- Clogged fuel filter: This prevents the flow of fuel from the tank to the engine.
- Faulty fuel injector or fuel pump: This can disrupt the fuel supply to the engine.
Fuel-pressure issues:
- Leak in the fuel line: Insufficient fuel pressure might disrupt starting or cause the engine to die.
Vacuum issues:
- Leak in the intake manifold gasket or vacuum hose: Air leaking into the engine through a leak can disrupt performance.
Electrical issues:
- Alternator: It needs to function well enough to keep its battery sufficiently charged.
- Ignition coil problem: This will disrupt spark delivery
- Starter problems
- Worn brushes
