Fuel Pump Not Priming

[shibby69]

g'day

put a walbro 255l/hr pump in my 32 gtst bout 2 months back, worked well had it tuned after the fuel pump was installed and the tuner said it was pumping in plenty of fuel and working fine.

the last 2 days it has just packed itself randomly and isnt priming.

could it be something besides the fuel pump?

any help would be good

thanks guys

could be a wiring issue

if your not sure that its the actual pump thats shit itself.. take the fuel pump out and put straight 12v to it and see if its working..

that would help u in eliminating one thing ??

give that a go mate

check your fuses and relays relating to the pump, I had a fuel pump fuse die and after a $200 tow i realised the cause was a 5c fuse and i had a spare one in the car

ooo completely forgot about the fuse lol good idea.

what can i clean the wires with before i solder them together again?

If you've got a multimeter check if you can see 11 or so volts at the pump when the ignition is on. Also, some models have 'fuel pump control module' that dies, and a direct earth will bypass the module and get you running again. AFAICT the module reduces the voltage to the pump by switching in a soft earth when high fuel flow is not required.
