So last weekend i was driving my 00 ex on the highway and it shut off. put i back in gear and roll started it and it ran for a second until i took it out of gear, then it shut off. i parked it and tried to restart it and it wouldn't. I sat there for a while and listen for the fuel pump to prime and nothing. After a while i got it to restart for a second and then it cut off again. so i towed it and replaced the fuel pump. After the replacement it worked awesome for about three days and then today the same problem happened. I unscrewed the pump and tested the wires again and it wouldn't restart. I can't figure out what the problem is. i dont know why it keeps shutting off. I did read in the other threads about checking the fuses and i will tomorrow but if i replaced the pump and not the fuses last time that means that the fuses aren't the problem right?
Fuel Pump?

- Start date
swap out the main relay with a friend and see if the problem continues

If you lack both spark and fuel, the possibilities for the cause of the problem are more limited.
Does the CEL work?

More than likely, it didn't work. The problem was probably intermittent at that point, and you were fooled into thinking the problem was fixed. That's why troubleshooting rather than replacing parts somewhat at random is the best way to proceed.

its possible that the pump is not the thing that is failing

This does not tell you whether the CEL works. When you turn the key to ON(II), does the CEL turn on and then off after 2 seconds?

Check for spark at the plugs. If you have bright white spark, then use a test light to check hood fuse 44 and dash fuses 31 and 13. Fuse 44 should have voltage at all times, fuse 31 should have power with the key in ON(III), and fuse 13 should have power with the key in ON(II). Click the Test Fuses link in my signature.
If the fuses are fine, then check voltage and ground at the fuel pump:
If this fine, then check the main relay located to the right of the glove box.

Again, you don't want to guess what the problem is. You need to start gathering information about the problem. You don't need a mechanic to gather this information.
At this moment:
Does the starter crank the engine but it won't start?
Any CEL codes?
Does the fuel pump prime?
Is there spark at all four plugs?

Yes the starter cranks the engine but it wont start. No CEL codes. And the Fuel pump doesn't prime at all. It doesn't do anything when i turn the key to run. When i try to crank it it wan't to start but wont turn over. They replaced the dizzy because the plugs weren't getting any spark. but i dont think that has anything to do with the fuel pump to not prime.
