Why distributer drive gear lays done

Make sure trans has proper amount of fluid...

Have you retrained the gear? From memory think goes motor running foot firmly on brake park to neutral three times, neutral to reserve three times, neutral to drive three times, keep going thru all gears Then drive car normal for ten minutes minium as you usually would.

Sounds like you have a bad starter drive gear assembly (the gear on the starter that engages the flywheel gear). The drive gear has a one way clutch to prevent spinning the starter with the flywheel on engine start. When the clutch goes bad it does not spin the starter drive gear. If that's the case you can replace the starter drive rather than the whole starter, and you should also check the flywheel gear teeth to make sure none are broken or worn excessively.

the starter has nothing to do with it... taurus' are known for stripped out torque converters. most likely the case. about $1000 job

Low trans fluid? Check that first.

Sounds like your fuel pump is going bad. Have your mechanic do a pressure test on it.

I dont know why, but one time my truck was low on trans fluid and after I topped it off, it didnt stall anymore when put into gear. as fro the odometer i dont know, it may have to go out completely before any diagnosis can be done.
