Ok, heres my problem. I just finished my s14 sr swap into my s14 . Everything is ready to go. The thing is I'm not getting any fuel. I used a Walboro fuel pump, which i know works(i tested on a battery), but it isn't pumping any gas. When I turn the key to on, the pump comes on for about a second and then turns off. I removed the line from the fuel rail, and no fuel comes out when the pump is on. I even sucked(i wouldn't recomend this) on the line for about a minute until i was spitting out gas, so i know the lines arent clogged either. The thing is, thats its not pumping any gas(literally none at all). Its like it tries to but pusses out before it can. I don't know if there is something wrong in the wiring or what, but it seems like i'm not getting enough power to pump. any help is much appriciated.
thanks.

You switched the return w/ the feed line maybe?

Def check that first... then make sure that you are getting voltage at the pump... also you need to make sure you have a 15 amp fuse instead of a 10.. the stock on pulls about 9 amps of power, the walbro at max, can pull 14.6. so check the fuse also...

good luck

thanks,
unfortunately i've got the fuel line hooked up to the feed line and not the return so i know thats not the problem, also i do have a 15 fuse. I'm going to test the power going to the pump tonight, i just got a volt meter today. Is there any way there could be an ecu problem? I'm almost certain the pump isnt getting enought power. This is all very confusing and frustrating.
thanks again for the help
