If the pumps are both running but you have no fuel pressure, you could have a problem like I found with mine, but you have to pull out your pumps to inspect them.
My car was having a problem making it crank a longer time to start. stumbled a little on acceleration, had a little low fuel pressure. When I pulled out the pumps I found that one of the original plastic hose clamps was loose, the hose was able to slide up and down, and fuel was obviously leaking back into the tank instead of being pumped out to the fuel rail. I changed all those black plastic clamps to SS screw clamps, stopped the leak, and all is well since. So check your pumps and make sure all the hose connections are tight and that one didn't come off somehow or have a leak in it. It could be something simple like that.
