Starting issues.. Not cps!
So this morning my car wont start the first time, it will start on the second or third try. I changed the cps last summer and it is not the same thing again. Seems like fuel pumps or fuel relay problems from what I've read on here. I checked under my seats like 4 months ago and there were no leaks from the pumps/filters but now since the starting issue I hear a buzzing noise comming from under the rear seat? Gonna check my pumps and relays right now. Any other thoughts? Thanks!

Checked the fuel socket on the right side, and everything was fine. When I removed the backseat and started the car, the pass side fuel pump was humming pretty loud. Never heard this before untill the problems started. So I need a new pass side pump? The part number I got from it is A211 470 1794, is this still correct or is there any updates on the part#? Anyone know how hard install is?

Did your pump running or making sound when you have the key in the "ON" position?

I can't remember to be honest with you... it literally happened like right when I got the car and I didn't know too much about all of these issues. I happened to do all the research about it after I got the problem fixed because from what it sounds like, it's likely to happen again.
