fuel problems with walbro 255
ok i have a 98 ls1 with a vortech blower. i just installed a intank walbro255 fuel pump and it hardly runs, stalls out some, undriveable. but if i disconnect the maf it will run,drive down the road untill i go full throttle then the car boggs down and just will not go. i dont no if this is part of the problem but when i shut of the car my fuel pressure drops to 0.
the car ran fine before adding the new big fuel pump any help???

ok my car is not running its a 98 ls1 with 10# boost vortech and just installed a intank pump 255 lph. now the car will not run just spits and spudders. it will rev up ok in the drive way but will die out when i go to drive it just move it...and will not hold fuel pressure when car is shut off. when i turn the key on fuel pressure is at 20psi then start up 30 psi then rev up 31 psi thats getting in to boost any help?
