ive got a 1.4 breeze hi torque and the fuel filter stopped working i have replaced it with a different 1 which was working when i got it and it still dosent work. i had a diagnostic done on it and the guy said that the ecu is frazzled and the fuel pump is connected to it thats why it aint working any more has any 1 had this happen

ps im after a replacement ecu and key chip (for the immobiliser) if any1 has 1 cheers

Hi mate fuel pump is controlled to the ECU but is turned on and off by the fuel pump relay so it could be that this is at fault and check the wiring to it.

Don't pay for a diagnostic mate do the paperclip test its free

If you disconnect your battery for an hour or two it will reset the ECU, then try starting the car and it will record new fault codes then do the paperclip test.

WARNING DISCONNECTING YOUR BATTERY WILL RESET YOUR STEREO AND YOU MAY NEED TO ENTER A SECURITY CODE TO GET IT TO WORK.

If you still have no luck then your gonna have to search scrap yards for a corsa with the same engine as you that has a key for an ECU

hi mate where do i fand the fuel pump relay not sure where it would be

i totally 4 got about the paperclip test haha ive ended up parting with 55 qwid alltogether for the heap of shizzle not including the new fuel pump the guy told me to fit
ill try the test like

Its near the ECU, If you take off the plastic panel on the right of the driver footwell you will be able to see the ECU the Fuel pump relay is purple.
It might be tooked out of the way but its just a little purple box on its own thats plugged into some wires, try swapping it with one from a mates car or get one from a scrap yard, but also check the wires look good they might be shorting or grounding somewhere.
