This is a 0-4-ter-angle fuel pump. I was having troubles. It would not start the vehicles double checking the old one to verify that that was even the problem. What you could see is we went ahead and just submersed the fuel pump here in a liquid, just water in this case, just trying to be a little safe not have flammable. Then out of the outlet, we're just going into a bucket here. You could see here, as you trace the wires around, you've got two going to the pump. You point to that for me. Two going to the pump and then you got two going to the float switch for your fuel level gauge. We just need to supply a power and ground to that little electric motor. We talk about all the time, power's in, and ground's out, and we're going to see what happens. We have figured out and here our ground is on the left hand side with the brown wire and our hot coming in from the, or two, the pump is our one on the far right, which is our hot. We use a power probe, hooking up our ground to our ground side, and then we are hooked up to an external 12 volt battery. Quick thought I wanted to drop here is consider this as polarity sensitive. If you hook those wires up backwards, the fuel pump would operate backwards. You really want to know the polarity of what you're working with so you can just try to test it in the operation that it would normally function in. Off the bench, we put it on through our hot and we see a green light so we knew, we do have ground going through. Okay, stop right there. So that means that we have power going in. It's a continuity checker out that ground wire back into the power probe and out of the power probe, we have the wire going back to a ground. So that light being lit, like CJ says, means that we have a good ground. We're always wanting to look for that. We have a complete circuit. Complete circuit. You got it. All right, let's go ahead and fire it up. Okay, and let's see what happens here. Do you hear something? Yes, it is. It's physically trying to run, but there's nothing coming out. Okay, and you can see, get a little bit out of there. This is a fuel injected vehicle. So we know this thing's going to have 50 to 80 psi or something like that. Yet something else happened in there. Do you see where that light is flickering? Go ahead and take the power probe off. Now just do it in the air. What that shows is the supply voltage that we have available. Now when you engage that, go ahead and do it on the pump again. That flickering light is not good. That would indicate a bad connection or maybe even under load, poor insulation on the wire. We want a solid red light when doing load testing. CJ, it looks like you were placing your pump was absolutely needed. Keep your engine. I hope you found this video useful.
