How do you service a fuel injector?
During a full fuel injection service, several things are done: your fuel pump’s pressure and volume is checked; your pressure regulator is checked; your fuel rail, which is the pipe that sends the fuel from your pump to your fuel injector, and fuel injector screen is flushed; your fuel injectors are flushed and cleaned …
What do you do with a fuel injector?
1) Remove the fuel injector from the unit. And after that, cover the hole, with some cloth, so that nothing goes inside the unit. 2) Put injector in bucket and take it to the workshop. 3) Do the pressure test first, on the equipment provided on board.
How do you test a fuel injector feeding circuit?
You can also test the injector controlling circuit using a noid light. This is the easiest way to test an injector feeding circuit. The noid light connects to the harness of the fuel injector you want to test. You can loan or buy a set of noid lights from your local auto parts store.
How to check the fuel spray on a TBI system injector?
You can visually inspect the fuel spray on TBI system injectors. Fuel flow spray is readily accessible, making it fast to check for potential problems. Remove the cover off the air cleaner housing (where the air filter lives). Ask an assistant to start (or crank the engine, if it doesn’t start). Check the spray pattern coming our of the injector.
Can a throttle body fuel injector be inspected?

How do I change the amount of fuel injection?
In order to change the amount of fuel it applies, you must go to Go EFI Tuning and then find Fuel Cut Control. Inside this menu, you will see an option called DFCO Return fuel. This number represents the amount of fuel the system will inject when you start to give the vehicle throttle again.
What are the advantages of a fuel injection system?
Fuel injection systems have several advantages over carbureted systems. With fuel injection, each cylinder gets an almost identical amount of fuel. This helps each cylinder put out an equal amount of power. This in turn makes the engine run smoother and more efficiently.

How does the fitech fuel injection system work?
All Fitech EFI systems have learning procedures that the system uses to adjust the active fuel tables it is using for operation. Sometimes if there are outside problems such as bad misfires, exhaust leaks, or any other situation that could cause poor readings on the O2 sensor, the system will try to compensate in order to keep the car running.
