Hello all I have been lurking here for a few months alot of great info here, My mom has a 1993 240 and the place she took it too wants $600.00 to change her fuel pump!
Can some please let me know where it is located and whats involved in changing it.
I am pretty mechanically inclined as far as motorcycles go so I am pretty confident I can change it I just need to know where its at and if there any procedures I should follow. I just cant see her paying that much just to swap out her fuel pump
Oh and its a wagon if that helps

Any help would be appreciated,

Dean

The fuel pump is in the gas tank. It is an absolute pain in the ass to fix. Trust me, I've done it.

The only piece of advice that I can give you is to check the fuel pump relay first. A common mistake that a lot of mechanics make is that they only test the pump and not the relay. I went from having one mechanic telling me that it would cost me $800 for a fuel pump to having another tell me that I just needed to replace a relay for $40. Even with labour, the relay is considerably cheaper to fix.

Hope that this helps.

Your car has 2 pumps. The one in the tank is a pre-pump. If this is bad, the car will still run if the fuel level is high enough. the other pump(main) is located under the drivers side rear seat floorboard. And yes check the fuel pump relay. You can remove the plastic cover and check for bad solder.

Hey, hope you don't mind if I jump in with a question. I've had both pumps and filter(s) replaced, as well as the mass air meter, injectors and distributor...ICK! FINALLY I found out about the relay by ditching the mechanic and looking it up myself. SO I was happy to hear that the symptoms of a bad one matched mine...super rough start and very annoying intermittent stalls(heat related). So tonight, in the dark(just got the relay) I was very excited to try and "plug" the new one in. When I got under the plastic shield I noticed that the metal lines to the left are COVERED with melted black gooey stuff. Being that I have no idea what those lines are..I ignored and tried to switch out the relay. Did my best, and now the car will not start at all. And I don't hear the pre-pump priming at all. So, I plan oon putting the old one back on in the AM to see if my after market box is faulty. BUT...I broke the little spot(on the back of the old relay) trying to get the metal latch thingy off. Am I ruined? I'm so tired of paying a mech to look into this. I want to fix it my self! (with all of your help, of course) advice?? MUCH APPRECIATED! <3
