I have a recurring problem with the fuel pump on my car, which can only be solved by disconnecting the battery for a few hours (thus re-setting the management system). The code I'm told, relates to a faulty fuel demand sensor which is embedded within the pump. If the engine is 'put under load', after a while the management system reverts to a different map and eventually after a few weeks, resorts to the 'get you home' map which causes the engine to run quite erraticly. I have been told that changing the pump is the only answer, and that the job is expensive to do.


I wonder if any other members have had a similar experience, and if the diagnosis is correct.

If you take the back off the pump ECU (on the pump itself) you may be able to solder the dry connections and get it working again.

Many thanks for the sugestion, I'll take a look and let you know if I'm successful!

dont solder the joints and if you do you will melt the whole thing then it will be f***ed

this is a common fault (dry solder joints), as the ecu for the fuel pump is bolted on the back of the engine, so gets very hot, causing the joints to dry out, so a common fix is to diy re-solder them, loads of people on here have done this fix themselves, for the cost of a solder iron and solder (£20 if they didnt already have a solder iron) as opposed to sending it of to a specialist who will only do the same thing £100+ or buying a new ECU £100+, and no-one has ever come back saying that there ecu is now knackered, in fact they sing there own praises on how there car drives like new again. As long as your not a complete numpty with a soldering iron, then this is a perfect, cheap fix.
