Lb7 Fuel Pressure Regulator Problems at Deane Ball blog

Lb7 Fuel Pressure Regulator Problems. The rough/lope idle is caused by excessively high rail pressure at idle, if the cp3 is worn out there is no way it would cause high rail. This guide will demonstrate the procedures to install the lbz/lly fuel pressure regulator in the lb7 duramax. The fuel pressure regulator has a solenoid supply voltage circuit and a solenoid. I am looking for some advice to properly diagnose what appears to be a low fuel pressure problem. Watch for spikes in actual rail pressure that are higher than desired. If this happens, simply replace the fca and be on your way. At zero volts the fca defaults to wide open, which gives almost 26,000 psi of fuel pressure and the truck should fire right up. Every electrical device needs a properly functioning circuit to support the device. I noticed you mentioned possible compromising of the pump. The time taken to accomplish this. 1) will a faulty pressure regulator cause damage to the cp3 pump? When the fuel pressure is low, the signal voltage is low. Not shorts to ground or power,. If its dancing around that's your surging idle.
