Replacing Fuel Pump

[mmclaren]

Does anyone know how big of a job this is?
After 2600km seems like fuel has stopped been pumped into car.
Unable to start. Electronics and sparks seem fine.

When fuel is pressurised after aprox 10 min. Car suddenly starts but stalls.
Thanks.

The job is not that bad. The gas tank is under the rear seat. Pull the bottom seat cushion out. The fuel pump is located behind the driver's side on LHD cars, and on the passenger's side on RHD cars. There is a DIY at www.pelicanparts.com.


Could you also have a clog in the fuel lines?

All i know is that i had just travelled 1200 k's Today and it just cut out, lost all power from the accelator.
When Listening it seems the fuel pump is no longer working.

When trying to start the ignition the car will not turn over, the spark plugs seem to be doing there job, seems there is no fuel Flowing through.

After leaving the car while and letter the injectors re-pressurise it will start to kick over but altimately stalls due to no fuel flow..

Any other opinions will be great

Thanks

The fuel pump in the tank is usually on the right side under the rear passenger seat. The seat is removed by just yanking up on the front and pulling out, no bolts involved. The fuel pump / sending unit assembly is about $150, the other side will have just a sending unit alone and it's about $40 to replace. You can spin the retaining ring off with a 1/4" socket extension and carefully tap it around to spin it free. Check that the fuel pump is in fact getting voltage with the key ON first.

test the voltage going to the motor first? that'd be a good place to start

theres no chance of water or any debris in the fuel is there? you could always remove the back seat and try to start the car while watching and listening to the fuel pump to see if it is doing anything. after all, it is right there in the car. or have someone else try starting it while to inspect the pump. hopefully, if it is clogged, then it is the pump and not the line somewhere inbetween!

fuel pumps are a peice of cake...easy to get to (pop up the rear seats) and easy to pull out and put in...
however the preparation and fuel safety precautions and doing it so your cabin will not be consumed by toxic odors for weeks is a real pain in the ass.

good luck.

Checked the voltage already forgot to mention that...
Voltage was fine..
Also i used an alternate method of listening for the fuel pump, its called screwdriver in the fuel tanker and using my ear with a friend trying to start it.. No sounds...
Well Drove 500k today with a new fuel pump to get my car fixed
and well...
Everything in that deparment is perfect, cruised home at 140k's an hour in 45' Celcius heat, no problems

nice.. replacing the fuel pump is good preventative maintence anyways. When i did mine it took 45 minutes and was simple. The old pump was filthy and I got better mileage afterwards.. do it if u got well over 100k mi..
