* Air in the Fuel System: This is the most likely culprit. When you changed the filter, even a small amount of air entering the lines can cause the engine to stall. The pump initially pushes the air through, then runs out of fuel until the air is cleared. Repeated starts eventually exhaust the ability of the fuel pump to prime.
* Fuel Pump Issues (Less Likely): While unlikely caused by the filter change itself, a weak fuel pump *could* exacerbate the air-in-the-fuel-line problem or be experiencing its own separate failure. A weak pump might struggle to push fuel past the air.
* Other Potential Issues (Less Likely): Though less probable given the symptom, other problems like a clogged fuel injector or a crank sensor issue could exhibit similar behavior but are less likely to be related to the filter change.
Here's what you should do:
1. Check for Air in the Lines (Most Important):
* Listen Carefully: After the engine dies, listen closely near the fuel filter and the fuel pump (usually located in the fuel tank) for gurgling or sputtering sounds. These indicate air moving through the lines.
* Visually Inspect (If Possible): If you have transparent fuel lines, look for air bubbles. This is less common on a Silverado, but worth noting.
2. Cycle the Key: Turn the ignition key to the "ON" position (without starting the engine) for 10-15 seconds, then turn it off. Repeat this several times. This can help prime the fuel pump and draw fuel into the lines. Try starting the engine again.
3. Check for Fuel Pressure: The best way to diagnose if you have an air problem is to measure fuel pressure. This requires a fuel pressure gauge and knowledge of your Silverado's fuel system specifications. If the pressure is low or fluctuating, you have a fuel delivery problem.
4. Check Fuel Filter Installation: Double-check that you installed the fuel filter correctly. Ensure the arrows on the filter indicate the correct fuel flow direction. A reversed filter can cause issues.
5. Bleed the Fuel System (If Applicable): Some vehicles have bleed screws or procedures to manually bleed air from the fuel lines. Consult your Silverado's repair manual to see if this is an option.
6. Consider the Fuel Pump: If the above steps don't resolve the problem, you may need to have a mechanic test the fuel pump's output to rule out a weak or failing pump.
Important Note: Gasoline is flammable. Work in a well-ventilated area and avoid sparks or flames. If you're not comfortable performing these steps yourself, take your Silverado to a qualified mechanic. They have the tools and expertise to properly diagnose and repair the issue.
