It goes off without warning acc start setting

The starter circuit goes through the gear sensor, and possibly other switches. If any are open, current doesn't make it to the starter. If Park doesn't work, try Neutral, as a test. If you can find a location for the shifter where it cranks, that would suggest the switch has come loose or shifted its position from where it should be.
Are there any starter noises, such as the click of the starter when you attempt to start? If a click or a chatter, the battery may be low.

Hello Ron, If your car does not crank when you turn the key, it sounds as if you have problems with the ignition switch . Or the actuating rod is disconnected.

NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with a scan tool.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.


Audible Warnings Warning Condition Lamp Duration Audible Duration Audible Output Safety Belt 60 Seconds 6 Seconds Chime, 60/Min. 740 Hz Key In Ignition - Continuous Chime, 120/Min. 740 Hz Headlamps On - Continuous Chime, 240/Min. 740 Hz Door Ajar Continuous 1 Second Single Tone, 1000 Hz Message Center (Tone Request) - 1 Second Single Tone, 1000 Hz
When the is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
The will turn on for 60 seconds or until the driver safety belt is fastened. Both the chime and the lamp turn on at the same time.
If the safety belt is buckled before the ignition switch is turned to RUN or START, from OFF or ACC, neither the chime nor lamp will be activated.
Anytime the is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed or the safety belt is buckled.
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open.
The key-in-ignition warning will sound when the driver side is opened with the key in the and the in OFF or ACC. It will continue to sound until the key is removed, the is closed, or the is in RUN or START.
The headlamp-on reminder chime will be activated if the headlamps or parking lamps are on, the key is not in the ignition switch, and the driver door is opened.
A single tone will be provided each time a ground signal is received from the message center. A one-second tone will sound for warning indications from the message center. A 100 milli-second tone will sound for each message center button depressed.

Driver Information Center (DIC) Equipped

Step 1 of 5

Place the key in the ignition and then turn it to the On/ACC position with the engine off.

Step 2 of 4

Step on the accelerator pedal fully to the floor three times within five seconds.

Step 3 of 4

Turn the ignition key to the off position.

Step 4 of 4

Start the engine to ensure the oil warning light is no longer illuminated on the instrument panel. If it is,repeat the procedure.

Acc means 2 clicks forward, without starting the vehicle

To disable this light without unplugging the battery:

2. Place odometer on Trip A
3. Turn car off
4. Place your finger and hold the odometer trip button
5. Turn key to the "on" position while holding the trip button; not "acc"

7. The maint reqd light will turn off

Hello, no you should not be able to turn it back and yes in accessory position it will have the alternator light comming on without engine running. Please rate this answer, thank you.

Warning Chime Systems The generic electronic module (GEM) will sound the following warnings:

• key-in-ignition warning
• safety belt warning
• headlamp switch ON warning
• door ajar warning

------------------------------------------------------------------------------------------------
Headlamp Switch On Warning The generic electronic module (GEM) sounds when the driver door is opened while the headlamp switch (11654) is in the PARK or HEAD position, and continues to sound at a rate of 4 chimes per second until the headlamp switch is turned off or the driver door is closed.

• When the headlamp switch is in the PARK or HEAD position, power is supplied through Circuit 293 (O/R) to the GEM.
• When the driver door is open, the driver door open warning lamp switch (10B997)is closed and ground is supplied to the generic electronic module (GEM).

A delayed headlamps on repetitive chime will sound for a period of three seconds beginning twenty seconds after the key is turned to OFF, LOCK or ACC, the headlamp switch is in the PARK or HEAD position, and the driver door is closed. Delayed headlamps on is terminated by opening and closing the driver door again.
---------------------------------------------------------------------------------------
Door/Liftgate Ajar Warning The door/liftgate ajar warning functions as follows:

• The generic electronic module (GEM) sounds a warning tone for one second when any vehicle door, liftgate window or the liftgate is ajar without any other door already open and the ignition switch is in the RUN position.
• Power is then supplied through Circuit 627 (BK/O) to the door ajar warning indicator lamp which remains illuminated until all doors are closed or the ignition switch is no longer in the RUN position.

----------------------------------------------------------------------------------------------
Key-in-Ignition Warning The generic electronic module (GEM) sounds when the LH front door is opened with the key in the ignition switch and continues to sound until the key is removed or the door is closed.

• When the key is in the ignition switch, the ignition key warning switch terminal and wire (11A128) is closed and ground is supplied through Circuit 158 (BK/PK) to the generic electronic module (GEM).
• When the LH front door is open, the LH front door open warning lamp switch (10B997) closes and ground is supplied through Circuit 57 (BK) to the generic electronic module (GEM).

-------------------------------------------------------------------------------------
Safety Belt Warning When the ignition switch is turned to RUN or START from the OFF or ACC position and remains in RUN or START, the chime will sound for six seconds or until the safety belt is buckled. The safety belt warning indicator lamp (10C859) will turn on for 60 seconds, or until the LH front safety belt is fastened. Both the chime and lamp activate at the same time. If the safety belt is buckled when the ignition key is turned to RUN or START from OFF or ACC, the lamp will prove out for two seconds, but chime will not be activated. Any time the key is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

The key switch usually breaks or wears out and makes contact. It is on the lock cylinder. This would cause the chime to not come on, or stay on. Sounds like the switch is bad.

1997 F-150/250 Warning Chime, Key-In-Ignition The key-in-ignition chime warns that the key is still in the ignition when the driver's door is ajar. The key-in-ignition warning chime will sound when:

• GEM: Driver door is ajar, the ignition switch is in the OFF/LOCK or ACC position and the keys are in the ignition.
• CTM: Driver door is ajar, the ignition switch is in the OFF/LOCK, ACC or RUN position and the keys are in the ignition.

The key-in-ignition warning chime will stop sounding when:

• Driver door is closed.
• Key is removed from the ignition.
• GEM: Ignition switch is switched to the RUN position.

The key-in-ignition warning chime inputs are:

• Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
• Ignition switch ACC position (battery potential on RUN/ACC input only).
• Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).
• LH door ajar switch (open circuit with door closed, grounded with door ajar).

This is a pic for a 98, could not find one for 97 which may be the older style which is more prone to break.

You should be able to reset the oil life light.
TRY this...
put the key in and turn to the accessory point,do not start the car.
Once you get to "acc" on the ignition press down 3 times on the gas pedal but NOT fast,sort of slowly.
Turn it off then start the car,it should reset and the light goes off if not..repeat it.
Always works for me.
I hate the reminder set up,stupid if ya ask me,i know when to change oil etc.
