Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
the fuel pump relay is in the under-hood fusebox ( see image)
and if thats OK then check the if the ECM has got power as this powers up the fuel pump
that matchs the 1st image
check the EMS relay and the TCM relay as the next step as the 2nd image I have is the alternative
OK if they're OK have you tried running a wire directly from the battery to the pump?
as if it then sparks into life you know the pump is OK
Ok to get that variety of codes I'd say that there may be a lack of battery voltage or a poor earth connection
so I'd 1st measure across the battery terminals as voltage should be at least 12.5V and then with a runnnign engine rise to about 13.5V
and also check the main battery connections at both ends for cleanliness and tightness
also running out of the loom there should be a couple of small wires that use ring terminals and small bolts to secure to the engine
these are the dedicated ECU earth wires and also need to be clean and tight
do you still need help?
