about a month ago my 2002 sante fe 2.4 manual shut down unexpectedly. i was driving in town and the whole car just completly shut down on me and would not start tryed to roll over with no luck. i took it to my mechanic and he went through took him about a week and a half. he changed the crank sensor fuel pump cam sensor and the rapid misfire sensor all had been in properly installed before. but once he got it to start again i drove it for one day and it shut down again. called the mechanic we towed it to his shop and now im going on my fourth week of waiting and he still cant figure out why it wont get a spark he thinks and so do a few more mechanics that its a computer in it that is messed up does anyone have any ideals of what it may be so i dont end up spending a fortune on this car? any help would be appreciated. ive read somewhere that they can get moisture in the computer and shut them down anyone have any thoughts on that?

thanks for your time
