check the fuel pressure make sure your new pump is working

I've check my fuel pressure and it pumping at an idle 50 lb when u barely ease on gas it pumps between 90 to 105

1,335

the 50 is good but 100 i think is over pressure. i think maybe you have a vacuum leak a hose unplugged or cracked do you have a codes from the computer ie check eng light

It shouldn't go higher than 65. Never heard of that happening but that IS a problem it it goes up to 100
