Will not start, fuel injection issue

Hi,

Here is what I need you to do. Each of the fuel injectors should have a red wire. These wires should all have 12v when the key is on. I need you to first check that.

I apologize for the rough schematic below. However, note that the injectors all get power from the same place. What actuates them is when the PCM provides a ground path to the specific injector. If we have no power, that is where we need to start.

Let me know what you find.

Take care,

I rented a node light test kit. With the key on the light did not light but when try to start the light pulses.

Hi,

With a Noid light, which is exactly what it should do. So, I realize the fuel pump is new and you hear it working. However, have you confirmed the fuel pressure is within spec? If it is too low, it could cause an issue.

I would suggest checking each fuel injector to make sure the light pulses to make sure. If you have already, then it is likely a pressure issue. It could be the injectors, but for all of them to fail at one time is a bit difficult to believe.

Here is a link that explains in general how to test fuel pressure:

I attached the manufacturer's specs below for you. Something is preventing the fuel to make it to the injectors, or it is too low.

Let me know what you find.
