The other day I drove to the junk yard to get a part for another one of my vehicles. When I got back into my car and started it, it died after a few seconds, tried starting it a few more times and nothing. I had the guy come out and help me take a look at it. He put his ear up to the tank when I turned the key and did not hear the pump prime. He started banging on the tank and once he heard the pump prime he yelled for me to start the car, it fired right up and drove home without incident.

I was able to drive the car for the rest of the day without problems until night time when again, I went to start the car and it immediately died. I opened the door and got out and shook the whole car for about 5 seconds and got back in and started it and it fired right up. I drove it home and it has been parked since until today when I backed it into my driveway to begin looking at the issue. It fired up without incident today.

Does it sound like my fuel pump may be going out or could this be a loose connection somewhere? Any common problems with the cars and their fuel pumps? The car has 127,000 miles, I bought it with 111,000 and am not sure if previous owner had ever replaced the pump.

My vote is fuel pump.

 

The guy that banged on your tank must know Volvos. That trick will work a few times with a failing fuel pump- if there's a "bad" spot on the commutator of the pump motor, banging on it can get the motor to rotate just enough so that the brushes contact a good spot. But there's not much time left for that pump. Do the usual checks before changing anything, but you probably need a pump.

 

Thanks guys, I just changed it out. My buddy had a parts volvo in his yard, i took the pump out of there, swapped it in and just did an oil change then took the car out. She's running good!

 

Good to hear

 

Glad to hear it was only a fuel pump and nothing major!

 

Im glad it was only the pump as well. I was surprised how quick it was to replace, first one I've ever done.

 

Yes they are cake I have to do another on the wifes car tomorrow.(second one in a month)

 

Yikes. You may want to change the fuel filter.

 

Doing that as well here.

 

I think this car had a fuel pump done before. When I took the cover off, the wrapping around the harness' was already cut, the plastic itself on the pump wasn't very discolored. Should I look at doing the fuel filter as well? Just a though since you guys are mentioning it!

 

See, this is why I like working on European cars... the engineers usually take into consideration the fact that someone's eventually going to have to fix it, and they don't usually make it unnecessarily difficult to replace common parts.

I recently changed a fuel pump on my boss's pastor's Yukon XL. The tank was almost full, and yes, you have to drop the tank. A 30- gallon tank with no drain plug, that you have to remove from the vehicle to change the failure- prone GM fuel pump. Who thought that was a good idea?

 

Yes I would change the filter.

 

where was that thread on how to remove the fuel pump?

 

How the heck do you get that filter off!!?? It has some kind of slip fitting that I can't figure out.

 

I use a pair of needle nose pliers and slide it between the filter and the line and slide the line off the filter.

 

Ah, so brute force eh..? haha Just didn't want to break it.

 

The outside part of the line needs to be slid back some then the line will slide off.

 

??????

 

Not sure if there is a good how to thread on here. But it is pretty easy. There is an access panel under the carpet trunk mat. Remove the cover and you will see the pump. Remove the 2 lines by pulling up on the outer part of the line and slide the line off.
Then follow the wire up and unplug the pump assembly. Then get the ring holding the pump in loose and slide the pump out.
