just finshing off my rebuild. the fuel pump doesnt prime when ignition is on i have checked the voltage at the relay i have 13 .8 v feed and the same coming out ofthe relay . put when i check the voltage in the boot i get 1.27 v this is the reason why the pump wont work so does anyone have any ideas wht my cause the low voltage in the boot.

Is it just worth while just rewiring the fuel pump and running the trigger wire from the old one to the boot and postive ad negative from he battery

thanks Olly

a rewire of the fuel pump is a must on all cossies, so do it regardless

you should be getting more voltage then that tho, even if the wiring was shot. Have you check the fuel switch off in the spare wheel well?

Where did you check the voltage exactly????
There is a multiplug tucked up beside where the latch on the bootlid lock lands on, there is a red/black wire, this is the one you need to check.

thats the one i checked first its got 1.27 v to it

AS said just get it rewired, along with the fan/s.
1.27v will NOT however energise a relay, so will need a "trip" wire running to the rear, or wherever you put the relay, from the original relay position, the wire has obviously degraded terribly.
I would also run a complete new earth direct from battery to pump.
