Fuel delivery problems and smart key or immobilizer faults account for most of the rest. The sound the engine makes when you turn the key tells you a great deal about which one you are dealing with.<\/p>\n<h2>Symptoms That Tell You Why Your Land Rover Discovery Won\u2019t Start<\/h2>\n<p>Pay attention to the first two seconds after you press the start button.<\/p>\n<ul>\n<li><strong>Rapid clicking, dash lights dim:<\/strong> low battery voltage or loose, corroded terminals. The Discovery runs a heavy electrical load, so a battery that still powers the lights can be too weak to crank.<\/li>\n<li><strong>One loud click, no crank:<\/strong> usually the starter motor or its solenoid.<\/li>\n<li><strong>Cranks normally but never fires:<\/strong> fuel or ignition. Think fuel pump, a clogged filter, or crankshaft position sensor.<\/li>\n<li><strong>Nothing at all, no dash lights:<\/strong> a dead battery, a failed main ground, or a blown fusible link.<\/li>\n<li><strong>Dash message about the key:<\/strong> a weak key fob battery or an immobilizer fault keeping the engine from starting.<\/li>\n<\/ul>\n<h2>Checks and Repairs When a Land Rover Discovery Won\u2019t Start<\/h2>\n<p>Start with the simple items before replacing parts.<\/p>\n<ol>\n<li>Check the battery terminals for white or green corrosion and make sure both clamps are tight.<\/li>\n<li>Have the battery load tested. A resting voltage near 12.6 volts is healthy; under 12.2 volts it is discharged.<\/li>\n<li>Try the spare key or hold the fob against the marked start location on the steering column to rule out an immobilizer issue.<\/li>\n<li>Listen at the fuel tank for a two-second pump hum when you switch the ignition on.<\/li>\n<li>Have the stored fault codes read. A proper scan tool reaches the body and engine modules, not just generic engine codes.<\/li>\n<\/ol>\n<p>On a Discovery, a replacement battery normally has to be registered to the charging system so it charges correctly. A straight swap without registration shortens battery life. If testing points to the battery itself, that is a <strong>Battery Replacement<\/strong>; if the codes point to wiring, modules, or the immobilizer, it becomes <strong>Electrical &amp; Diagnostics<\/strong> work.<\/p>\n<h2>When to Call a Mechanic<\/h2>\n<p>Call for help if the Discovery won\u2019t start after a jump, if a new battery drains within days, or if the dash shows multiple unrelated warnings. Those patterns point to a parasitic draw or a ground fault that needs measurement, not guesswork. Never crank repeatedly for long stretches; you can overheat the starter. If your vehicle has an open safety recall, check it on NHTSA or at Land Rover USA.<\/p>\n<p class=\"novo-cta\">If your Land Rover Discovery won\u2019t start, book a Novo Repairs mobile mechanic and we will diagnose it in your driveway.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Can I jump start a Land Rover Discovery?<\/h3>\n<p>Yes. Use the marked jump posts under the hood rather than the battery itself, and follow the sequence in your owner\u2019s manual.<\/p>\n<h3>How long does a Discovery battery last?<\/h3>\n<p>Typically four to six years, less in very hot climates or with frequent short trips.<\/p>\n<h3>Does a dead key fob battery stop the engine?<\/h3>\n<p>It can. Most Discovery models let you start the vehicle by holding the fob against the designated spot on the column.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When a Land Rover Discovery won\u2019t start, the cause is usually a weak battery, a corroded ground connection, a failing starter, or a fuel or immobilizer fault.
