The process of identifying the injector signal is lost,
Found in the state of a connection was found connector is untested check the ECM
Where are you going this connector is connected?
Please confirm,
Thank you.

I will guess this is for the original radio that was removed from the car. The many splices in this picture make me think a new radio was installed, and this original connector is not used.

What year is this car? It looks like it could be a connector for a very early THEFT MODULE. I'm quite confident that is what it is. Mention year and I can give you an image maybe of location.

Here's from an '84 - HRR (Hot Rod Roy) should be able to help if you've questions. Your connector has maybe 13 cavities? I thought '84 but thought better to ask.
Where are you located?

It must exactly match the picture.
However, there is no module.
Is there an injector signal for this?
Or it is or may not be mounted in the first place?
thank you for your reply.

Yes, WVZR-1 is correct. The colors of the wires in the picture are correct for the Theft Deterrent Control Module in the '84 Corvette. This module has nothing to do with the injector pulse.
All of the plastic taped wires in the picture is not good. There has obviously been a lot of rework done with these wires. If you are having trouble with a fuel injector pulse signal, you need to test the wires at the ECM unit. The light blue wire (pin 8) and the green wire (pin 9) are the injector pulse wires. These are the same wire colors that connect to the two fuel injectors.
Have you confirmed that you have 12 v. on the red wire and on the white wire at the two injectors?

Are you missing the injector pulse from only one injector, or from both injectors?
If you are missing the pulse from both injectors, your problem is probably elsewhere. It is not likely that you would have two broken wires!
Do you have good ignition spark?
Do you have the 1984 Factory Service/Shop Manuals (FSM)?

Both the signal does not come up to the injector.
looks like sparkplugs is nomal condition.

And I don`t have manuals.

The video tells me the injectors are not spraying fuel. The problem could be no pulse to the injectors. There are other possible reasons. How did you determine there is no pulse signal to BOTH injectors?
With the ignition on, but the engine not running, do you have 12 v. on all four wires on the two fuel injector bodies?
The problem could be low fuel pressure. Has this been tested?
Is the fuel filter in good condition?
Are you sure there is adequate fuel in the fuel tank?

Hello.
sorry. to late reply.
Replacing the fuel filter, the fuel pump new.
The power does not come to the injector body 12V
However, when the supply of electricity to the injector is activated to force.
And not much fuel in the fuel tank.
Fill the fuel in the fuel tank.
Thank you,

Test the fuel pressure:
1. Remove the old fuel filter.
2. Install fuel hose in place of fuel filter, with "T" in center of fuel hose.
3. Connect pressure gauge to "T".
4. Apply 12 v. to ALDL connector (under dashboard, near steering column) pin G. Fuel pump should run. Measure fuel pressure.
Check the INJ 1 and INJ 2 fuses in the fuse panel at right end of dashboard.
With ignition on, do fuses have 12 v.?
Apply 12 v. to red wire or white wire ONLY!! 12 v. to other injector pins WILL DAMAGE ECM!!
Are you saying you see fuel spray from the injectors?
Good news!
