I put a noid light on the injectors and am not getting any

Customer Question

I put a noid light on the injectors and am not getting any power
JA: Just to clarify, what are the exact lights you're talking about?
Customer: they have a light that you put on your fuel injector then crank the motor to see if the injector is getting a pulse from the distributor. they are called noid lights
JA: What is the model/year of your Chevy?
Customer: 1994 chevy Silverado 1500
JA: Are you fixing your Silverado 1500 yourself? What have you tried so far?
Customer: I have tested the relay switch . the ground is working but there is no power coming to the relay. I watched a video that shows how to use a jump wire to test the pump but I haven't tried that yet. so all I know is the injectors aren't getting power and the relay switch isn't getting any power
JA: Anything else you want the mechanic to know before I connect you?
Customer: just how I find and fix the problem

Hello and welcome!

My name is ***** ***** I can assist you with your question.

Expert:  AMEDEE replied 9 months ago.

Your saying there is no injector pulse while cranking the engine correct?

Are the injectors getting power with the key on and while cranking?

Does the engine have spark while cranking?

Can I start by getting your VIN?

Thank you!
