Hi guys & girls,

Went to start my car the other night & wouldnt fire... got the nrma out & said the the fuel pump is gone. its a holden 5litre v8 & was wondering if any pumps off any of the commodores will fit it.

cheers garth

do v8's have two fuel pumps. if so, it is a bit strange that both are buggered. could be something else. maybe there is no power getting to the pumps

 

[Immortality]

yeah, the V8 have the intank pump as well as an external booster pump. i'd go with defa, not likely both have failed. check fuses and relays etc

It wont run on one pump, if the intank dies the lift pump cant pull fuel. If the lift dies it blocks the flow from the intank. They both go around the same time normally
My intank went, they around 2 weeks later the lift one went. The intank is the same as the V6 ones and the lift one if the same as a VLT.

I second that i had to replace both of mine within a week of each other when my car stoped.

To correct myself......it will run to some extent, but will have limited power and stall heaps annnnd burns the other pump out as its working twice as hard.

 

[defa]

well that all makes sense.. i would be checking if either are working and going from there..

yeah he checked all the fuses & they were fine... it has 2 fuel pumps... but when the ignition is turn to the on position it doesnt pump fuel (no noise) is there a difference between the vl turbo & non turbo? & how hard are thery to change

 

[greenfoam]

What model Commodore is it? in a VP I'd also be suspicious of the immobilizer switch in the passenger door

Has to be the turbo pump, the N/A one wont flow enough.
