Attached is a vacuum diagram from ourdatabase but seems the wordings are a little faded, don't tell me data in computer languages also fades over time? lol.

The difficult starting might not be a fuel pump problem. Have the fuel pressure checked. It could be a line leakage or a faulty fuel pressure regulator.

Is the Check Engine Lifgt indicating?

To replace the multifunction switch, you would have to remove the steering wheel, which would be easier if not equipped with air bags.

Being a carburetted version, there would be no CEL to show.

The carburettor is not functioning correctly due to vacuum leakages. Once this is rectified, the carb might work correctly.
