2002 Ford Windstar Repair Question
Mileage: 130,000 miles.
Engine won't crank and battery drains quick when turning ignition.
Answer
When attempting to start I had full power but engine would not crank-Do you mean it cranks over and will not start or just won't crank at all/nothing when key is turn to cranking position?
It will not crank over at all. The computer clears all systems like normal when turning the key to the on position but the engine does nothing. As long as I keep the charger on, it will keep a full charge. When I take it off it drains at a moderate speed unless I attempt to crank it, then it drains quick from 12+ volts to 8-9 volts. I did a check of polarity on the ignition wire to the starter and it indicates no power. I am just came in from tracing the starter wire up to a connector which I believes goes to the fuse box or electronic ignition switch or both.
If there's no power on the start control circuit to the starter motor-check and test the starter motor, starter relay,transmission range sensor, and ignition switch-
