What causes a car to run lean on a hill?
If the fuel filter is not changed for a long time, eventually the particles and sediment from the gas tank will build up and clog the filter, restricting fuel flow. If the flow of fuel is restricted too much, not enough will be able to reach the fuel injectors and the car is likely to run lean.
Why does my car run flat on its face when going up a hill?
A symptom of starving the car for fuel is a car that runs correctly at idle and low load, but falls flat on its face as you ask for more power (when climbing a hill, for instance). Fuel pumps may fail due to age, sediment buildup, or running the incorrect fuel.
What to do if your car is losing power while driving up hills?

What causes a car to start at the wrong time?
Spark plug wires are a source of electromagnetic interference (EMF), but this is usually only a problem on some aftermarket setups when this interference isn’t taken into account. A timing belt or chain that has skipped a tooth will throw off the cam timing, causing the intake and/or exhaust valves to open at the wrong time.
What happens when a car starts and then dies?

What causes a car to start but not keep running?

What causes a car to start and then die?
But if there is a fuel leak somewhere, then the proper amount of fuel won’t be able to make it to the combustion chamber. This might cause the engine to still start, but it won’t be able to keep it running. That is why it will die almost immediately after it starts.

What causes a GMC truck to turn over but not start?
If the engine starts up normally after doing that, it means that fuel pressure is bleeding off and the fuel pump needs to prime the lines before it can start.

Why does my car turn over but won’t start?
