A jumper wire with mini-alligator clips on each end is a ‘tool’ I have used since 1972. Low voltage and searching for ground with a DVM is a combo that has served me well.
A tremendous help. Your "quick diagnosis check" tip enabled me to get my repair parts shipped to me in 2 days. I was able to place the order early in the day and not have to wrestle the gas tank out of the jeep and then try to decide if the gauge was bad. Thank you very much for this video, it saved my day! (Wow, don't we wish we had been access You Tube in the old days. Old mechanic Bob would not have told us.)
Awesome video. I know this question does not pertain to this video, but you seem to show the best DIY for Jeeps. I wish you would do a video on how to completely R&R both the side windows with weather-strips and the rear lift window with weather-strip. I am planning on repainting my 1991 Jeep YJ hardtop and want it to look OEM. Thanks a bunch for all your great videos.
Great suggestion! The side window I can do. The rear hatch, my YJ top is missing all that lower mechanism and trim at the bottom of the rear hatch. I have a CJ top that has it and I will be restoring it soon. They are very similar.
Thanks for the video. Have a 91 4.0 The PO ripped out the factory gauges. He cut the plug to the instrument cluster out completely and installed cheap aftermarkets, minus the fuel gauge. I'm trying to locate the wires to the fuel sender with no luck. Would you happen to know the color coding for the fuel gauge wire behind the dash? Thanks!
I did the jumper test at the plug, gauge moved from empty to full. What are my chances of having a bad ground connection? Would the pump still work with a bad ground? It runs fine but want my gauge back.
It could be Tank float is hung up on the tank float cradle inside the tank. The plastic cradle warps over time and restricts the float lever movement so it gets stuck at half tank or empty Also I have a 2001 tj my friends/famliy freak out when the gas light is on. my tank is usually half filled most of the time. sometimes I mess with them and say oh no we could run outta gas in the middle of nowhere. I don't have any cash for gas do you? Sometimes I say we will be fine I have half a tank they look at me like I'm crazy I say any of the following in any combination. relax live dangerous. 🤣 don't be Ina such a hurry. have no fear. Face your fear.if we get stuck I have roadside service.i use to freak out on the trail my tank would be at half then blamo on E I'd and be like wtf? 🤣 I never worry about it now. if you are trail riding or off roading you should bring at least a five gallon spare tank though fill it before your trip then rotate it in between fill ups if you don't use it on your trip off raoding so you have fresh fuel it's good to have extra fuel on hand to help someone stranded on or off road especially the newbs.
Thanks for your videos I think I saved all of them but my question is when you touch the wires to the connector is both of the ends of the wires or one touching both ends
Love the video. My fuel gauge is always showing full. The fuel sending checked out ok. I attempted to jump the two pins in the connector as in your video, but the fuel gauge won’t move. The gauge itself checked out ok in the dash (I can jumper the gauge to ground) and it moves. I must have a problem in the wiring between the dash and the fuel tank. Where is the body harness connector “left of the steering column” / “above the park break release lever” located? I believe I have an open fuel level sensor wire in the harness somewhere. The fuel pump runs (I have power and ground) Any guidance is appreciated.
so i bought a new sending unit and pump. installed it. my gauge is new as of a few years ago. when i put the new unit in and turned it on the gauge went from E to full.
Have any advice on a dead gauge cluster? I’ve tried a different one. Different pcm. Tried messing with the pig tails to gauge cluster. Cleaned everything. Checked every fuse. Cluster lights up. No gauge movement. Open circuit panel. Bus 60, 68.
Hey Chuck... Great vid again. Are you gonna do the lifters video, cause I hear it is different changing them on the straight 6 compared to the 4. I think it would help a lot of people out wanting to change lifters to get rid of that tap that comes from lifters that is very common.
Hey Daryl! As Kim Kevan said, I did a video on changing the rockers, push rods and followers a while back. I did the video on a 4.0 TJ but its the same procedure on a YJ. I've driven and and ridden in that TJ several times since doing that video. Not only is it quieter, the performance is surprisingly SO much better. I really didn't expect that at all!
Hey quick question, how many volts are coming back to the fuel gauge? I'm installing a GPS that can read fuel levels but is 0-5 volts if 12 are coming back I could get a resistor and drop the ohms by half.
My buddys 1995 wrangler almost melted thru the gas tank because the plate holding the tank rotted in half. The plastic tank fell onto the exhaust and melted a hole thru it. He noticed a drip in his driveway and then seen the damage. Had he went for another ride without noticing ,,he may be dead now. I have same jeep as his. 1995 YJ wrangler. I replaced my sending unit and pump a year ago and now when my tank is full it reads 3/4 full. I think I put a 20 gallon gauge into a 15 gallon tank. And we are trying to figure out what tank he has now so he dont do the same thing.
My problems are, jeep (93 YJ), is hard to start, if not ran daily. Runs out of gas, with several gallons still in tank. The gas gage, reads full when empty, and reads empty when full. Any ideas? Thanks.
The problem with my gas tank is it when it reads three-quarters emptyit is empty and then it looks like I still have a quarter of a tank of gas and I can't tell what should I do take down a tank clean everything
Its that little internal plastic bowl/basket thing. Over the years it warps causing the fuel float hangs on it not allowing the float to go to "Empty" position. Therefore making the gauge read 1/4 tank when it fact it is empty. Snatch that bowl out and your good!
Power Addicts - FixJeeps.com - Jeep, car and motorcycle tips Chuck, which side of the jeep are you on? How do I locate the wire and coupler if I don’t have a body lift? Your videos are awesome!
The body is the least of your weight. Most of your "high centered" weight is frame and engine. Having a body lift doesn't really make them top-heavy. Suspension lift or SOA makes the rigs top-heavy because you are picking up frame, engine, and body. The main drawback to 3" BLs is the stress it puts on the body mounting points and generally looks bad with that massive gap. Good to see ya hanging out on the channel!! Have a great day!!
The float could be hung up in or on the float cradle in the tank you could just cut away the section the float gets hung up on the cradle or rip the cradle out completely the cradle warps over time or get a new tank and sender the cradles are junk plastic. sometimes they break in the tank causing a misalignment and the float gets hung up on the cradle if the tank is trashed I'd get an new aluminum or stainless tank with larger fuel capacity or a tank and sender out of newer jeep just my 2 cents
Hey whats up?! Good to see ya still hanging in with the channel! I've never personally tried it or know anyone that has. From what I've seen in forums and FB groups you need the bell housing from a Dakota or Ram that has the 3.9 5-speed. I do not know if this is true or not so you can google it and search the forums for the information. Have a good day!!
Hey power addicts, have a question for ya!? I actually put a new aftermarket fuel gauge in and when I turn my jeep on it goes way past the full position to the 30 position (thinking as if it were a clock) and got stuck there. After disconnecting the harness wire from the gas tank, I sprayed some electronic cleaner and lubed it up and now it goes from the 30 position to about the 25 position. Do you think this is an electric issue or an actually fuel gauge issue? My stock fuel gauge which ofc I don't have anymore, would either be stuck on full or wander around like a lost child in a mall. Any suggestions would be much appreciated!
Its an electrical issue of some form .. .meaning .... its either a wire shorting issue or the wrong resistance. Your sending unit must match the Ohm (resistance range) of your gauge. If the resistance range doesn't match the gauge will not read correctly.

Sometimes the most simple of tools can help diagnose some of the most difficult problems! Thanks for leaving an awesome comment! Have a great day!!
Thank you. Finally someone made this simple.
Ive got another video the goes way more indepth. Its not as simple or as short as this video. Here ya go: th-cam.com/video/6i9X2agOEYs/w-d-xo.html

Another great video from a fellow Jeeper and bike rider! Thanks for all you do!
You are welcome fellow Jeeper and biker!! ✌
Thank you this was very helpful found the pin in the connector broken that was the whole problem. 🙂
Awesome videos as always. Always top notch and very helpful for sure. Another shop bill avoided.. Thanks a million AGAIN..
Every video is so good I want to hit subscribe again even though I've been subscribed for a long time!

I did the jumper test at the plug, gauge moved from empty to full. What are my chances of having a bad ground connection? Would the pump still work with a bad ground? It runs fine but want my gauge back.
mine is the same. pump runs fine but gauge shows nearly full all the time. im thinking ive lost ground between molex plug and dash ground.
I'm having the same issue. Gauge reads E. Fuel pump has been working great.
It could be Tank float is hung up on the tank float cradle inside the tank.

@@mariotibbrine1 yeah I removed that piece in the tank. Since I posted this I replaced my fuel pump and all good now=bad sending unit
@@jeeperguy4290 was the sending unit float arm flopping around wore out the pivot point?
Thanks for sharing!
Thanks for watching!
Thanks for your videos I think I saved all of them but my question is when you touch the wires to the connector is both of the ends of the wires or one touching both ends
Does this work with the 87- 90 with the weird older style wiring?
Great video! I have a 97 Wrangler and replaced the PCM, after that the fuel gauge stopped working. Any ideas?

Hello i want to say really good video. But where can I find that wiring diagram at?
so i bought a new sending unit and pump. installed it. my gauge is new as of a few years ago. when i put the new unit in and turned it on the gauge went from E to full.

What actual wires are you using to test you never really specified
Where did you get that top? Need one like that for my 93!
Morris 4x4. Its a Rampage Cab top. Just a heads up, You got to have the factory original YJ soft top frame. Thanks for hanging out!
The problem with my gas tank is it when it reads three-quarters emptyit is empty and then it looks like I still have a quarter of a tank of gas and I can't tell what should I do take down a tank clean everything

@@Poweraddicts what is the purpose of that bucket? My Jeep is having this same issue.
On my 91 YJ, the connector for the sending unit in inaccessible without dropping the tank
With no body lift there is very little room to access the wiring harness.
@@Poweraddicts yeah, like zero
Can I use any piece of wire? Are you just making a connection between the two pins?
You could. For back probing paperclips are easier to use.
How do I check if the sending unit is grounded correctly?
It your sending unit wasn't grounded correctly, the pump wouldn't work. They share the same ground.
Assuming this applys to a 91 xj as well?
Im not sure if the wiring color code is the same. Otherwise yes it should still work,
I’m having problems with my temp gauge in my 94 I’ve replaced all the basics any ideas past that or did you cover that in previous video?
Yep, did that video not long ago. Just pull the wire off the sending unit and ground it out. The gauge should hop on over to the other side 😀
Power Addicts - FixJeeps.com - Jeep, car and motorcycle tips Chuck, which side of the jeep are you on? How do I locate the wire and coupler if I don’t have a body lift? Your videos are awesome!
I got a 89, the plug is flipped and the gauge only moves when it’s primed, can anyone help
I dislike body lifts on jeep because they're already top heavy. A body lift makes them very prone to rolling over.
The body is the least of your weight. Most of your "high centered" weight is frame and engine. Having a body lift doesn't really make them top-heavy. Suspension lift or SOA makes the rigs top-heavy because you are picking up frame, engine, and body. The main drawback to 3" BLs is the stress it puts on the body mounting points and generally looks bad with that massive gap. Good to see ya hanging out on the channel!! Have a great day!!
I concur.
What is the problem when you disconnect the plug and nothing moves
I have changed just about everything dealing with my fuel gauge and it’s still not working. New fuel gauge,filter and pump
Then you could have on of the following issues: wiring, bad ground, or a bad sending unit.
The sending unit is new I think it’s some type of wire problem
The float could be hung up in or on the float cradle in the tank you could just cut away the section the float gets hung up on the cradle or rip the cradle out completely the cradle warps over time or get a new tank and sender the cradles are junk plastic. sometimes they break in the tank causing a misalignment and the float gets hung up on the cradle if the tank is trashed I'd get an new aluminum or stainless tank with larger fuel capacity or a tank and sender out of newer jeep just my 2 cents
Hey chuck got a question couldn't find your email but will the 318 bolt up to the 5 speed in my 95yj?
Hey whats up?! Good to see ya still hanging in with the channel! I've never personally tried it or know anyone that has.

Its an electrical issue of some form .. .meaning .... its either a wire shorting issue or the wrong resistance. Your sending unit must match the Ohm (resistance range) of your gauge. If the resistance range doesn't match the gauge will not read correctly.
My gauge doesn’t even go down to halfway when I do this. Is my gauge bad? It’s an 89.
Bad gauge or a wiring issue from the rear to the gauge.
What part of Tennessee are you from?
About 35 miles North of Nashville. Not far from the Kentucky line.

Mine just bounces around on my yj
Probably a bad ground or sending unit acting up
