Fuel Pump Question

[stuart1298 6]

Right my cars over fueling, turns out the bloke before me had some how wired the pump to the electric window live, I assume the fuel pump relay packed up and he cut all of that bit of the loom our and wired to that. Semi sorted out, but the fuel pump now comes on, on the third 2nd click, just wanna check this is right, and I it's meant to stay on for a second after the ignition is turned off

is it possible to wire up a fuel pump the wrong way so it over fuels an engine? i thought it was just a case of getting 12v to it (+earth) ? i have mine on a switch which goes to a fuse and then the battery.

as far as i know the fuel pump doesnt make an engine over fuel? as the regulator conrols the pressure in the rail

thats what i thought, here is what autodata says.

I always thought fuel pump was On or off

Cheers, will try get gold of a regulator the sensor is coolant sensor is new, not to say it's not faulty tho.

[jonnyturbo 3]

is it overfueling from cold start too or only when it gets warm?

[stuart1298 6]

not to sure to be honest, it smells fuely, and 2 of the plugs have the colour from when they over fuel.

 

just put a post up to identify what of the 3 sensors is the one for fuel, so gonna get a new one

if its specifically over fuelling (or apprears to be...) on two cylinders them it wont be the fuel pump, though it wont help general running if its playing up.

 

it may be a spark or wiring issue . possibly that two injectors arent firing at all?

It seemed like to, but i'm not 100% someone looked at it for me, i think i have the wrong coolant sensor , just been looking in to it, and it seems it may have the wrong one
