Bronco 2 wont start

[jthomasrichards]

88 bronco 2, 2.9 liter. Starts fine in the morning when cold, after that keeps cranking untill it fianlly comes to life. Almost kills the battery. Can any one point me in the right direction?

oxygen sensor i would replace it mine would run fine when i 1st start it. then run like crap after driving it for a bit and eventually stall and you couldnt get it started again and if you did it would just stall again. and it turned out to be the oxygen sensor.

Pull codes.
Test the TFI module

When it wont start, is it not getting spark or not getting fuel?
