ANY 05 JEEP G.CHEROKEE MECHANICS

Did it work?
At that time yes that was in Dec of last year but only lasted for a month then back to not starting In the mean time it wouldnt start without jumping it. I was told on line that the fuel pump wasnt getting enough volts due to a weak battery. I replaced the battery & alternator in Dec. Its been good ever since until yesterday. Its back to not starting again. Like i said its random. Could the relay gone bad ? I got the cheapest one they had at NAPA
