406 Hdi Cutting Out When Towing Up Hill

[lawman67]

Hi To Everyone,

I have a V reg 1999 Peugeot Hdi Estate, I bought it for its towing capabilities after having many saloons.

I am having a problem when towing our caravan, When we start to go uphill (on any road) all of a sudden the car cuts out and stops dead. This when pulling a caravan can obviously lead to major problems on the road.

A friend with a basic "chip reader" has told me that the code showing is "fuel starvation to the pump" but past that he does not know.

The problem only occurs when there is a slow incline going up hill. I have to stop the car turn off the ignition and wind it over until it start again (for a few seconds the car seems to be without fuel) then it starts again and runs.

This only happens when we have our caravan on the back (never with the car by its self).

If there is a long hill, then it could cut out a few times before we get to the top of it.

The engine management light comes on and stays on until (it seems) the car engine cools down as when we come to it the next morning, the management light has turned its self off.

I am at a loss as to why this should happen.

Any help / suggestions would be greatly received,

Regards,

Tim

just a thought maybe u should get the high pressure fuel pump checked before u do anything else . Also is the engine smoking heavily when u are pulling the caravan

is there any written messages when the engine management light comes on?

also i have read somewhere that the diesels have a fuel filter that needs cleaning/replacing quite regulary by the sounds of it.

Hi,

There is no smoke either with or without the caravan, in fact its quite good at "not smoking".

The message is lack of fuel getting to the fuel pump, this seems to be correct because when I stop (and you have to) and crank the car over, it takes a few seconds for the fuel to get to the engine.

I have also replaced the fuel filter, but to no avail.

I have had the caravan on the car for a few test runs and it only stops when going uphill in a long incline - This is the bit that gets me ????.

Regards,

Tim

hmmm.....does it do the same without the caravan fitted, on the same hill?

just thinking if it does it under load or does it no matter what.

sounds like a fuel pump issue or a faulty fuel pressurer

many miles on the car?

kinda had the same prob with my 307 it was the intank pump was getting weak and could not keep the flow going when the car was up the rev range
put a new one in and the car was pulling 100% i would try that
