Stephen Bearded Minky Hill Posted March 9, 2015 Share Posted March 9, 2015 Hi there. I drove home today fine, went to go out again and it started but then cut out. Tryed to start again and noticed no humming from the pump. I got rid of the cut out switch ages ago so I checked the connection under the spare wheel and put a bulb on it and nothing. Swapped around all the yellow relays, one under dash and two in the fuse box and still nothing. Has anyone got any ideas???? Quote Link to comment Share on other sites More sharing options...
Guest ANDYA Posted March 9, 2015 Share Posted March 9, 2015 The fuel pump fuse should be number 7, it's 20 amp. Check and see if it's blown. Quote Link to comment Share on other sites More sharing options...

Stephen Bearded Minky Hill Posted March 10, 2015 Author Share Posted March 10, 2015 All the fuses are fine Quote Link to comment Share on other sites More sharing options...
welshlad Posted March 10, 2015 Share Posted March 10, 2015 Small brown wire going to the negative batt point, mine was corroded and came off a while ago and can be another reason why the fuel pump isnt working as well as all the other obvious ones Quote Link to comment Share on other sites More sharing options...
Guest ANDYA Posted March 10, 2015 Share Posted March 10, 2015 Stephen, Â Welshlad's right. If you've checked for the obvious, you're going to have to trace the feed to the pump.You'll need a wiring diagram though. Haynes me be the only way unless there's a source in here. You could try tapping the pump with the ignition on and see if it kickstarts. Quote Link to comment Share on other sites More sharing options...
Guest ANDYA Posted March 10, 2015 Share Posted March 10, 2015 Also, check the work you did to get rid of the cut off switch. Quote Link to comment Share on other sites More sharing options...
Stephen Bearded Minky Hill Posted March 10, 2015 Author Share Posted March 10, 2015 Cheers welshlad. I've checked that small earth and that's all good. I've disconnected the battery and put a pack on the body and the wire in the boot where the cut out switch was that goes to the pump but still no pump but I traced the wire back to the relay and there's power. Going to drop the tank tomorrow and put power straight to the pump and see if it has died. Quote Link to comment Share on other sites More sharing options...
Stephen Bearded Minky Hill Posted March 11, 2015 Author Share Posted March 11, 2015 The pump itself works. It seems that the black box on the underneath of the plate on the top has packed up. Does anyone know what this is and if it can be bypassed? Quote Link to comment Share on other sites More sharing options...
welshlad Posted March 12, 2015 Share Posted March 12, 2015 Hmm cant see how that could of packed up as its only where the power wires pass through to get to the pump spade terminal ends.. is it corroded inside etc ?  You could drill a hole through it (and obviously use a rubber grommet to prevent the wire rubbing) and rewire a good length of wire through to some new spade terminals but the problem there is that fumes/pressure might escape if not sealed properly  Have you tried ebay/breakers as that top part should be cheap, without the sender/pump Quote Link to comment Share on other sites More sharing options...
Stephen Bearded Minky Hill Posted March 12, 2015 Author Share Posted March 12, 2015 No joy on eBay as yet but I'll keep looking. And all the local breakers haven't got one. If the wires just pass through it then it should work if I bypassed it. I've cut it and soldered it now and gonna try it in a bit Quote Link to comment Share on other sites More sharing options...
Stephen Bearded Minky Hill Posted March 12, 2015 Author Share Posted March 12, 2015 It's alive!!! God knows what that little black box was for because it runs perfectly without it. Thanks for your help people!! Much appreciated 😊 Quote Link to comment Share on other sites More sharing options...
jinks Posted May 30, 2015 Share Posted May 30, 2015 little black box has a resistor in it so keep eye I on your wiring it might burn Quote Link to comment Share on other sites More sharing options...
