  1. Yeah, it was low-around 40 when running before I switched the pump, now it's up where it needs to be.
  2. Hey there guys, I'm having some trouble with my 2000 Silverado starting hard when it's warm and been sitting for a little bit. It's a 5.3. I replaced the Fuel Pump with a Delphi FG0407 and a new fuel filter as well. I had put a new fuel pressure regulator on it, but it didn't make a difference, so I put the old one back on. Doesn't shoot gas out the vacuum line either. I also cleaned the injectors and injector o rings, put new NGK Iridium plugs and new wires on it too. I cleaned my MAP sensor and tested it, it is functioning correctly. I also cleaned my throttle body. Put a new MAF sensor on it a little while back, have cleaned it recently. Cleaned the air filter a little while back.Cleaned my idle air control valve. Put a new Engine Coolant Temperature Sensor on it as well. Does anybody have any advice for me? If it's a cold start, it starts right up. Runs amazing. No problems whatsoever besides the warm starting. I just don't know where to go from here. Any advice is appreciated. Thanks!
