What causes a blown injector?
Poor quality fuel gets in the way of the injection process because it contains impurities that build up in the fuel system over time. These impurities can clog the fuel injectors, leading them to perform poorly or even fail. Anything from dirt particles to rust and even water in the fuel can block your system.
What are the symptoms of a bad fuel injector?
Fuel injector symptoms for bad, faulty, dirty, clogged, or leaking injectors are : Starting issues Poor idle Failed emissions Poor Performance Engine does not reach full RPM Increased fuel consumption Rough engine performance Surging and bucking under various throttle loads Smoke from the tail pipe
What happens when a camshaft position sensor goes bad?
This data is then sent to the powertrain control module (PCM) for use with fuel injector and/or ignition system control. When your camshaft position sensor is faulty or starts having issues, the first thing you should notice is that your “Check Engine” light comes on in your dashboard.
What causes a fuel injector to leak over the engine?
This can become hard and brittle from the heat of the engine. If it breaks, then fuel can leak out over the engine. This can be dangerous and is a common cause of engine fires. The other way an injector will leak is if the injector body or nozzle cracks. 3. Internal Part Failure – What causes a fuel injector to fail?
Why is the fuel injection computer not working?
In addition on some makes, like Chrysler/Dodge/Jeep, the Fuel Injection Computer will not continue to power the Fuel Pump or the Ignition System with 12 Volts after an initial ten seconds or so. What Tools Do I Need To Test The Crankshaft And Camshaft Positions Sensors?
Can a bad camshaft sensor cause bad engine performance?
Bad Engine Performance – A faulty camshaft position sensor will cause an improper amount of fuel to be injected into the cylinder chamber. The engine will not respond very well to this because it depends on a proper mixture of air and fuel to function adequately.
Can a camshaft be installed in a fuel injected engine?
A) Short duration, 220-222 degrees @ .050? maximum. B) Wide lobe separation/centers, 112 to 114 degrees minimum. Do not attempt to install a camshaft with a 108 lobe separation in a fuel injected engine, unless you are planning to re-program the ECM computer.
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 injector will leak is if, the injector body or nozzle cracks.
How does the fuel injector work in a Ford?
The engine draws in oxygen by way of the air intake and fuel from fuel injection. There must be a balanced mix of air to fuel in order to get an efficient mix. This is regulated through sensors, your Ford’s engine computer, and the injectors. The fuel injectors are electronically controlled by the car’s engine control unit.
