can anyone help me out.

this is the story

bought a 954 it ran for a couple days and all the sudden fuel pump died. so i changed the pump and got it from an aftermarket company. the pump started at first when i jumped it off the battery and then installed it. ran for a lil (15 min on a test ride) and then when i turned the bike off it wouldnt start up. took pump off... no power.

could it still be the ignition if it started it off the new pump?

when i say i, i mean the mechanic at a shop in phx. they are newer. but they say they checked all fuses and relays ect. there is gas in it. i have been reading about this a lot but i have not found an answer to the above question. sorry if this is a repost. please help! i have a lot of parts on the way from an online shopping spree!
thanks

Is it a high-pressure pump?
You need to make at least 50psi, which most aftermarket pumps won't do.
Car injection systems generally run lower than this.

The specification sheet for the pump will say what pressure it's rated for.

would it not get power if the psi was off by a lil?

Not if you tested it before putting it on the bike.
Since the bike is designed to power a high-pressure pump perhaps it damaged it when you ran it?

Check to see if you have power to the pump in the first place (now) and recheck your fuses if you do not. If you do have power to the pump then the problem lies (most likely) in the ground or pump.. easiest to check the pump ground with a voltmeter/continuity checker. Try that out first.

i have a lot of money in **** that i bought for the bike to upgrade it. from levers to exhaust and mirrors to gear. so u can imagine my frustration. so to those that have helped thank u and if u can help me further that would rock. i am deep in labor to where the bike is not worth what i paid anymore so if anyone is in arizona and can help me out that would be even better.
