CJ's MJ Posted February 12, 2015 Share Posted February 12, 2015 I finally have some time off from work. It's time to start working on my 89. It has a 4.0 in it. Since the first day I had it, it has been hard to start. It has always taken several attempts of long cranking to get it to fire up. Recently it has started to back fire before it wants to start. I am thinking maybe the CPS. I saw cruisers write up on things to do and plan on doing the entire list today to see if it improves. If anyone has any suggestions besides that please let me know. It's my first jeep so it's definitely a learning experience for me. Link to comment Share on other sites More sharing options...
xjrev10 Posted February 13, 2015 Share Posted February 13, 2015 Crank sensor Old plugs/wires/dizzy Bad gas Could be a number of things. Link to comment Share on other sites More sharing options...
