Re: Multimeter Settings
Thats what I thought too, I was really hoping that it was a plugged filter. I changed that and the regulator and the pressure did not change at all. Changed all the fuses/relays associated with it too, but nothing worked. That at least narrowed it down through process of elimination to the fuel pump. Then I read somewhere that a voltage problem at the pump can cause it to run poorly and I may have an electrical problem.
Through everyone's help here, I think it is safe to say that there is sufficient power at the pump, so hopefully it is just...

Re: Multimeter Settings
Awesome information. That is exactly what I was trying to figure out. Next weekend I will get the car back up in the air and get the pump changed. Thanks to everyone for your helpful explanations and links/tutorials. I am still very much a rookie with this stuff, but I have done more and learned more about electrical testing that I ever have before this weekend. Color blindness also makes electrical work difficult, but I can work around that.
Anyway, thanks again for everyone's help, much appreciated.Leave a comment:

Re: Multimeter Settings
Alright, so I have just re-done the test as shown in the youtube video using the DV Volt 2V scale setting and got the following results:
Negative shows 0.056
Positive ranged from about 0.3 to 0.6
How does the 0.056 reading relate to voltage under the 2V setting. I guess I am just not too sure what the various settings mean. I am told that a loss of 0.5 volts or less is good, so is this actually 0.056 volts or does that decimal need to be moved?
I am also not sure that the test is working right on the positive...Leave a comment:

Re: Multimeter Settings
Yeah, I think my girlfriend actually filled the car up just a day or two before this happened, so I will likely be extracting some gas to make the removal a little more manageable. I am going to be heading back out soon to re-run this test using the proper multimeter setting and hopefully there is good results removing any doubt that it is the fuel pump.Leave a comment:

Re: Multimeter Settings
Ok, that makes sense. It is a 1997 Chevrolet Lumina. Are Honda's prone to these issues?Leave a comment:

Re: Multimeter Settings
I have also changed the fuel filter and pressure regulator. I figured I would change all the cheap quick things first. When you say hook the pump up to a good power source, do you mean while still in place, like directly to a battery?Leave a comment:

Re: Multimeter Settings
Perfect! Thank you so much. I have spent a lot of time today searching the internet trying to figure out what setting the multimeter should be in, but had no luck. And like you say in the video, he doesn't mention it, he just turns it on and I couldn't see what he put it to.
I will head back out tomorrow with the setting information and your very nice diagram and give it another shot. Hopefully the wiring is all good. I think changing the pump would be easier than chasing a bad wire problem. I have changed the fuses/relays because they were...Leave a comment:

Re: Multimeter Settings
Hi, thanks for the help. I think my terminology might be wrong when trying to describe what I am doing. The youtube video is here:

If you have the time to watch it, it will likely explain what I am trying to do better than I can.
I did try this procedure on the power wire but the meter was not looking at all like it did in the video or even like it did for the ground so I figured I would come inside and see if I could figure anything out through a forum. That is where...Leave a comment:

Multimeter Settings
Hi everyone. This site seems to be more towards computers and home electronics, but I think the same process would apply for what I am trying to do. I am trying to determine if the wiring to my car's fuel pump is good, I would hate to take the tank off to change it if it is an electrical problem. The car runs but only at 20 PSI fuel pressure, where it is supposed to be at 40 PSI.
I have read that it can be an issue of the pump not getting enough power to run as it was intended.
I have attached a picture of what my multimeter is set to for the voltage drop test, please... -
Re: New Members - please post your introductions here
Hi everyone, I am new here. My name is Adam. I found this site through a google search and it looks like this is just what I need. I am not very good with electronics and this will likely help me out a lot. Example being that I don't even know how to use a multimeter properly.
Anyway, looking forward to bouncing some ideas around here. I would like to be able to answer questions and help that way, but as stated above I don't think my limited knowledge will be of much help to anyone. Thanks.Leave a comment:
