Where's fuel pump relay

[PlenumBiscuit]

So where is the fuel pump relay

VE series 2 Calais

It's not under the bonnet, not in passenger footwell (there's a blanked area for one) and there are no relays in back above the battery

Below the Battery Base.

Yes, remove the baseplate, and flip it over,
and you will find Fuel Pump Module mounted the bottom of it.

What really? Lmao

Is this a trick

fuel pump control module

mine is a wagon will it be there too

will it have a relay on it? or is it a next level encapsulated module

yes i suppose i could have a quick look with me torch (flat batteries though)

 

[PlenumBiscuit]

here i suppose

ever much issues with these? do they cost much new?

im still having issues with car staggering shaking up hills

maybe its compression, other wise its fuel related

 

[07GTS]

it controls the fuel pressure for curtain conditions when the ecu needs too, what are u trying to do with it ?

 

[PlenumBiscuit]

ive been wanting to simply change the fuel relay and hope the car would function better (chasing a fault)

but no it doesnt have a relay now? it only has this control module?

GM Fuel Pump Control Strategy

GM has advanced their fuel pump control over the years for the better, moving away from relying on a traditional mechanical regulator to control pressure and making environmental assumptions about operating conditions. Lucky for us, newer vehicles all use an actual fuel pressure sensor now so...

Yes just another computer on the car that can be updated or fail at anytime.
HP Tuners warn quite correctly to not program them as they are by far the most brickable module on the car.

crazy really, such a specialized extra computer you'd think would make it highly economical

i guess if it was faulty it would throw a code?

trying another one hope it doesnt have to be tuned
