The electronic engine control wiring harness insulation may be damaged due to copper spikes produced during the welding of its wires. This creates a potential for a short circuit between the wires which energize the fuel pump, causing some fuel injectors to open, discharging fuel into the engine. Consequence of defect: fuel discharged into the engine would eventually leak through the exhaust system to the ground. This could result in a fire if a source of ignition is present.
Repair wiring harness, check engine and catalyst for damage.
Vehicle description: light trucks equipped with 2. 9 liter engine. System: electronic engine control wiring harness.
