94 Altima, drivin along, just lost power, still had radio & lights, will turn over but will not start
Very good possibility that the Fuel Pump has gone out.
Find the Fuel Port on the Fuel Rail going to the Fuel Injectors. Remove the cap. Pack plenty of rags or paper towels around that area. Wear goggles to protect your eyes from Gas Spray! Using another wadded rag or paper towel partially covering this port and a small screw driver - depress the stem inside this port. Have a partner turn the Key over attempting to start the vehicle. A strong stream of gas should come out.
If no gas is coming out: check the Fuel Pump Relay/Fuses. Use a Voltmeter to check for voltage at these locations. The reading should be 11+ to 12 -volts.
If there is Voltage: Again with a partner behind the wheel, remove the gas cap. Place your ear up very close to the Gas Filler Tube (where you put gas in). Have your partner turn the key over to the On (not Start) Position which is the position just before Start. You should faintly hear the Fuel Pump humming. Have your partner turn the Key to the Start Position, again you should hear a very faint humming (over the car cranking).
If there is not indication of humming: Jack-Up and properly support the rear of the vehicle with jack stands. Once again with a partner behind the wheel: go under the vehicle and place your ear up close or on the gas tank. Have your partner turn the Key to the On Position. You should hear the humming.
If not, have your partner turn the Key to the Start Position. There should be humming.
If no humming there is a great chance your fuel pump has gone out.
Based on your year (1994) this is highly probable.
HOWEVER: If there is humming, change out your Fuel Filter and recheck for fuel at the fuel rail.
