No fuel reaching the engine
If the engine is turning but not firing, fuel delivery problems are one of the main things to consider.

Starting fault guide
Car cranks but won’t start
If the engine turns over but the car still will not fire up, the fault is usually somewhere beyond the starter motor itself. Common causes include fuel delivery problems, ignition faults, immobiliser issues, weak battery voltage, engine sensors or other electrical problems.
Common causes
Why a car may crank but not start
Cranking means the starter motor is turning the engine, so the problem often lies with spark, fuel, timing, security systems or engine management.
No spark or weak ignition
Ignition-related faults can stop the engine firing even though it cranks normally.

Some batteries will still turn the engine but struggle to support proper starting under load.
Read guide →Immobiliser or key recognition problem
Security-system issues can allow cranking while still preventing the engine from starting properly.
Engine sensor or timing fault
Some sensor failures prevent the engine control system from delivering spark or fuel correctly.

Diesel engines can have starting faults linked to fuel delivery, glow-related systems or sensor problems.
Read guide →Signs that help narrow the fault down
- 1The engine cranks strongly but never tries to fire
- 2The engine almost starts, then cuts out
- 3A warning light stays on while cranking
- 4There is a fuel smell, misfire or rough running before the problem began
- 5The issue happens more often when cold, hot or after standing
How to approach the problem more sensibly
1. Confirm what the car is actually doing
Cranking but not starting is different from clicking, no-crank or a completely dead battery.
2. Check for warning lights and messages
A dashboard warning may point you toward immobiliser, engine-management or charging-related clues.
3. Avoid replacing random parts
Starting faults often feel similar from the driver’s seat, even when the causes are completely different.
4. Get the cause confirmed properly
Basic checks, fault-code reading and inspection usually save more money than guessing.
