If its the VQ 3.0 V6 then the ignition timing is done through the ECU via timing sensors. Here is a web site that has workshop manuals you can download for free. I have downloaded them for my 97 Nissan Maxima. https://manuals.co/workshop/nissan/maxima

If oil pump went out it would have blown up by now, it sounds like a lifter tapping. I would add a quart of Lucas oil.

Here is a link to a factory repair manual for model year 94, it is the same car as fact as mechanical go and electrical systems, look up the wiring and find the common power source for the things that don't work.. You will need a RAR file extractor tool, you can download one free on the internet. http://diyservicemanuals.com/nissan-maxima-service-repair-manuals

There is only one circuit. You have to trace the wire from the fuse to find the short. The wire runs to all of the parking and tail lamps as well as the instrument panel, thru the dimmer. If you find connectors along the way, disconnect them to find out if the short is beyond or behind the connector, using an ohmmeter.

Start at the battery. First make sure it has a full charge. Do not proceed until you know the battery is good and fully charged. Use a voltmeter to see if charged, or take it to a parts store for testing-it is a free service, and tells if your battery is good and can hold a charge. Next thing is to check your battery cables. Are the connections clean and tight, both at the battery and where the other end connects? Make sure no corrosion is on the terminals-that will rob power and may not let the battery charge up or put out power. After the battery and the cables are checked, now you should get power to the fuse block, do your headlights work now? Follow the power path-from the battery to the fuse block. Check all your fuses under the e hood, you may have a blown fuse.

Check all the connections on the ECM especially the ground wires. When the vehicle is put into gear, the ECM starts looking for the sensors, if the ground is bad, the ECM pulls ground current through the sensors. Then check the sensors.

Check the fule pump fuse and relay

Give yourself extra time to get to work. Then start your car and allow it to sit for 5 minutes to make sure that the engine is ready to work. This means that it is warmed up, everything has been lubricated. What light is it? You didn't say, and every light is labeled, so can you enlighten, (pun intended), me? You might be able to look it up on YouTube, never know. Good luck. 1993 Nissan Maxima dash red light YouTube

The car can have fault codes in the ECU even if the check engine light is not on. Use a scanner to get the codes.

could be a vacum hose problem

Check Fuel Pressure anyway Have a gauge on it when the motor runs or when your on the street Tie the gauge to a wiper so you can see it Have to find out what your loosing when it shuts off Fuel Spark

Bad ground, dead bat, dead alt

MAF sensor.

It sounds like you have a bad battery or alternator (as you guessed). Could also be corroded terminals. Check voltage at the battery the next time it starts (jump start it if you need to). If the voltage is less than 14 volts when the engine is running then you probably have a bad alternator or voltage regulator. If Voltage looks good then you need a new battery.

First thing is, check your spark plugs and leads, If these are fine get 1 liter of methylated sprites and add to a full tank of fuel... This will clean out your fuel system... Let me know whats happens...

Look for a relay block at the right front fender, under the hood. Bottom of the cover should show relay locations.

check fuel injector
