gt500biatch Posted January 22, 2013 Author Report Share Posted January 22, 2013 right, back to square one haha it wont start again... i used the multimeter to check the ecu plugs, the fuel relay pin lights up but bairly where as the otherones light up instantly and nice and bright.... does this mean it is the relay wiring or is it meant to be like that ?

gt500biatch Posted January 22, 2013 Author Report Share Posted January 22, 2013 found out the issue, i jump started the fuelpump relay, i get 40PSI fuel pressure and the car starts. faulty wiring to the relay. thanks everyone for the input and i hope this helps someone down the line :) Cheers Owen Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted January 22, 2013 Report Share Posted January 22, 2013 It depends which pin it was, you'd need to know the circuit to tell what it should be like. The relay circuit is often printed on its side or base. Maybe the relay could be bypassed with 12V direct from the battery & see if that starts it.

gt500biatch Posted January 22, 2013 Author Report Share Posted January 22, 2013 its the blue wire which powers the fuel pump, bypassed the relay putting a wire from that one to the red/white wire which starts it, it runs the fuel pump constantly so when i stop driving i just unplug the bypass wire. my sparky mate is gna come fix it this week sometime. atleast i know what is wrong now ! haha Quote Link to comment Share on other sites More sharing options...
