as above where do I start to sort this out [/code]

 

fule cutoff

 

checked the cut off switch its not that

 

when you say no power to pump do you mean there's not actually 12V+ at the pump? or simply the pumps not working? does the pump prime?



fuse blown ?

relay blown?

pump completely died?

ECU or Wiring issue.



Think thats all it can be.

 

no power at all at pump car.
ran when i powered the pump off a jump pack tho so its not the pump

 

I've put up a link to a post that may help in the Sierra section

 

nice one thanks smidsy
