there is a fuel pump relay in all of them. The owners manual should have the location. It could very well be bad. There is also a fuse. Do change your fuel filter as well and if needed, check fuel pressure regulator on fuel rail.

Hot catalytic converters indicate too much fuel in the exhaust. This can be caused by poor ignition/misfiring, a problem with fuel/air ratio, ignition timing, cam to crank timing(timing belt/chain).
Catalytic converters have the capability to break down excess hydrocarbons by process of chemical reaction. The more fuel, the more heat. The problem is that they will eventually melt and plug up. So I suggest you repair soon.

insturment clusters on these cars are known for going bad and blinking on and off. get the cluster fixed or get a used one. there is a company on ebay that will fix it for around $75.00, with a lifetime warrenty. just go to ebay and type in 93-94 lexus ls400 insturment cluster. There ad will come up and just follow the directions. Trust me this will fix the problem. It is also cheaper than buying another one that has no guarantee.

there is no repair, you can try to clean but thats it,gotta replace it.

yes its possible it has a factory immobiliser ,from around 94 but as its a take off of a merc then yes its highly possible it has alarm ....sorry if it has dealer only
