My 306 XSI 2.0 16v keeps cutting out while I am driving..no pattern to it at all and it idles fine. I've had the fuel filter changed and diagnostics bring up no codes so my mechanic wants to change the fuel pump.
Does anyone know whether this is a good idea or have any other ideas becuase I love my car and don't want to sell it.
Thanks xxx

Thanks everyone for your ideas. Too many good suggestions for me to decide so I'm putting this to vote.
As for the car, I'm going to get the pump changed still but I'm going to ask about checking the pressure first and also about the other things mentioned on here.
Thanks again.
Vanessa

Mileage on car and what year? Trouble codes only show up if the problem is in the computer or sensors the computer reads or devices the computer controls. It still could be a problem with ignition items that are not connected to the computer or fuel pump or relay, bad connection, etc. which is why driveability issue's are sometimes maddening. You can throw parts at it till you're blue in the face and not solve the problem...if he suspects the pump is at fault, I would have him hook up a fuel pressure gauge to the system and then drive the car and read what the pressure is when this problem occurs...if the pressure drops and the stalling happens at the same time, it could be the pump or a bad relay or a bad connection/ground also. Maybe try the relay first...cheaper. Testing is usually cheaper than replacing stuff..hit or miss. Paul

Sure, it could be the fuel pump. However, it could also be any number of other things including bad plugs/plug wires, gummed up fuel injectors, etc....
The fuel pump it is a pretty expensive part and if the diags say the fuel pump is OK you should probably look for a more simple answer first.
Perhaps changing the fuel filter might be a better place to start?

Yes, as an experianced technician I have come across this problem before. The best option would be to change the fuel pump. But there may be a cheaper option which could be to change the fuel pump relay first. Hope this has helped and good luck...Ben

NONO! Stop immediately and go find another mechanic! Before replacing a fuel pump, the fuel pressure should be checked. That's a sure-fire way to tell if a fuel pump is going bad. If your fuel pressure is good and the pump is not whining then it's okay. Stalling could be all manner of things...don't let him go throwing parts into it and charging you for it!

It could be a clogged fuel line or a faulty fuel pump. If you can, try testing the fuel pump out of the car to see if it is really at fault, before having it replaced.

I used to be a driving instructor and on lessons my car would conk out or splutter for no reason. It took many mechanics and lots of garages and evaluations by professionals to find out that it was a thing called the butterfly valve in the fuel/ choke mechanism. Suggest it to your mechanic and see if it is maybe that which is sticking open and causing a fuel/ air mixture imbalance?

Yes it will.I expect it make a whining noise especially when your fuel tank is almost empty.If youre one of these people that runs your fuel down to almost empty the pump has to work twice as hard.Certainly sounds like a good remedy.

Absolutely. This is the main symptom of a bad fuel pump. Another symptom is that the car would not have as much power as you are used to. That would about clinch it. Trust your mechanic till he gives you reason not to.

fuel pump & filter. It could be multiple sensors. If it happens when the engine heats up and will re start when it cools down . You may want to look at the O2 sensor.

if the fuel pump is intermittantly cutting out then it will stall the engine, as the injecters are not getting the correct fuel delivery.
