Rodent-Chewed Wiring While Parked in Malaysia | MyMechanic
Car won’t start or shows strange warnings after parking? Rodents may have chewed wiring. Here’s how to spot, handle, and how MyMechanic assists Singapore cars across Malaysia.
What’s Happening in Simple Terms
Modern cars rely on sensors and wiring looms. If rodents chew ignition, sensor, or injector wires, the car may misfire, stall, or refuse to start. Damaged insulation can also cause shorts, blown fuses, or strange electrical behavior.
Common Symptoms After Parking Overnight
Cranks but won’t start / starts then stalls
Rough idle, fuel smell, or sudden misfire
Multiple warning lights appearing simultaneously
Cooling fans/wipers/lights behaving oddly
Bite marks, exposed copper, or nesting debris visible
Where Rodents Usually Strike
Ignition coil & injector connectors at engine top
Crankshaft/camshaft sensor wires near pulleys
O2/AFR sensor wiring along exhaust tunnel
ABS wheel speed sensor wires by struts/fenders
Main harness near battery or fuse box
What to Do Immediately (Practical Roadside Steps)
Open bonnet, torch‑check for bite marks
Don’t keep cranking—avoid draining battery
Don’t wiggle torn wires—avoids shorts
Only replace one blown fuse; if it pops again, stop
Call MyMechanic for safe help and assessment

Real‑World Scenario
After a night’s park at a hotel, car shows multiple warnings or refuses to start? Suspect rodent bites—lift bonnet, look for copper or bite marks. One chewed wire can mimic major faults. Call MyMechanic early instead of forcing it and risking module damage.
Quick Troubleshooting Cheat Sheet
Cranks, no start + fuel smell = possible injector/ignition wire bite
Multiple lights together = harness issue
Fuse blows again = active short, call for help
