* Fuel Pump: A failing fuel pump might deliver fuel initially but then struggle to maintain pressure, leading to the engine stalling. It could have completely failed now, preventing the engine from starting.
* Fuel Filter: A clogged fuel filter can restrict fuel flow, causing similar symptoms.
* Crank Position Sensor (CPS): This sensor tells the engine's computer the position of the crankshaft. A faulty CPS can cause the engine to run erratically or not start at all. It's possible the heat from running the engine briefly caused a failing CPS to fail completely.
* Cam Position Sensor (CMP): Similar to the CPS, but for the camshaft.
* Ignition System: Problems with the ignition coil, spark plugs, or wiring could cause the engine to run briefly and then die, as the components may overheat or become intermittently faulty.
* Mass Airflow Sensor (MAF): A faulty MAF sensor provides inaccurate air readings to the engine's computer, leading to a rich or lean fuel mixture which could cause stalling.
* Throttle Position Sensor (TPS): A bad TPS can give incorrect throttle position data to the computer and lead to similar issues.
* Alternator: While less likely to directly cause the initial problem, a failing alternator could have drained the battery enough during the initial two-minute run that it's now too weak to crank the engine.
What to do:
1. Check the Battery: Make sure the battery terminals are clean and tight. Test the battery voltage. A weak battery won't crank the engine. If the battery is weak, charge it fully before proceeding.
2. Check for Spark: Have someone crank the engine while you check for spark at the spark plugs. If there's no spark, you'll need to investigate the ignition system components.
3. Fuel Delivery: Listen carefully near the fuel tank while someone cranks the engine. You might hear a faint whirring sound from the fuel pump. If not, the fuel pump is a strong suspect. (Note: this is difficult without experience, and there is a risk working around fuel).
4. Have it Checked Professionally: Given that the car now won't start at all, it's best to have a qualified mechanic diagnose the problem. They have the tools and expertise to test the various sensors and components mentioned above. Attempting some of these repairs yourself without the proper knowledge and equipment can be dangerous.
Ignoring the problem could lead to further damage. Get it diagnosed and repaired promptly.
