When I turn the key the Jeep does not crank. When I crawl under and use a screwdriver across the posts I can get it to start so I assume power is going to the starter.
I have not looked at the relay
Good ideas on bending the tabs a bit and cleaning up the contacts along with the grease.
I know i watched a video a couple years back when I replaced my fuel pump that showed someone taking apart the fuse block where the relay is located to get to the backside of it but for the life of me I cant find it now…….
Thanks,
So in essence if I was to remove the relay while the truck was running the truck should die out as the fuel pump would loose power (control side)
So now I need to find this fuse block center and replace it.
Yes,
I installed new brake caliper pins (slides) and all the noise went away. I was using the old ones with the new pads and had the clicking. After I changed out the pins the noise went away.
Success!!
Just took a couple times to get pressure back and air out of lines as I put new filter in also.
New fuel pump was not working out of box (even when I jumped it)
The next new pump worked when I jumped it but would not run due to the new relay that I put in. When back to my old relay and she runs like a champ!!
Getting closer but still scratching my head.
Double checked all the terminals at the fuel relay and everything came out like its supposed to from what I have read online.
I then jumped pins 87 to 30 and turned the key on and the fuel pump runs. :ohmy:
I took my new fuel relay out and put my old one in. Turned the key and the fuel pump runs for 3 to 4 seconds like it supposed to !!
Now the truck starts but only runs for short bit then dies…….
Of course it starts raining out so I’m on hold to look further………..
I am lost 🙁
Tried a different fuel pump and the same thing the pump is not running at all giving me no fuel pressure. Turn the key and I have 12 volts at the plug (gray wire) for the 3 seconds like its supposed to have but the pump does not fire up.
Well now that the 6 inches of snow has melted I am back under this thing.
At this point I am thinking this new fuel pump is bad. Now that I know what wires does what I have been able to check it better. I have power at the plug going into the fuel pump (gray wire) for 3 to 4 seconds like its supposed to work. I checked he ground and that lights up the test light fine.
I took a meter to the gray wire when I turn the key on I get just under 12 volts. The pump does not run, I have 12 volts at the gray wire at the pump and the ground is good. I have to believe this new pump isn’t working? I find it hard to believe but if I have power there it should power up for those 3 to 4 seconds………
Thanks,
I checked the fuse earlier a couple times, and the relay was clicking when the key was turning. Going to start around that area with test light and multi meter and see where my power is lost.
Thats huge, Thanks!!
Now I know what the wires go to so I will have to start my way to the front and see where the power is lost. Knowing what color wires do what is a huge help.
Will have to give it a couple days as we are getting snow tomorrow and its sitting in the driveway.
I have a cheap Multi-meter and to be honest am learning how to use it.
Using a wire directly off the battery I am getting 11.5 volts on the gauge and that is using the positive probe on the wire and the negative prob on the ground. I then take the positive probe and put it in the connector and then turn the key on and I am getting 8.6. Going to my fuel pump website it says fuel pumps typically draw between 6-10 amps and the relay minimizes the current flowing through so the pump doesn’t get burned out. So I am not sure if the voltage difference is OK but it sounds like it will not read the same? I am trying to figure out the voltage drop test but everything I read online says the pump needs to be running and it does not power up.
I am still wondering why the pump would not run when I ran a power wire directly off the battery to the pump.
Thanks for the replies.
I ran a wire directly from my battery to the fuel pump and touched the wire to the center pole going to the fuel pump and it does not power up. I’m assuming its the center wire that should be power as that is the one that lights up coming from the truck when I turn the key on. I really would like to make sure this new pump even works and I thought this should power it up.
I used a test light to check ground. I used the same wire coming off the battery, hooked the clip to the positive and touched the probe to the ground and it lights up showing me I have a good ground.
I cleaned the new rotors off with brake cleaner before they where installed.
I am going to take everything apart again tomorrow after work and see if anything is rubbing anywhere and look at the shield. It really sounds like the pads moving around but I don’t see how the way they are in there. Going to take a good look again and see if I missed anything.
Going to test it again also but I feel no pull in the wheel or vibrations.

Sure can,
The noise was not there before the brake job.
I put new rotor and pads on and it showed up.
I then put new caliper on along with the new pad and rotor and its still there.
I noticed when I brake hard the click is louder than if I just brake normal.
No noise unless brakes are applied.
I did not put new caliper bolts in that is the only thing not new. They are tight though along with the lugs.
