Hi, I have a reanault 5 campus 1990, i had to change the fuel pump, now i can't get any petrol through to carb. have checked fuel lines, can blow air into tank but not suck petrol out, does it have a fuel filter in the tank that could be blocked? have tried everything i could think of desperate for help!

hi martin, you dont say why you had to change the pump.crank the engine to start it,you should hear it buzzing from the tank,indicating its working. a blocked filter will rarely stop the fuel completely, you would at least get a dribble. if the pump is not making a noise at all try slapping it with the palm of your hand,(sounds silly i know but it works sometimes if the pump sticks) check the fuse and relay. i think they are in the main box under the bonnet,(the fuse may be in the box inside the car i cant remember) see if there is a 12v feed to one side of the fuse if not i think your fault may be with your immobiliser. it work by shutting the fuel system down, and play up on these cars for a passtime. if fitted, see if your central locking system is working, if not im sure the problem is with the immob. hope this is of some help. i dont know how to read replies on this site im at ,paddycanman@hotmail.co.uk best of luck
