Over drive wont turn off

Hi do check gear linkages or cable adjustments.otherwise possible gearbox malfunction.

check the fuse-and the relay-there may be a similar rely that you can switch to see if it works- Denny

anti theft? bad starter?

is there a check engine light, possible mass air flow sensor

i have found many problems with electrical ignition switch to be the problem

SOUND LIKE ALTERNATOR NOT CHARGING BATTERY.CHECK BATTERY VOLTAGE SHOULD BE 12.6 VOLTS.MAY SURE BATTERY CABLES CLEAN AND TIGHT.WITH ENGINE RUNNING CHECK ALTERNATOR OUT PUT AT BATTERY.SHOULD BE 13.5 - 14.5 VOLTS WITH ENGINE RUNNING.IF ALTERNATOR FUSE GOOD AND ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES OKAY NOT DAMAGED.DRIVE BELT NOT SLIPPING OR BELT TENSIONER NOT DAMAGED.ALTERNATOR MORE LIKELY FAULTY.TURN OFF RADIO FIRST.BEFORE REMOVING NEGATIVE BATTERY CABLE TO KEEP FROM LOSING RADIO CODE.

Have the battery tested for a dead cell. It may test at 12 volts but that doesn't mean there isn't a dead cell. Also, if the motor has good compression you probably shouldn't be able to turn it over by hand at the fly wheel. Maybe an old school motor with V belt, but not a newer motor with all those accessories attached to the front.

It sounds like a loose ground, I would check all the fuses or see if this may be a short in the fuse box itself.

the alternator may of went bad and stopped charging so the car died when the battery went dead. Charge the battery and test to start with. Are you saying wont turn over ot turns over and wont start. If it turns over and wont start then it could be several things. Will need to get it diagnosed to be sure

Timing belt might have broke. Same thing happened to mine. Going to cost ALOT of money to fix.
