cranks but doesn't start
So I got this '96 Jeep Cherokee XJ that cranks but doesn't start. It's got around 180k on her but I keep everything in good shape. Batt seemed strong.
I used to drive it everyday but this past year I've driven it only about twice a week. It's been just slightly slower to start in the last couple of months, but just barely slower. Was guessing it had something to do with aging plugs or something.
Drove it yesterday and everything was normal like always, sat overnight and today it cranked but didn't catch.
Any ideas on where to start?
