fuel pump fuse
« on: December 22, 2019, 09:27:06 AM »
 hi ..
 im trying to get my car to start..
 it worked fine then sat off road for a while but now getting it back on the road .  trouble is I don't get power to the fuse 11. I checked the relay and power is there but not from the fuse 11 for it to work. where does the power come from to get to the fuse.
I have tried swapping ecu  but still no power.  cold it be a break in the  wire?

 im lost here

I did by pass the fuse and the car turned over and the fuel pump got warm .. ( there is not much fuel in the tank and needs to be drained as its about 3 years old fuel..    should the pump get warm  ?

thanks

Hi!

You don’t mention which year or model but the main difference between older and newer models is the inclusion of the immobiliser circuits.

Fuse F11 is the fuel pump and it’s fed by the fuel pump relay. The relay has a permanent feed that is switched to feed F11 when the relay is energised.

The ECU controls if and when the relay is energised - you can test if the relay is energised when cranking with a simple multimeter - you’re looking for 12v on the relay coil.

Do you get any flashing lights when you put the ignition on?
