Back to the fuel pump.

Dash has c41 error.  I have checked:

• the relay and also swopped with others and all seem fine
• G/W wire from relay which goes to the ecu and that’s fine,  connections are good and no short.
• BBR from the relay for the fuel pump circuit and injectors and that’s fine too.
• Injectors test as per manual and they seem fine, resistance was a little out but don’t know how much the temp affects it

The pump had previously seized, could this be causing the C41 error.   The error appears with or without the pump attached.  Power has been disconnected for a few days and error not cleared.

The fuel pump runs.  But constantly, is this correct?

I think I’ll have to get a pump and see what happens.  if that doesn’t work then I fear that when the pump stalled something must have affected the ecu.
