Ignition lock

Lina:
The security light indicates a problem in the system. Was it the switch each time because that is really odd?

Mmm dont know about that, sounds a little shady, I would first have someone verify if there is fuel and spark. I will send you the info to show you how. If this has an alarm /immobilizer then that new lock may be a problem, and you say your gettin absolutely no sound when trying to start?

Symptoms indicates a likely electrical fault but is not going to be easy to diagnose as it restarts within a short time which makes it almost impossible to loated the cause before it restarts.

There are 2 different symptoms which might help to localise the problem but they might be too insignificant if you were not paying any attantion.

Did the engine cut off immediately or was there any notion of a slight slurge as if the the engine is starving of fuel?

Immediate cutting off would mean electrical controls whilst the other would be a fuel supply problem.

A failing fuel pump would test good but can stop intermittently and start working again.

Were you able to get any trouble codes?

I checked through the TSB and found one that might be worth a look. It states that the intank fuel strainer could be clogged and a new strainer kit is available.

When the strainer gets clogged, fuel would be prevented from getting to the engine and this would result in stalling which would result in no response from the throttle.

Intermittent faults are never easy to detect and if there are trouble codes, which would show on a scan tool, it would help to localise the problem.

It depends on exactly what you are doing. When replacing the ignition lock, they are shipped with no key coding and have to be assembled a d key coded.

Perform the following procedure to remove the ignition lock cylinder from the ignition switch:
Depress and hold the ignition lock cylinder detent.
Turn the key to the ON/RUN position.
Pull the ignition lock cylinder out with the key.
NOTE
Remove the ignition lock cylinder before you remove the Passlock- electrical connector.

Disconnect the Passlock- electrical connector from the ignition switch.
Disconnect the electrical connectors from the ignition switch.
Remove the ignition switch through the I/P cluster opening.
If the lock cylinder does not rotate or is seized, perform the following procedure:
Protect the immediate work area with suitable material such as clean shop towels or a clean fender cover.
Locate the surface for the ignition switch lock cylinder release button (2) on the plastic ignition switch housing and center punch a location (1) on the rib 9.5 mm (3/8 in) rearward, toward the key entry end, from the cylinder release button.
Carefully drill a pilot hole through the plastic housing with an 1/8-inch drill bit.
Carefully drill a larger hole at the pilot location, and slightly into the ignition switch lock cylinder surface to break the release button retaining spring using a 9/32-inch drill bit.
