No start due to fuel, please look.

Can I just ask why your are running a fuel pressure of 43.5 on a 1g? Stock FP is 37 and there really shouldn't be a need to change it, even with E85 I believe. Increasing your fuel pressure past stock won't really do anything, might cool the engine a little bit more but from what I know it should be at 37psi.

And I would bet that the reason your FP wiring failed is because you are running a walbro 255 on stock wiring, and don't try to tell me that it can handle it because it can't obviously.

Most injectors are base flowed at 43.5psi. So for setting up global on link the ideal base pressure is 43.5.

As pointed out, setting the fuel pressure at 43.5psi is what the injectors are rated at. When you run them at the stock 1g 36-37 psi base fuel pressure, you are effectively making the fuel injectors smaller.
