If your 1996 vehicle is having trouble staying running, especially when you give it gas, there are several potential culprits. Here are some areas to consider:
Fuel System:
Fuel Pump/Fuel Filter: If the fuel pump is failing or the fuel filter is clogged, the engine might not be getting the proper amount of fuel. This can cause stalling, especially under load.
Fuel Injectors: Clogged or malfunctioning fuel injectors can lead to a lean condition, causing stalling or poor performance when you press the gas pedal.
Fuel Pressure Regulator: A faulty regulator can cause either too much or too little fuel pressure, leading to stalling or poor performance.
Air Intake System:
Mass Air Flow (MAF) Sensor: If the MAF sensor is dirty or malfunctioning, it can misread the amount of air entering the engine, causing stalling or rough running.
Throttle Body: Carbon build-up or a faulty throttle position sensor can cause issues with air intake when pressing the gas pedal.
Ignition System:
Spark Plugs and Wires: Old or faulty spark plugs and wires can lead to misfires, especially under load.
Coils or Distributor: A failing coil pack or distributor can cause ignition issues leading to stalling.
Ignition Control Module: A malfunctioning ignition control module can cause erratic or no spark, leading to engine stalling.
Vacuum Leaks: A vacuum leak can cause the engine to stall, especially when pressing the gas pedal, as the engine will run lean.
Emission Systems:
EGR Valve: A malfunctioning Exhaust Gas Recirculation (EGR) valve can cause stalling or rough running.
Catalytic Converter: A clogged catalytic converter can restrict exhaust flow, leading to poor performance and stalling, especially under load.
Sensors and Electronics:
Crankshaft or Camshaft Position Sensor: If either of these sensors fails, it can cause the engine to stall or not start at all.
Engine Control Module (ECM): Rarely, the vehicle's main computer or ECM can have issues causing stalling.
Fuel Quality: If you recently filled up with gas, consider the possibility of bad or contaminated fuel.
To diagnose the exact problem:
Scan for Codes: Even if your check engine light isn't on, there might be pending codes stored in the ECM. A code reader can provide a starting point for diagnostics.
Fuel Pressure Test: This test can help determine if the fuel pump, filter, or regulator is the issue.
Vacuum Test: This can help identify any potential vacuum leaks.
Visual Inspection: Look for any disconnected or damaged hoses, wiring, or components.
Professional Diagnosis: If you're unable to identify the issue, consider taking your vehicle to a trusted mechanic or dealership for a professional diagnosis.

Hi there,
The general causes of a car that is starting, then suddenly dies down or quits are:
1. Ignition problems, which causes the engine to stall after starting. A possible defective spark plugs, ignition coils, mass air flow sensor or a possible leak in the air intake hose (clogged air filter).
2. Fuel delivery issues. A faulty fuel pump assembly or clogged fuel filter might be preventing a continouos fuel flow to the engine.
3. Other engine issues that can cause the engine to stall, such as faulty piston ring or a problem with the valve train.
Still, it is best to have your vehicle checked by a professional mechanic for a thorough troubleshooting and diagnostic of your vehicle. I hope this helps!

I had a 1996 Nissan hardbody xe btw ka24e engines are by far the most challenging engines I've ever had to investigate search for parts as well as complete the issues that I had. There is no straight. Forward answer to your issue especially without the type engine your 1996 has. However my best advice to resolve any issues u may have with your 96 Nissan is process by elimination oh and btw go the full mile with repair never short cut that Nissan in my experience it created more issues .., 😕
