So I have a 2000 TJ. I have replaced the crank position sensor and the camshaft position sensor. I have also replaced all fuses. The jeep would drive and die about 30minutes later and now after two months it has finally stopped turning over. The weird thing is, none of the gauges work now. I have little pressure at fuel rail so I bought a fuel pump. I will replace that soon but the weird thing is when I disconnected ground from battery and put back on the gauges worked and then I went to turn it over and they went back to not working.
