Alfa 156 2.0 JTS fuel pump

Hi All

My 156 broke down this weekend, luckily right in front of a garage.
Engine cut out and would not start (turnover ok but no fire).
The mechanics did some roadside checks but decided to take it in for further checks on their diagnostic system. They phoned me up and told me it was a problem with the fuel pump.
They rung up the Alfa dealer and were quoted 850 for a replacement!! they then decided to call me again and suggested that I get a second opinion before proceeding with a costly replacement only to find that it wasnt the pump after all.

So my query is this. Is this a normal price for a pump?
Can i fit a second hand pump.
Can anyone tell me excactly what pump I need.

Alfa 156 (2005) 2.0 Jts Veloce.

Getting a second opinion from the alfa garage is going to cost an arm and a leg anyway, so my thought are to find a second hand pump first, just to see if this is the problem.

Any thoughts greatly appreciated.

Does he mean the electric feed pump in the tank, or the mechanical high pressure pump on the engine?

There is a fuel filter under the car near the tank to check too.

Mechanical high pressure pumps don't give problems very often and they are the dear ones.
Electric ones in the tank do fail sometimes but they are easy to check,just disconnect the pipe in the engine bay ,get somebody to switch the ignition,on the MAR(just on)position and if the pump is working you should get a burst of petrol (make sure you have the pipe placed in a little container).
If there is no petrol,it could also be just a faulty relay not switching the pump on.

Good question .. well presented.
I have a faint recollection of the words 'high pressure'. I will have to confirm this with him tomorrow.
Thanks for the fuel filter tip also.

I am gathering as much info on the problem as I can. I'm not a mechanic by any strech and feeling a little Vulnerable at the moment with my car 80 miles away at a garage with people i've never met before.

Many thanks 'Alfa tuner' and 'David C' for your advice there.
I also remember he said it was a Bosch unit.

Have you tried to start the car again? If it runs then its most likley the crank sensor thats the problem. When mine died recently both the recovery drivers told me it was almost certainly the fuel pump (thats after they told me it was the cam belt).

Why dont you just reach under the front of pasengers seat and podge the crash button?

If it is the HP pump (located on the gearbox end of the exhaust camshft for all those wondering) then ask them if it is just the spacer pin that has snapped off, as this pin is part # 60676425, costs 12 and takes 20 minutes to replace, I've seen this happen on a few JTS' now and it is there as a sacraficial break in case of cambelt failure or pump jams. Often though the pump will just get a spec of dirt in, jam and shear this pin, just back flush the pump and replace the pin.

The high pressure pumps don't often give bother - so do make sure the problem is properly diagnosed before replacing it. That being said, I do have a used one on the shelf if you need one - 01525 221 921
