OK.
Its a complete wiring diagram.
But the diagram is huge.

I am giving you the same diagram twice.The same diagram is provided twice,because if first image is not clear,you can see second image.


So here is the diagram.
make sure you have, oil pressure , fuel pressure between 60 to 66 psi(nothing less, when cranking ) also check the fuel pump relay at the electrical center under the hood.
