Volkswagen Beetle 2000 190898 miles
2 L inline 4 2000 year. No fuel pressure unless you block the fuel return line. And a random misfire on at first piston 4 now on piston 1? the coil pack was replaced with new, new sparkplug wires, new temperature sensor, replaced the fuel pressure regulator. Problem persists... low to no power on acceleration can move car when rpms are slowly raized but only up to 3000 rpm. If you block the fuel return line can accelerate but the fuel pressure will remain at 80 psi, standing fuel pressure is at 38 psi; when vaccuum line to fuel pressure regulator removed the standing pressure goes to 48 psi.
No hair left on head because of scratching...
