Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

yes thank you we had a wire for the drivers windows that that was into that I spliced back together that fixed nothing to are covering anything else on the Jeep will crank over but the gas gauges and the old age isn't showing what it is and it's um it's almost like it's like not getting fire fuel but the night before it was perfectly fine and we had it for a while and it's like I said its a 2001 and the security system I think it's not letting it start but I don't have a keyless entry to it I just have the key but it was it was fine the night before

Hello and welcome to just answer. Your PCM has failed it is not a security system problem. The PCM (engine computer ) is not allowing spark or fuel and is also preventing the gauges from working. If find no blown fuses. Then have the PCM replaced. I have seen this exact same thing before and am 99% sure that this will fix it.

I hope that this information is helpful and please let me know if you need further assistance.

I would definitely recommend people to go here first before the shop I kinda thght it might be that but not sure daughter jumped jeep think she might of done backwards not sure and shorted it out I had driver door opened for wire and window wire broke I butt connected them back then put battery on charge after she tried to jump it and wouldn't start up like not getting fuel I thght maybe bcm or pcm going to junk yard today thku
Jeep Mechanic: Chris, Shop Foreman replied 2 years ago

Hmmm, jump starting it backwards could be the reason. That can kill controllers immediately. Let me know how it goes.
