106 Fuel Pump Problem
Hi All,
I'm having a problem with my '95 106 1.0XN, Single Point Injection.
Basically, the fuel pump keeps cutting out. I've got the covers up, and tried a multimeter on the pump connector, and it would appear that it is the electrical supply to the pump.
Does anyone know what relay (if any) controls the pump circuit, or where it plugs in?
Any other diagnostic/fix recommendations VERY very welcome!!
Thankyou!

Hi Pugxpert...thanks for your help, you're the first person to be able to tell me where the relay is!!pugxpert wrote:brown double relay under engine ecu will control fuel pump,when your car cuts out have a bulb connected to supply and earth on pump connector if bulb stays lit when it dies pump is at fault,had a few pumps fail.
I have checked the pump, and I'm 95% sure it isn't that, as I've had a multimeter plugged into the pump connector when the pump is and isn't working. When it is working, the circuit flashes 12v when the keys are moved to ignition 2, to prime the pump/engine. When it isn't working, there is no voltage coming across the circuit at all.
Will look for the relay in a bit and see if I can spot anything wrong. Not entirely sure how to get to it but I'm sure I'll figure it out

Hi All,
I've looked for the relay and found it under the ECU. I've had a look at the connections, and they look fine.
I've tried testing the resistance across the relay, by plugging into the connector at the fuel pump end. However I don't think I'm going about this in the right way. So how exactly do I go about testing the relay while it is in the car?
Also, this relay does not exist as an aftermarket part according to GSF and lucas Spares. So anyone got a suggested source around Exeter? Peugeot want £40+Vat hence me being so keen to ensure it IS the relay thats the problem, and not the ECU, etc.
Thanks

unless you can get relay to fail it is very difficult to diagnose,try going to a scrappy and getting one most of them are the same througout peugeot/citroen range on the side of the relay is a diagram of circuit just compare with your scrappy one,also the connection fixing is either a red slider or a piece of wire around the plug which i think is what yours is

Hi Mate,
I can get the relay to fail pretty easily by running the engine for five minutes, seems to cut out then...:S
The relay has the red catch you mentioned, is dead easy to remove. Am ringing round some scrappies today/tommorow to see if I can locate one in the vecinity. Unfortunately I can't drive there, but its well worth getting one cheap to see if its that, just incase. Would save me ALOT of money if I don't have to send it in somewhere!

I've got a replacement relay on the way via royal mail. Most of the scrappies I found with one wanted £35 odd + vat + del! Thats almost as expensive as a new one from pug! Luckily the first person to get back to me wanted £15, so this will do as a test. Also got my eye on an ECU error code reader on Ebay, so will aquire that just incase the problem isn't the relay (fingers crossed).
Thanks for everyone's help so far!

When the battery is reconnected the cars ECU will go back to the base factory settings.
It might be a sod to start at first & it will run odd & rough.
Dont worry about that, Thats what its ment to do.
Drive the car for about 30 minutes or around 15 miles & the ECU will re learn the engine & then run sweet

Cool cheers mate. Wouldn't start but thats because of the relay problem - still waiting on the replacement at the moment. Am also purchasing an ECU fault coder reader cheap off ebay at the moment to double check that nothing else has gone wrong!PowerLee wrote:No

ok. you can fault read ecu by earthing pin in diagnostic connector and light will flash a fault code. i think (long time since i have done one) earth pin for 3 seconds light will then flash once then pause then flash twice this gives 1 + 2 which is 12 start of sequence then earth again for another 3 sec then will flash another code.if it flashes 11 after 12 that is end of sequence and no codes were stored
