Hi, I am having a problem with intermittent starting problems that the dealer can't find the cause of and no codes show up. I have a 2002 Sport Trac. Wondering if anyone has had same problem. It started after battery went dead and I changed it. I don't know if the battery had anything to do with it or not, but that was sequence of events. A day later I came home for 1/2 hour or so and when I tried to leave, the Trac would just crank but no start. I won't go into details of tow and all that, but when we took it off tow truck it started right up. Mechanic couldn't find any thing wrong. Few weeks later same thing happened, I let the car sit for an hour or so and it starts right up. Happened 2-3 more times same thing, crank good, no start. Dealer checked security system and did electrical system ground testing. Problem didn't happen while at shop so they couldn't fix it. Happened again a couple of weeks later. Any suggestions?
