Check your low fuel pressure system's filter. These may be located on the frame rail or close to the fuel tank. It should be fairly evident if the fuel filter has been replaced recently or if it looks like it has never been changed (or not for a while). Replace accordingly. Keep in...
The Fuel Pressure Sensor (FPS) is usually found directly mounted into the fuel rail, close to the injectors and the intake manifold. The FPS converts the system fuel pressure into an electrical signal for the Powertrain Control Module (PCM). The PCM receives this voltage signal and possibly o...
I am chasing a very slight consistant stumble at idle. I am getting 28psi off the fuel rail. When I unplug the vacuum hose off the fuel pressure regulator I get 38psi. Tu...
POLARITY CONTROL AND CABLE SIZES With the engine off, connect the electrode and work cables of the appropriate size (see the following table) to the studs located on the fuel tank mounting rail. For positive polarity, connect the electrode cable to the terminal marked "Positive". For Negative...
If the fuel regulator (1) and sensor/s appear to be functioning properly, use a manual fuel pressure gauge to test actual fuel pressure at the rail in an effort to duplicate the failure condition. Fuel rail and related components may be under (extremely) high pressure ...
Even though most studies and enterprises have focused on ethanol as a fuel rather than butanol [35], butanol may be a significantly superior direct option. Because n-butanol has a lower Reid vapour pressure than ethanol, it is less evaporative/explosive [7]. Because the air–fuel ratio and ...
