Fuel pump problem

[jnor]

I replaced my fuel pump today,and now I only have 20lbs of fuel pressure.

The pump is a new GM.
The car will barley run. Does anybody have any ideas?

Thanks

Did you replace the filter, maybe its clogged? Make sure you didnt pinch a fuel line when you installed the pump. Why did you go with a Gm pump?

I bought a pump from Kirban, it didn't have the adapter harness with it and I was in a hurry.

Looks like I might as well wait for the harness.
