1989 F150 ignition cylinder switch

When starting my F150, the cylinder switch goes from the start position and on the return to the run position it shuts off. I have replaced the cylinder switch with the same results. The key is in the run position but the engine turns off. I can start it very carefully, and manually movr the key to where the motor still runs. But the least little movement of the key and the engine shut off.

Remove the ignition switch cylinder and inspect the contacts in the column. Look for dark spots, scratches, excessive scuffing. My guess is that cleaning the contacts with a little tiny piece of sandpaper and perhaps bending them out a little (so there is more pressure between the contacts when you reinstall the cyclinder) will cure the problem.

1989 ford f250 wont run with key in run position but will run while cranking


You would need to know if the coil has voltage when the key is in the on position.
The problem could be the ignition module, or the circuit back to the key switch. If the EEC relay is not working, you could have power for the coil in start coming from the starter relay-solenoid but not in run from the key switch.

Problem with starting 89 F150 straight drive. Ignition or clutch?


Sit up on the clutch paddle, follow the clutch paddle up under the dash, the rod that goes through the fire wall to the clutch master cylinder, sit around that rod, will have a six pin connector going to it.

Ford f150 the windows,radio & wipers don't work when the motor is runing then i turn it off & place the key in the back position of the switch they work


Might want to remove the tumbler, and check it for obstructions, or dirt in the grease.

One quick test for this would be :

Start the truck as normal. Check the radio, if it is off, slightly turn the key backwards towards the off position, only moving the key 1 or 2 mm. It could be the key is not returning from the start position correctly.

To check the tumbler :
Look on the bottom of the steering wheel cover. There should be 4 holes, but only 3 screws. The empty hole should be by the ignition switch.

1 Insert the ignition key and turn to the RUN position.

2 Insert a punch in the access hole of the steering column and press the release tab while pulling out the ignition switch lock cylinder.

Once you have it out, you should be able to look inside the tumbler path, to see if there are any obstructions, or grease & dirt build up.
This is also the same way to remove the key in ignition warning chime. It should be a tab on the end of the tumbler ( mine was broken, left in the tumbler path )
Pry the clip down, and push the tab off the rear of the ignition switch lock.

Putting it back is a case of pushing the same punch in the hole, insert the switch lock cylinder back in, release the punch, and cycle the key to the off position.

the ignition switch is an electrical part. The lock cylinder is whre the key goes and it activates the ignition switch. If you pulled the lock cylinder out, you could operate the car with a screwdriver.
Either you have damaged the ignition switch where the lock cylinder goes into it, or the lock cylinder is damaged where it fits into the ignition switch.

Section 11-05: Steering Column Switches 1996 Taurus, Sable Workshop Manual
DESCRIPTION AND OPERATION Ignition Switch The ignition switch (11572), which is mounted on the steering actuator housing (3F723), operates in the following manner:
  • The ignition switch is cycled through rotation of the ignition switch lock cylinder (11582) through a pin which is part of the ignition switch.
  • The ignition switch lock cylinder also controls the mechanism which provides a positive lock for the transaxle linkage and the steering system.
  • The locking mechanism is located in the steering column housing.
The ignition switch lock cylinder positions are:
  • ACC
  • LOCK
  • OFF
  • RUN
  • START
The key can be removed from the ignition switch lock cylinder with the column-shift transaxle only when the shift lever is in PARK position and the key is in LOCK position.
  • The ACC position operates while the steering and transaxle remain locked.
  • The engine shuts off when the key is turned to the OFF position without locking the steering or transaxle.
Blade Type
The ignition switch has blade-type terminals that engage with one multiple connector. The multiple connector is secured to the ignition switch by an integral connector fastener.
