* Fuel Pump Issues: The most probable cause. Even with gas in the tank, a faulty fuel pump won't deliver it to the engine. This could be due to a failed pump, a bad fuel pump relay, or a blown fuse related to the fuel pump.
* Cranking but not Starting: You said it won't start, *but did it crank?* If the engine cranks (turns over) but doesn't fire, the problem is different than if it doesn't even crank. Lack of cranking suggests a battery, starter motor, or related electrical problem.
* Immobilizer System (if equipped): Some 1994 models might have an immobilizer. A problem with the key or the system itself could prevent the engine from starting.
* Distributor Issues (if applicable): Older vehicles often use distributors. A problem with the distributor cap, rotor, or ignition coil could prevent the engine from firing. This is less likely given you just added gas, but possible.
* Spark Plugs/Wires: While less likely to cause a complete no-start after refueling, worn spark plugs or faulty ignition wires can prevent a proper spark.
* Security System Issues: Aftermarket security systems, if installed, could be interfering with the starting process.
Troubleshooting Steps:
1. Check the Battery: Make sure the battery has sufficient voltage. A weak battery may not have enough power to crank the engine, even with gas.
2. Listen for the Fuel Pump: When you turn the key to the "on" position (not starting), you should hear a brief hum from the fuel pump. If you don't, the pump or its relay might be faulty. This is usually heard near the fuel tank in the rear.
3. Check the Fuses: Inspect the fuses related to the fuel pump and ignition system in the fuse box.
4. Check for Spark: If you have experience, you can check for spark at the spark plugs. This requires some automotive knowledge and tools.
5. Try a different key (if applicable): If there's an immobilizer, this is worth a shot.
If you're not comfortable performing these checks yourself, it's best to call a roadside assistance service or have a mechanic diagnose the problem. Attempting repairs without proper knowledge can be dangerous. The issue is likely electrical or fuel-delivery related, not simply running out of gas.
