Question Left key on overnight and now idles rough, no power.

I accidentally left the ignition key on overnight and now my truck starts hard, idles rough, and has no power. The truck is 97 F350 7.3D Manual tranny with 250,000 miles. I tried disconnecting the battery for a few hours to reset the computer, but that didn't help. Check fuses, they are ok. Any suggestions on what part(s) may have burned up by having the key left on?

Key left in RUN, cold engine, the glow plugs will still only run for the first two minutes or so. Did you happen to look-see (or feel-see) how hot the PCM and/or IDM were when you went out and discovered the sitch?

Batteries would be low, requiring extra current from the alternator, lowering the voltage for a while; dunno if that would affect the power, though (maybe lowering the injector voltage?). Did you try throwing the batteries on a slow charge?
