Why is my fuel injector not working properly?
Another common problem with fuel injectors is the buildup of fuel varnish deposits in the nozzle that restrict fuel flow or disrupt the injector’s spray pattern. On many late-model engines, the shape and direction of the spray pattern is critical for clean combustion and good performance.
When do you assume there is enough pressure in the injectors?
If the engine runs, they assume the injectors are getting adequate fuel pressure. If the engine cranks but won’t start, and they depress the service valve on the fuel rail and some fuel squirts out, they assume the injectors have pressure. They do, but the question remains, “How much pressure?”
How do you test a fuel injector ( ANS )?
Ans: By using a simple diagnostic tool called NOID light, this tool detects a digital signal coming from the ECU and flashes an LED light, so if there is no LED flashing during cranking, this means that there are no pulses coming out of the ECU. Question: How do you test a fuel injector?
What does it mean when there is no injector pulse?
In case of that, there is no injector pulse or spark, this means that is your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.

What causes an error message on front injector?
Error Messages 31 Front (Or Back) Injector Incomplete Injection Probable causes • The syringe needle is bent. • The plunger or syringe carriage is operating incorrectly during injection. Suggested actions 1. See Correcting Syringe Problems on page24. 2. Remove the syringe from the injector, and check the plunger for stickiness or binding.
How to troubleshoot an Agilent front injector error?
Suggested actions 1. See Correcting Syringe Problems on page24. 2. Remove the syringe from the injector, and check the plunger for stickiness or binding. Replace the syringe if necessary. 3. Restart the sequence. 4. If the error occurs again, obtain Agilent service. Front (Or Back) Injector Reset Probable cause
What causes no power to fuel injectors?
The most important signals that determine the accuracy of a signal coming out of ECU to injectors are crankshaft position sensor and camshaft position sensor, so to test a bad injector, you have to check the voltage on the injector when the ignition key is turned on: NO VOLTAGE? , so what causes no power to fuel injectors?
What to do if your injector door is open?
• The line voltage to the GC is off. • The injector cable or connection to the GC is bad. • Your GC requires service. Suggested actions 1. Verify the injector is properly connected to the GC. 2. Check the power source for your GC. 3. Obtain Agilent service. The Fault Light Is On Probable cause The injector door is open. Suggested actions 1.
