The injector pump on my 2003 307 2.0 hdi 110 has gone faulty loses pressure overnight and needs to be replaced. Although the car is 13 years old it runs like a dream a new pump from my local Peugeot dealer has been quoted at £569.00 just to purchase fitting cost around £250.00 I have found a salvage agent who has several injector pumps that will fit the car but needs the part number to determine the correct one. My local Peugeot dealer where I have spent many hundreds of pounds with over the 10 years that I have owned the car wont give me the part number but will sell me the pump. Can anybody please help me find how to get the correct part number.

Many Thanks

1, if your car is running fine why do you need to change the pump?

2, how do you know the pump is faulty, a pump does not store pressure overnight.

3. are you having any starting or running problems?

I have had the car checked by a French car specialist who ran a pressure test and other diag test they found that if the car was left overnight the fuel pressure from the injector pump was low once it reached the correct pressure the engine would start and would continue to start all day. There is also diesel weeping from the housing at the top of the pump and they think this is where the problem is.

it could be the starter motor not turning fast enough and is a problem well covered on this forum also a failing battery and bad connections can do the same

307 2.0 hdi 110

I had a new battery fitted along with new clutch and flywheel 4 weeks ago. At a cost of £1.000 plus I cannot afford to keep throwing money at it would I need a part number to purchase a new starter motor.

just because a battery is new does not mean it is not faulty get it tested also check the battery connections and engine earth connection by taking them off and cleaning them, the alternator could also be not charging correctly and this can cause the battery to fail

you could check and clean starter connections too

finding the fault is what you do to stop spending money on parts not needed to fix the fault, if you changed the pump and it was just the same then that would be a waste of money

Thanks for your advice I will get onto checking and cleaning connections and see how I go from there.

Leaky pumps usually still start fine and once running the leak stops but if you really want to change the pump a used one would be fine as to be honest its not a common issue i have stopped listing them as they rarely do sell.

Renault pumps on the other hand they fly out the door :)

Leaking pump heads can cause poor starting (they stop leaking once there is a bit of heat in the pump body).

There was a recent thread on here on fixing with a repair kit (I did my 307 about 3 Yrs ago and it was fine over 100K later when i sold it).

Its not to bad a job and parts cost no more than £30

All the comments you have made have led me to believe youre getting a bit mugged off here.

£1k for a clutch and battery? Thats about twice the price you should have paid.

As for the pump pressure, the pump will pressurise when you turn the ignition on. It doesnt hold pressure overnight and therefore doesnt lose it.

If you re having starting problems first thing on a morning I would suggest its either your fuel temp sensor or the starter.

Dont go spending loads of money on it without posting here buddy.
