I have a 97 tj 4.0 that keeps losing fire. I have changed everything to do with fire all the way down to the ECM. This means wires plugs coil crank sensor cam sensor everything I know of and still it has no fire. When I changed the ECM it worked again for about a month and then one day would not fire and after about 10 minutes and a lot of steam :x I went to go start it and it fired right up! Then yesterday I went to go home after I drove it and no fire. My question is?? I changed the timing chain about 6 months ago and when I put it back together it ran like a lawn mower it was 180 out and instead of taking it all apart and moving the gears to the right position I reversed the wires from back to front and it fired up and ran great. Would this cause my problem?? And is there any way of seeing if my computer is bad? Such as some where I could take it and see if its ok?? I never had an issue until my timing chain jumped time and after this is when all has happened? I realize I need to change it to original and will do so but for me to know this is the problem I need it back running so when I do fix it back it will crank. Im just wondering if this could be causing my problem?
