· The fuel injection system is a critical component of every diesel engine. This system pressurizes and injects the fuel into air that has been compressed in the combustion chamber. The functions of a fuel injection system include feeding fuel to the injectors, adjusting the fuel quantity, adjusting the injection timing, and atomising the fuel.
· Each solenoid valve is normally open, and it is only closed by an electrical pulse from the ECM during fuel injection and metering. the best way to check the ecm pulse is with a noid light. so forget that, removing the injector plugs while running is ok but the best way to check for a failed injector it to use a temp gun on the cylinders.
5 Common fuel injector problems symptoms + solutions.
Step 4. Locate the injector fuel lines that supply fuel to the injector. They are often gold in color and screw into the engine near the injector. Each injector has its own fuel supply line. Using a wrench, remove the nut that secures the fuel supply line to the injector you wish to remove. Pull the fuel supply line out of the engine with your.
· A fuel injector can be cleaned many times, but it will eventually wear out and need to be replaced. Fuel injectors in cars typically last between 50,000 and 100,000 miles. Thanks!.
· WEAK FUEL INJECTOR. A condition known as "lean misfire" can occur if there is not enough fuel in the combustion chamber. Lean misfire causes that only affect one cylinder include a dirty fuel injector, an open or shorted fuel injector, or a problem in the fuel injector ….
· 1. Fuel smell from the engine bay. One of the first symptoms of a problematic fuel injector o ring is a fuel smell. If the fuel injector o rings dry up or crack, they may leak fuel vapors that.

· 7. Press the injector into the rail until it stops. Attach the metal clip, if equipped. 8. Reattach the fuel rail. This can be tricky, but line up all the injectors over their respective holes, then press each injector until they slide into place. 9. Bolt down fuel rail. Reattach fuel line.
· Fuel injectors are used in all modern engines, and are a vital component in the fuel management system. A bad fuel injector will wreak havoc with how your engine runs, and will likely leave you stranded on the side of the road..

· A leaking injector pump is a common problem with vehicles over 150,000 miles. The injector pump itself has a good reputation, and if you are experiencing leaking from around the injector pump it is most likely caused by broken O-rings. These O-rings are very inexpensive and will more than likely fix your issue.
· A good injector should produce a, cone-shaped mist of fuel vapor. So, if you see solid streamers in the spray pattern or a solid stream of fuel, the injector needs attention. You should also check fuel pressure to see if; the pump is weak or the fuel pressure regulator is defective. A plugged fuel filter, can reduce fuel pressure.
· So I replaced the #3 fuel injector with a re-manufactured part. This solved the p (at least for a day or two) but I still was showing p. With the 306 I checked the spark plug cables and found out that the boot had been ripped and the spark was arcing out. So I replaced all three cables.
- Fuel injector O-ring failure can cause either a fuel leak on the fuel rail or an intake manifold vacuum leak on the intake manifold. All O-rings are replaced with new with our fuel injector cleaning and flow testing service. Dirty or clogged fuel injector micro filter

· 1. There are two fuel line retention clips. One blue and one white. The blue one was broken in half. 2. Two of the injector electrical connections had the red locking tabs broken off and are missing. 3. Worst of all. Someone broke off one of the bolts holding the fuel rail to the intake manifold and replaced the top half so it looked like it.
Almost all gasoline based fuel injectors are sealed units. The term: remanufactured, rebuild, reconditioned and or refurbished fuel injectors are misleading and a myth when it comes to fuel injector service. It will be cost prohibitive to take dirty or clogged fuel injectors apart, replace and clean internal components, re assemble and then reseal the injector.
