My wife is supposed to be delivering flowers for out shop tomorrow, and the Big D is acting up. It seems to have left the radiator fan running, which killed the battery. I was busy wrapping roses for Wizard's wife at work, so I wasn't able to get home. My wife and mother (what a combo) attempted a jump start. They got it hooked up, and as soon as they did, the fan began to run. I had her pull out the fan relay, and the fan quit.
Upon attempting to crank, she reported that the engine cranked over strong, then fired, but died immediately. When I got home, there was enough juice in it to crank it over a couple of times. Sure enough, it would fire, but died right away. I tried a full-throttle crank, and it started, but as soon as I let it back to idle, it died. Slowly, I was able to let it down to 1500, 1250, 1000, 750... and then I took it around the block. At the first couple stops, it had a real "lumpy" idle, but then it smoothed out. After 5 min or so, it seemed to be running like normal. However, the engine light is on. I also re-installed the fan relay, and the fan does not run. I also installed a spare relay I keep in the truck for just such an occasion- didn't run on that one either. Of course, I doubt that the PCM is calling for the rad fan at 2*F.
So what causes the won't-idle after a jump condition? Is it just an extremely dead battery? I have the truck hooked up to an automatic charger overnight. Hopefully she'll be fine in the morning. Any tips? Things I need to check before sending her out for the day?
on edit: The first time I tried a full-throttle start, it coughed. The second time, it started.
