your hands on a Haynes auto repair manual for your SUV wish you the best of luck Michigan Man.

So i change the fuel pump, not when i try to start it. it just turns over and wont fire. before it went down, it was shotting black smoke, running real shotty and would literally die upon starting or not...

first things first you should stop just throwing parts at a broken car its a waiste of your money...
first things first, check to make sure you have spark, then check the fuel pressure, can you hear the fuel pump working when you first turnthe key one with out starting the engine, also verify that you have power to the fuel pump. 90% of all fuel pumps replaced are missdiagnosis's. most of the time its the fuel pump relay. so check these things first before replacing anything else.

00 jeep grand cherokee fuel pump is not getting no fire. checked the fuse breakers even changed the computer. still no fire to the pump

When you state "checked the fuse breakers" did you check for power at the fuse block. Start checking power from the fuse box, then check for power at the end that plugs into your fuel pump. The switch will have to be on for the power to be present. My main concern is, if the fuel pump went out. But it's easier to check for the power first. If you're getting power from all sources, then the fuel pump has went out most likely.

No power to fuel pump car was running fine just quit repalced fuel pump no power to pump, car will start when spraying starting fluid in to intake, is there a fuse ? also replaced ECM, fuel filter,...

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.
