I have posted this before but have never been able to fix it. 2000 with 130K. Problem became worse progressively. It isn't getting worse anymore. When I bought my XJ with 80K miles it started instantly. I have done stuff before, but just replaced my Champion truck plugs. My last plugs probably only had 20K on them. Currently running another can of BG44K through the tank. I have never replaced any sensors.
My jeep cranks a long time now before it starts. I thought it was a bad check valve in my fuel pump. However, if I turn the key and wait for the fuel pump to pressurize, it doesn't seem to help. Still cranks a while. If I crank for a while, turn the key off, then on again it starts right then. My battery was weak and I just replaced it with a Odysee 1200. Was hoping for it to get better. No dice.
Once the engine starts it sputters along. After a minute or so it will go away. If I push the gas and get past the sputtering idle, it revs just fine. It is hard to get through this spot if I try to go right away. I sputter down the street a while. I get no CEL. This is only on cold starts. If I'm running around doing errands it starts just fine. This is annoying. I have almost forgot how nice it was when my XJ turned right over. Any other time my engine runs smooth and strong. No problems. Any help is most appriciated.
