hey ppls

i need urgent help please.. i picked up my car from it being at panel beater for a month yesterday and it was screwed.. it was constantly stalling on idle.. you could drive on boost etc though but it as soon as it idled at the lights it would just die.. so i went back to them and we spent a few hours yesterday investigating it and aparantly the fuel pump must of randomly died.. evan though the car worked on boost.... so i had her towed home from the panel beater which was great...

anyways ive put my stock pump back on and she aint working still... the car wont evan start up.. I tested the stock pump with a battery and its definetly working...

i took the fuel filter out.. and started it a few times to see if any petrol would come out that pipe and none did :teehee:

it also doesnt make the priming noise anymore... So at the moment no petrol seems to be getting to the front of the car :D ???

anyone have any suggestions on what i should try ? im worried when they fixed up the panels at the back of the they screwed something with the fuel lines maybe :O

also the fuel pump fuse is fine..

and on the white plastic thingy at the top of the fuel tank.. i swaped those 2 pipes over incase i had gotten them wrong.. but still nothing..

Hey mate that difficult casue u checked all ligical points, maybe check the two electronic connect plugs on top of the fuel tank lid, If ur pump defifnetly works out of the car and its not ur fuse it seems some where there is a break in the electrics powering it. Id say if might be the connectors in the fuel tank lid.

Good luck

ive had a look and theres definetly not power coming from the electrical connector for the fuel pump.. i hooked the fuel pump upto the battery directly and she works like a charm :wave:

thanks

well thanks to jazzar33 ive found the problem :P:)

the panel beaters decided it wasnt important to put the ballast thing back in the car.. so theres a connector just hanging there...turns it is important.. :iluvff:

      You have the option to do this. Nobody but me ever did this (go slower, I mean) Everyone seems to fall victim to "This would be a great setup for you, but for me, I need a little more power..."

      Save yourself the headache of an alarm. Immobilizer on the signal side of the main EFI relays so it won't start is good enough. DIY killswitch is the same thing except instead of a nice passive system you need to remember to switch it on and off.

      Yeah, the advent of canbus was supposed to cut down on wiring weight, then some bright marketing wonk says "oh, look at all these wonderful tech gadgets we can cram in here now that we have this wonderous technology" and some arsehole safety legislator says "oh, look at all the wonderful surveillance and tracking gadgets we can cram in here now that we have this wonderous technology" and some dipshit young engineer who has grown up thinking that an extra 500000 lines of code is not a problem because storage is cheap these days says "oh look at all this wonderful shit I can do to one up those dipshit arsholes over at VW" and the Karens of the world all go "oh look at all these fancy things I can do on my screen (so long as I am not driving on a bumpy road wherein touch screens immediately become the single most stupid shit idea ever shoveled into a car) and my 19 zone airconditioning keeps my sweaty fat folds a bit less damp and the windows close themselves because I'm too fat and lazy to wind them up for myself and these reversing sensors would have been great if I'd paid attention to them instead of smashing them on the bollard while I was reversing and staring fixedly forward that day I went to pick up little Charlize from ballet" and the sweaty mongoloids who say "oh this wonderful collision avoidance technology with these 45 excellent radar antennae scattered across the front of my car mean I can tailgate like a methed up tradie at full speed with no fear because the car and the 35 airbags will protect me if it all goes wrong" ...... </shallistopranting?>
