welshlad Posted April 9, 2013 Author Share Posted April 9, 2013 ill take that one apart then and see if its corroded, strange tho how they swapped the colours around import or not i thought they would all have the same loom etc Quote Link to comment Share on other sites More sharing options...
welshlad Posted April 9, 2013 Author Share Posted April 9, 2013 Sussed it the Grey relay (it was on a purple holder) was melted so i swapped it for a identical one ( Grey with red F 68125 88AG 14512 AA) and the pump is making the priming noise woop woop! prob is the relay must be the wrong one or it wouldnt have melted any ideas if its ok to use or not ???

welshlad Posted April 9, 2013 Author Share Posted April 9, 2013 Finally got to the bottom of it all the grey relay in the purple holder was knackered so when i took that out the fuel pump (When ignition was on) actually made the priming noise. but still i was getting no fuel so i tried bridging the 30 and 87 terminals on the yellow relay/holder (which i thought was the injection relay??) and hey presto i now have petrol coming from the original in tank fuel pump, just gonna fit battery now and then hopefully it will start Quote Link to comment Share on other sites More sharing options...
