Did you install a new fuel pump? Because the fuel level sender is part of the pump. There are hoses that connect to vapor recovery from the tank check and make sure they are not lose. Take the cap off and clean where it threads in. I have seen where gunk builds up and does not let the cap seat properly because it isnt going all the way in.get a new cap at the dealership. I bought new caps at the parts store and the light still came on.got the correct one at dealer and as soon as i started my car the light went off .

I can make a couple of suggestions here. First for oil to be leaking there must be a leak from a bad gasket...either from the head, (hope not) or head cover gasket....easy fix. It may be as easy as tightening down the covers. I would change the head cover gasket and make sure it is tightly screwed down.
Second the correct oil is 20w50 and preferably not a synthetic.
You will see an improvement in the oil pressure if you are not using 20w50.

Possibly the starter solenoid mounted on the starter. When it won't start, you could check for power at that small solenoid wire on the starter while the key is held in crank or start position. If you have power then and there, the solenoid should be replaced. If no power on that wire when key is held in start, it is somewhere else in the start circuit, like the neutral safety switch, or clutch switch if manual, or the starter relay or the wiring associated with it.

there was mod to sort this out way back, the air flow connector plug was prone to corrosion a repair kit was used to fit a new connector with gold plated contacts but check the wiring back to ecu or try retensioning the connector female contacts with a small watchmakers screwdriver or similar and apply contact grease, or you may have air leak after the air flow meter hope this helps.

Most fuel-pump relay units are located under the dashboard near the steering column. In some cases, the unit is located in the area where the steering column is mounted or near the engine's firewall. The end of the fuel pump relay is typically located near the center of the floorboard, under the carpet in the front section of the passenger's or driver's side footwell.----------------------------------------------------------------------------------
