My 2005 Nissan 50 forklift has a 2.5L four-cylinder EFI gas engine and seems to have a fuel starvation issue. The fuel pressure is only 26-28 PSI. What should the correct Nissan forklift fuel pressure be?
Yeah, 26-28 PSI sounds a little on the low side. I'd probably start by checking the fuel filter and pump first, since they're often the first things to cause fuel starvation headaches.
Yeah, that pressure does sound a little low, take a look at the fuel pressure regulator and make sure there's nothing restricting flow in the fuel line. Sometimes it's the simple stuff that causes the biggest headaches.
