Are Fuel Injector O Rings Universal? This Dorman – Help Fuel Injector O-Ring Assortment – Universal (Part No. 90100) is universal and not vehicle specific. Are all injector O rings the same? All the O rings that are the same O diameter and wall diameter are all the same. Do fuel injectors need special O
What Would Cause Injectors Not To Fire? So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors. How are fuel injectors triggered? The Injector It is supplied with pressurized fuel by the
Where Do Fuel Injectors Leak From? So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an
What Controls The Injector Pulse? The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors. What causes no fuel injector pulse? When these fuses blow, the system they support stops working, and the engine stops running. As a result, there is no injector pulse while craking.
