left key in "on" position overnight, now no start

2.2 eco engine

thanks jim, checked fuses under hood, all good, was getting dark so checking spark tomorrow, much thanks PS: pricing ICM's now, in case ;)

good news is that the ICM is good, spark a'plenty there, seems that somebody, not I, had started car.....and walked away, ergo, run all night and eventually out of gas, guess why battery wasn't dead. Had a 1/2 tank of gas in it day before. Damn kids I'm betting ;) never bothered to look @ fuel gauge because I had just put 20$ in it day before. SO putting 2 + 2 together, key left in on, and gas now gone, plus battery still good, this Sherlock deduces it was some shenanigan's going on and NOT mechanical / electrical failure....Sorry to have bothered...lol

which fuses might blow if ignition switch left on while cj7 not running
