2000 jeep wrangler just shut off changed fuel pump

If it won't crank, check clutch safety switch and cables for the starter.
If it cranks but won't start, you'll need to find out if it is ignition or fuel to know where to look next.

Check fuses first, but could be needs new CPU

could be the computer which is very hard to tell by a diagnostic machine

To me it sounds like you have weak battery. Hook up a meter and check voltage. should be over 12v, then turn key on. should maintain 12v. then crank. If the voltage goes below 11v cranking the battery is bad. Be sure to test the battery. Not the cables. Then tst the cables. You may have good voltage just touching the battery and you may have low voltage touching the terminals which would indicate a dirty connections.

The in tank fuel pumps on these vehicles have check valves to hold fuel pressure. possible bad fuel pump check valve, Try turning the key to the on position three or four times to let fuel pressure build up and then see if it starts easier

Check your relays. Find where you've got power and where it stops... you'll find the problem. Good Luck. "It's always something simple."

No, the ignition coil has nothing to do with fuel pump.

Your fuel pump is internally binding and causing the fuse to blow. Change the pump (and filter while you're back there.)

doesnt sound like the fuel pump!!
more like a bad body ground!!!!!!1

There is a fuel pump relay in the fuse box under the hood. See if it is clicking when you turn on the key. If not you may still have a blown fuse.
