Hey guys first time posting here and lucky me has a fun problem to solve. So I have a 2000 TJ with 2.5 inch lift, 32's, 4.0/auto, subs & amp, and remote start. Truck has 90k on it now and it has just started acting up on me over the past week.
The problem is that sometimes it won't start. I will get in and nothing will happen. The starter will click and I can hear the fuel pump come on but no lights or anything will come one. After either holding it in the start position for 4-5 seconds or retrying to start it 4-5 times it will fire up but then runs rough at idle and then dies. It doesn't matter if I rev the engine up right after I start it or not it still will die when it comes back down to idle. After it acts up I can start it up and it will run fine. It doesn't do this every time and it doesn't do this in certain conditions. Here is the best part, it never ever throws a check engine light when it does any of this.
Looking to see if anyone has had anything like this happen to them or can give me a place to start looking. I have heard the TPS or CPS could be going but im not sure because its happening all the time. Looking for any help if anyone knows where to start or what it could be, I don't wanna just start throwing parts at it becuase that starts to add up pretty quickly. Thanks
