Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello, my name is ***** ***** I will assist you today. Tell me: when you turn on the ignition to the "on" position, can you hear the soft whirring sound of the fuel pump come on in the fuel tank for about 2 seconds and then turn off? When you crank the engine, does the tachometer needle move up a little bit? and finally, does the fuel gauge and voltmeter come up when you turn on the ignition?
Ok, well then it sounds like the PCM ( engine computer ) may have failed. Do you work on your own vehicle or have a shop do that?
