Check your power steering fluid.

Try testing the blower motor, usually located in the passenger side's footwell, under the glovebox.

Have you actually tested the other cylinder plugs to make sure they are definitely not firing? Not sure I know what you mean by the "firing box", you mean the ignition pack, coil pack, distributor or? If its a sealed pack it should be fairly well sealed to keep water out. However if you think the problem is that water go in there, spray it liberally with WD40. It will displace the water and it should start working properly, if that was the cause. Alternately you could try heating it up with a hairdryer set to max and see if that does the trick. Before doing all this confirm that the other plugs are indeed not firing.

is there a dist first or a coil pack are all the plugs good and do they have spark on each when you say it fires on 2 cyls which ones and do you have a check engine on you can check the codes and it should help you but if you have a dist you also have a rotor as well by removing the cap you should see corrosion under where the rotor hits on as well you have a pickup coil but dont go so far check plugs first for ware then go from there wires, coils, etc

Check the starting circuit fuses. Most likely its a bad starter. If you can easily get at it. Drop it out attach a ground line between the body of the starter and any clean metal under the car.

It is higher than you would expect and black like everything else under the there so do not give up (I almost did) it's there. Hope this helps.

If # 3 cylinder has spark at the plug it must fire if the following conditions apply. Injector is supplying fuel to the cylinder. and cylinder compression tests OK . So check above ,one or both must be at fault.

week injector

you don`t say how you verified that the plug and wire was good. I think these use coil on plug, if so check powers and grounds for that coil as one may have a problem.other things that could cause this is a bad fuel injector, poor compression due to either rings, valve, worn cam, damaged push rod,

If is just the lights, not the needles, it means the light bulbs are burned out. you need to take the whole thing out and exchange them. It should be 4-6 screws

First check the linkage Then loosen or disconnect to linkage, so you can shift the trans by hand If it has a cable involved, remove the trans end My guess is-- you need to pull the trans & take it apart to find the worn parts & problem Also the clutch may be an issue

What is the lubricating oil level?

if it is digital. under the hood in the main fuse box. if it is mechanical , check your connection at the transmission.

Yes. A loose battery clamp or side screw will prevent your battery from charging, also will affect exterior lights, and possibly cause other issues. Your terminals should be clean and greased with dielectric grease your battery should be clamped or strapped down.
