The possible reasons for the GAC GS4 failing to start include: dead battery, empty fuel tank, or incorrect gear position. The following are related details: 1. Empty fuel tank: If the fuel gauge shows below the red line, it indicates insufficient fuel. 2. Dead battery: This could be due to a drained battery from leaving the headlights on for a long time or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) position to start. If it is in R (Reverse) or D (Drive), the vehicle will not start. Some manual transmission vehicles will also fail to start if the clutch is not depressed.

I've been driving for over a decade and have seen many cases of GS4 failing to start, mainly due to battery aging or starter motor failure. Older GS4 models are prone to electrode corrosion causing poor contact in humid weather. I personally encountered this issue with my old car - when turning the key, it only made clicking sounds, and it turned out to be severe spark plug carbon buildup with unstable air-fuel mixture concentration preventing ignition. For prevention, regularly check battery health; use a multimeter to measure voltage - if it's below 11V, it needs charging. Northern owners should pay extra attention to adding battery insulation covers in winter. Another common issue is loose fuel pump wiring harness, especially in vehicles manufactured before 2017. It's recommended to check engine bay connectors monthly to ensure they're securely plugged in. If the problem recurs, don't delay - immediately visit a professional shop to inspect the chassis or ignition system to avoid compromising safety.

My Trumpchi GS4 previously wouldn't start, no matter how hard I tried in the residential area – it was really frustrating. Later, a friend suggested it might be a blown circuit fuse or a faulty crankshaft position sensor, especially during cold starts when the issue occurs more frequently. I also learned that a clogged fuel filter can cause insufficient fuel supply, and moisture on the ignition coil can prevent sparking. Now I've become wiser: I turn off the air conditioning before parking to save battery power and keep it fully charged; during rainy days, I apply silicone grease to connectors to prevent oxidation. Regular car owners can perform basic checks: first, see if the dashboard lights come on – if not, it's likely a battery issue; if the lights are on but there's no sound, the starter might be stuck. Don't attempt random disassembly; it's more reliable to have a trusted repair shop check the fault codes.

In GS4 repair practice, ignition failure is quite common, most frequently caused by relay malfunction or enlarged spark plug gaps. Check the ignition coil for cracks or leakage, and listen for the fuel pump's humming sound during startup - if silent, replacement is needed. Poor battery terminal contact is another frequent culprit, solvable by sandpaper polishing. The 2015-18 GS4 ignition module has a design flaw making it prone to water ingress and short circuits, requiring protection. Quick fixes: measure battery voltage, inspect the engine compartment's 15A fuse (replace if dirty), and don't overlook loose wiring connections - tightening critical junctions can prevent issues.

Researching automotive technology, I found that GS4 ignition issues are often caused by electronic control failures, such as insufficient ECU power supply or sensor signal interference. Analyzing several cases revealed that the fuel pump relay has poor contact under vibration, leading to significant cold start difficulties. Battery terminal corrosion increasing resistance is another cause, suggesting upgrading wire thickness for corrosion resistance. Environmental impact is substantial, with electronic components overheating and failing in high temperatures. For solutions, connect a diagnostic tool to read fault codes and clean throttle valve carbon deposits to prevent clogging. Daily maintenance requires attention, focusing on whether the starting current remains stable.
