A vehicle that will not start or cranks without firing requires systematic diagnosis of the starter circuit, fuel system, ignition system, and engine security systems.
DIAGNOSE NO-STARTBattery voltage, starter motor draw, and ignition switch output tested. Eliminates the most common no-start cause in the first 15 minutes.
Fuel pressure at rail, injector pulse and ignition coil output tested under cranking conditions to confirm the engine is receiving fuel and spark.
Immobiliser, transponder key, CAN bus and ECU communication verified. Coded key or module reset performed where necessary.
A no-start condition has a logical cause — battery, starter, fuel, spark, or immobiliser. Hallmark technicians follow a structured no-start diagnostic protocol that identifies the fault within the first visit, avoiding parts replacement by guesswork.
Battery CCA and voltage measured. Starter draw tested. Eliminates the most common no-start causes first.
Fuel pressure at rail measured under cranking. Fuel pump relay and fuse confirmed. Injector pulse signal tested.
Coil output, crank and cam sensor signals checked. Immobiliser status read via diagnostic tool.
Faulty component replaced or reprogrammed. Vehicle started and operated to confirm fault is fully resolved.
A single click indicates the starter solenoid is engaging but the starter motor is not turning — typically caused by a discharged or failed battery, a corroded battery terminal, or a seized starter motor.
Cranks-but-won’t-fire means the starting circuit is working. The fault is in fuel delivery, ignition, or engine management (immobiliser, cam/crank sensor). We test all three systematically.
Yes. We carry OEM-level programming tools for BMW, Mercedes, Audi, Land Rover, Porsche and all European marques. Key coding, ECU synchronisation and immobiliser re-learn are performed in-workshop.
