mellonman Posted July 3, 2012 Share Posted July 3, 2012 alright after fittting my new walbro 400, the car wont run its seems to be voltage related so was wonering at what point do you need to bypass the fuel pump ecu? i dont even think i can hear this one prime.it get 6v while starting and then just drops to 0v and cuts out im not sure if its drwaing to much current or what .any input on this matter would be great Quote Link to comment Share on other sites More sharing options...
Alex Posted July 3, 2012 Share Posted July 3, 2012 You never need the 12v mod on a stock ecu/turbo's. What you might need though is to beef up the wiring for the draw from the 400. To be honest it sounds like you've got a dodgy connection. Quote Link to comment Share on other sites More sharing options...
