Got this waveform I took off a 2006 Pacifica was wondering if the fuel pump is on its way out or if I'm just seeing noise. Car doesn't have any symptoms but it does need a new level sensor I just wanted to play around and see what the current looked like on the pump. RPM calculation came out to 3,000rpms. I could be wrong. I'm new at this haha.

That's an ugly waveform. :blink: I wouldn't hesitate to replace it.

Thank you. Just wanted to be 100% sure. Weird how the waveform is this bad but there’s no performance issues present.

I think your 2nd cursor is 1 hump off to the right. Anyways that's not a textbook waveform :) Since you're replacing the level sensor I'd change the pump as well.

Yeah I got an assembly for the level sensor anyway. I just was curious of how the fuel pump waveform looked and wanted to play around. Thanks!
