Can a fuel injector be unclogged while in the engine?
Although there are many products such as injection cleaning additives that claim it can clean or unclog a clogged fuel injector while it is in the engine, they cannot. For any of these products to work they actually have to get inside the injector.
What’s the best way to crack an injector line?
Once the spurting fuel is consistent (not just random bubbles), use the 5/8″ wrench to tighten the end of the injector line on the injector. The quicker you torque it down, the less likely the fuel is going to work its way out of the crack, and the less likely it will lose its prime.
Is there a drain plug on the fuel tank?
Note Not all vehicles will have a drain plug on the fuel tank. Before beginning be sure to research your specific vehicle to see if it indeed does have a drain plug. Step 1: Drive the vehicle until the fuel is as low as possible. Similar to Method 1, Step1, this will cut back the amount of draining that will need to be done, saving time and energy.
When to torque down diesel injector lines and purge air?
As soon as possible, torque down the remaining injectors. Any delay will result in diesel fuel spraying all over the engine bay. There may be a few minutes of a rough idle, because remaining bubbles might need to work their way through the injectors. At this point, the IDI should be idling.
How do I know if I have a bad coil or bad fuel injector?
You would simply unplug the injector, plug the noid light into the harness for the injector, and when the engine is started, will show a light when the pulse to the injector is present.

How does a coil pack work in a car?
Coil packs usually create a better spark, which in turn produces better combustion and horsepower in a car’s engine. How a Coil Pack Works When creating a spark at the spark plug, the fire must initiate from a high voltage supply, so as much fuel as possible burns in the cylinder.
How does the injector pump work in a diesel engine?
The Injector Pump (IP) creates hundreds of PSI of pressure in the injector lines. The injectors “pop” at a high pressure, which sprays diesel fuel into the cylinder head. If there is air in that injector line, the IP output pressure is padded by the bubbles and the requisite high operating pressure is never achieved.
