I hope someone can give me some direction, As in my earlier thread I replaced the intake gasket on my truck. While doing this I noticed the water ports on the intake were pitted up. I bought another intake complete with the fuel lines still connected, supposidly off a running motor. The truck ran fine, it just leaked water before I pulled my intake. All of the swap out is complete now, distributor is back in exactly as it was removed, I've done a dozen or so of these, but now it won't crank. It is firing and will crank if gas is poured into the throttle body. I know I need to check the fuel pressure, I know the pump is running, any other ideas on why it would run with the old intake and not with the new one? And what to do to fix it. Thanks for good suggestions.
