Hard to say how strongly it would stop making power. I think its a bad idea to keep testing though. My first thought would be for you to verify that the pump is correctly installed (sealing gasket is properly seated and not split), and then if that's ok, then try another Walbro 255 because I have not heard of any other cases where high voltage has failed to work.
Yeah haha, i´ve already checked that the pump is installed correctly and it is, I installed a fuel pressur gauge today, and had 0 pressure, then i noticed i don´t have any power at all at the big red wire in the contact that plugs into the fuel sender unit.
I pulled the fuel relay 1 and 2 out and checked for power in the sockets and there is good power at 1 pin for each relay there, haven´t had time to check relay number 3 yet tho.
any suggestions?
god i love me some wierd electrical issues
