91 Jeep Cherokee Laredo fuel pump not working?
I just replaced the pump-and it worked for two days-I thought it was faulty so I put a new one in again and still no power to the pump. The relay is not bad because I exchanged it with other relays that are working and it still does not work. Does anyone know how to trace the wiring back or what to use to test to see if power is getting to the wires??? I have replaced the fuel filter and the screen that filters before the pump. There is no power going to the filter because there is a clear line at least to the fuel filter and when i disconnect the line, there is no resulting fuel in the line-thus it is not pressurized at all. No pressure is getting to the pressure release valve under the hood-I just don't know how to use a multimeter and what the readings need to be...

use a multi meter.

Your Jeep has electronic fuel injection. The pump will not run all the time. You need to have a fuel pressure tester to check the pressure at the fuel rail. You could have a clogged fuel line which would cause the pump to pressurize the system, then turn off. A tester would indicate this possibility. Have you changed the fuel filter? You have a steel fuel tank, could it have a lot of rust in it and getting caught up in the pump?

1999 jeep grand cherokee laredo after market stereo wont work?
okay so im replacing the stock stereo with a kenwood KDC-MP442U , i got the correct wiring harness's and used the correct wire connectors and everything, but when everything is hooked up and i go to turn my car on, the head unit doesnt turn on, but when i take the 2 red power wires and put a yellow memory wire, the deck turns on, but it stays on when the car is off. all of the wires are correctly matched up, and crimped down and connected properly when i had this deck in my 1996 jeep cherokee sport it worked normally what am i doing wrong, why is this deck not functioning correctly?

not working because you didn't connect the blue wire, you need to use that wire for the infinity amplifier, that is the remote turn on wire i believe it is white or brown it will be the only wire lose besides the ilumintaion good luck

You have a fuse that is blown not the amp turning on.. There are 2 power wires for a radio one is yellow and that gets power directly from the battery and the other is the red which only gets power from the key switch so it only gets power when the car is on. There is a fuse panel in the drivers kick it might not say radio it might be connected to a Cig lighter or dome light.. but if you change that you'll solve your problem
