2016 Isuzu Truck NO-START CONDITION – CLICKING OR BANGING FROM STARTER 2012-2015MY Isuzu N-Series Equipped with 5.2L (4HK1) Diesel Engines It is possible to experience a no-start condition accompanied by a clicking or banging-type noise from the starter. This condition presents itself when vehicle battery voltage is low. The insufficient voltage/current will cause an improper ground for the X-17 starter relay. As a result, the starter will not remain engaged to start the engine. This is not an indication of a defective starter, alternator or ECM. The following is a list of common causes for low battery voltage.
Inspect these items as possible causes for the described condition before further diagnosis. 1. Extreme low ambient temperatures (below 10°C / 50°F). The chemical reactions inside of batteries take place more slowly when the battery is cold. The vehicle systems therefore have less energy to work with when it tries to start the engine. 2. Vehicles stored for long periods without proper battery charging and maintenance. 3. Batteries that have been relocated further away from the starter than the original designed location. 4. Batteries or battery cables that have been replaced with improper gauge. 5. Corroded battery terminals and cables. 6.
Vehicles that are started and stopped multiple times without allowing the charging system to replenish the batteries’ charge. 7. Excessive use of electrical equipment such as electric lift gates. 8. Interior and exterior lighting left “On” without the engine running. NOTE: Do not diagnose starters, alternators, ECMs or other no-start conditions prior to ensuring the battery is fully charged and none of the above common causes exist Fuel Tank Caution Fuel fill kit must be installed on cab chassis if it will be driven for an extended distance (Note: fuel tank kit provides venting for the fuel tank.
DO NOT RESTRICT OR KINK THE FUEL TANK VENT HOSE Operating this vehicle with a restricted or kinked fuel tank vent hose may cause serious damage to the fuel tank and/or fuel injection pump. Continued operation may cause engine failure. PAGE 1.9
