Fuel pump relay HELP

[JoeP01]

Hi there,

I was driving my Seat Leon mk2 TDI when the engine cut out. Once I was toed there was a suggestion it could be a relay issue as the fuel pump is working but isn’t getting a signal. Has anyone else come across similar problems with this model?

Thanks,
Joe

Something happened to my leon cupra -08, normal driving, then i came home and parked it. Then i shut the engine and tried to put back on but it didnt go on. Battery is fine.

P0304 cylinder 4 misfires, changed coils and spark plug. Still nothing. Someone said it could be the gas pump, but still not sure.

Why i replied to this, thought there could be something in common? How your fuel pump sounds when you put your key and electronics turn on. I tried to search videos of it but havent found any..

And circumstances have been pretty much -5 / -10 celcius, but car stays in parking hall. Even found water in cylinder 4, so spark plug was like swimming there, cleaned it and dried it first of course after i installed new spark plug / coils for every. Three of them was looking fine.

Check your ignition coil fuse!
