Default Sc300 fuel system

I'm looking into doing a direct power line to the fuel pump since I can't seem to get my fuel pump to come on does anyone have a write up on how to do this?......... I checked every fuse,every relay, did the 12v mod,replaced the fuel pump and I still can't get my cars fuel pump to turn on..... Can someone give me some help?

the 12v mod should do that, there may be a more direct way but I have not done it. you could even have a bad pump if its not working with the 12v. Also check the fuse for the injectors.

Befor I installed the pump I turned it on just to make sure it was working so it's not the pump. I've already gone through every fuse and reley in the engine bay and kick panels it's not one of those either. The only option I have now is to hard wire the pump directly and I need a diagram.

It was the damn ground........ The 3 10mm bolts that hold the fuel pump hanger inplace are also the ground for the fuel pump all I needed to do was wire brush them off and it started right up.

Those grounds get me almost every time, no kidding. -_- Replacing the tranny, forgot to connect the starter ground. Gave my heart a racing when it didn't even try to turn over.
