My 1991 eb ford fairmont starts when i turn the key but stops as soon as i let the key go
Hello, It sounds like a bad Ignition switch. The keyswitch provides power to its terminals in back of the switch. The engine will have power to turn the starter and run the engine when the engine is in the START position. When the key returns to the RUN position, the next terminal on the switch is suppose to provide power to run the engine.
When the electrical contacts inside the switch wear out, the power is not put through the plug-in terminals. That is when you replace the Ignition switch.
To replace the Ignition switch, if it is in the steering column, you disconnect the negative battery cable first, and then remove the plastic cover on the steering column. There are screws under the bottom cover and you just remove them through the small holes moulded in the plastic cover. There may be a hole near the bottom of the Ignition switch which requires a long nail or drillbit to press a release spring.
Usually the key needs to be in the ACC or RUN position and the key core will pull out of the switch. Then you make a mark on the frame of the steering column before removing the switch. Some mounts are adjustable and some just bolt up and making a mark is not necessary.
Then reverse the removal procedure to reinstall a new part.
