Most likely the problem is not with the injectors, but with the high pressure fuel pump. A qualified repair shop should be able to test the output pressure of the pump.

It means you injectors are clogging up (Sprays gas in motor) Go to parts store...Buy bottle throttle spray...not carburetor spray because it eats your rubber ceils up. Take the air duct loose from carb. While accelerating you gas throttle with your hand spray the bottle throttle spray directly into carburetor. As the car trys to stall let go of the spray...Repeat 3 or 4 times.......Ive seen the engine light go back off after doing this...It will get to your injectors and clean them...Ive done this alot myself and what a diffrents.Its works alot bettef that just adding injector fluid to gas...Promise

Why is my tbi injector spraying too much gas? But wont start

You did not give the year make and model, so here are two general questions.
Do you have two injectors and are both flooding the intake ?
Can you unplug the injectors and stop the flow ?

I changed the fuel pump,im getting gas to the fuel rail but none to the injectors

If gas is getting to the fuel rail, it is getting to injectors. If fuel pressure is good, probably the injector circuit is not working. With a test light you can check the injector circuit. Post back for further help. What year and make is the car?

Has fire and is turning over strong but wont start

Probally not getting any gas. Turn your key to the start position and listen to see if you hear your fuelpump come on. It should be a humming noise for a few seconds then cut off by itself. If you hear that then your fuelpump shouldn't be your problem.You should have a valve pin on the fuelrail to the fuel injectors. Remove the small cap and depress the pin on the inside and see if gas squirts out. Do this after turning the switch to the start position. If gas squirts out then your fuel injectors are probally not spraying. Take out your #1 sparkplug according to your firing order which should be labeled somewhere under neath the hood and check it to see if it has any gas on it after a few times trying to crank it. If it doesn't then your fuel injectors are not spraying.

Old j reg mercedes 230te wont start

Check Injectors spraying Fuel when you start. Fuel pump prime because you hear the pump. IF pump is weak, then your Fuel distributor doesn't have correct pressure to spray fuel when injectors open. Do your sparks plug wet after trying several times. If they are dry then you don't have fuel. Replace injectors If they are wet then you don't have correct air:gas ratio of 14.6:1. Replace Fuel distributors

I am getting fuel to the tbi but it wont spray through the injectors please tell me what is wrong with it

Add techroline fuel injector cleaner and replace your fuel filter to increase the flow of gas to the injectors. You may need to repeat the cleaner until the injectors are clean.
