Question So... Fuel Pump It Is.

Well, after many pains in my ***, I finally find out that I need a new fuel pump. Took the damn thing in the other morning to get fixed. They call me back at around 4:30 telling me that it isn't my pump because my fuel pressure is fine, and that its my man sensor. I'm like fine, replace it. I pick it up at 6:30, ****ing thing isn't fixed! The ses light is off, but it's still sputtering and starting hard. Take it back in the next day, and wouldn't you know it my fuel pressure is low and my pump is bad. (but it wasn't throwing a code so they didn't bother checking it the last time even thought they told me they did. I guess they don't believe in test drives after repairs?). Mother ****ers.

Anyway, I told you all that to ask you this... Anyone have any clue what is involved in replacing the pump? I've heard you can do it through the back seats, but the guys at the garage (who quoted me some insane price by the way) said they had to drop the transmission in order to do it. I'd rather not pay a grand to have an $80 part replaced lol, especially after all the $$ I've had to dump into the ol' girl recently (hell, I even had to pay 150 bucks to for them to fix the wrong thing!).

Thanks for readin guys.

Re: So... Fuel Pump It Is.

You can do the fuel pump yourself in an hour or so. You can cut an access door above the tank and pull it out. Search around on here and you will get some good threads with ho to's. I highly doubt a shop would cut your floor up for you though. To do it the "proper" way, you have to drop the rear end/exhaust/gas tank and do it that way.

Re: So... Fuel Pump It Is.

Hahahahahaha.....drop the tranny huh?

Personally I don't like cutting an access panel in a unibody but it definitely is easier. I dropped the tank in mine and had my buddy inch his way up top to get to it since I'm 6' and 210lbs....it's definitely easier for a smaller person to get in there.

Here are some pictures for ya:

Oh and stay the hell away from that place.

Re: So... Fuel Pump It Is.

Most people cut through the ledge to get to the pump. If not, you need to drop the axle and exhaust in order to drop the tank, not fun at all. You cut a rectangular hole a little bigger than a license plate towards the middle and the pump assembly is right there. Do a search on how to guides as you should be able to find exact measurements of the hole and exactly where to cut. You need enough room to disconnect the fuel lines, otherwise, you'll have to cut the far one to have enough room to disconnect it (then obviously you would need to splice it back together). From there it's unbolting the assembly, disconnecting the wiring, and taking the pump out of the plastic canister and dropping the new one in and putting it back together. Be careful opening the canister as the plastic is brittle and you can break the hinges if you're not careful. Also, some people have made a locking trap door for easy access if you have to change the pump again.

I haven't done this myself, but helped/watched a friend do the swap, and if you're not careful, it'll take alot longer than 1 or 2 hours.

You don't need to drop the axle...the guide I posted suggests it which does make it easier but it isn't a necessity. I didn't even remove the tank, just had it lowered down at an angle and had my short buddy crawl around the top passenger side of the tank to get to everything.
