Pressure drop....

There is a black plastic plug in the side of the manifold. The MAP should
be hooked up to one of the three outlets on that plug.

All other ports on the manifold that don't have hoses
hooked up to them should be blocked off.

If you can get the motor to start and run, then you obviously have spark
and fuel. But if you don't have any fuel being returned to the tank, then
the chances are you don't have enough flow/pressure in the rail.

The pump needs to be able to maintain better than 30 psi in the rail at idle,
and around 40 psi at WOT, otherwise the injectors will be under-fueling.
Maybe you need to get hold of a pressure gauge and get some actual
measurements on what is happening at the rail ??

Cheers... jondee86
