I have an older Jeep that has been sitting a lot. I started it yesterday after about a month, it started up so-so, then once warmed up seemed to run fine. I took it on an errand and when I tried to start it up again, it was dead. The accessories worked, but engine did not turn over…after trying for about 10 min, I called a tow truck. An hour later the Jeep was dropped off at home, I tried again, and suddenly it started just fine. 1st try.
This morning after a cold night, I went out to try it…again, started right up. I let it warm up for a bit, then took it for about a 1/2 hour drive, even on freeway for about 10 min.
When I got home, I turned it off…after a min I decided to try again, and this time, NOTHING. Dead. Same symptoms as first time.
Could this simply be just a battery issue?
Catalytic converter does need to be replaced.
Battery is definitely old (7-8 years), it did sit a lot over last few years.
Transmission was replaced about 3 months ago.
I appreciate any help / suggestions.
