Its the pump. Sorry someone more knowledgeable didn't come in here sooner.

The stock rated fuel pump can put out 80psi when its fresh. Pressure regulators lower the pressure when they're working. When they aren't, the pressure is high. Your problem was never the regulator, it's always been the pump.

Did you recheck your fuel pressure #'s after installing the new pump? I'm curious what they are. As said before, you should attain optimal pressure(mid 30's) as soon as the pump turns on. You were getting readings of 10 before.

One last thing that could cause a drop in pressure is the pump feed hose. The 3 inch section of rubber hose that connects the pump to the pickup tube. If that leaks, you'll have a pressure drop like you've described.

I havent checked fuel pressure again but now i have to! When i changed the pump i also changed the feed hose because the old one was terrible, so cant be that. How about spark.?

Don't jump the gun yet. Verify the pressures are correct. See if you can get a distinguishably different pressure tester, just to be sure.
