ive been on the forum for sometime now and i havent really posted in almost a year so hi yall ok so heres the deal the fuel pump has went out on my car 2x and i think this is going to be the third time here are the problems rough idle when starting and when i was last driving the car the it seemed to lose power so i think its the fuel pump again but the battier died after two days of sitting and now i think the alternator is gone as well since after i jump the car it wont fire up again until its jumped so does anyone have any advice to give the last two pumps that were installed were ( im guessing) Nissan parts im now going to get a washborune 255 on ebAY since all the junk yards around this corn field dont have 300zx's oh another thing is that i tried to get to the fuel pump from the trunk of the car but two hoses were in the way how do i get them off without taking off the tank and do yall recommend anything else
