What is the reason for the Wuling Rongguang having fuel and spark but cylinders 3 and 4 not working?
2 Answers
Wuling Rongguang having fuel and spark but cylinders 3 and 4 not working may be due to faulty spark plugs or abnormal ignition coils. Below is a detailed introduction about the Wuling Rongguang: 1. Overview: The Wuling Rongguang has a length of 4 meters, a width of 1620mm, and a height of 1915mm. Compared to traditional microvans (under 3.8 meters), it is larger in length, width, and height, providing more space for both passengers and cargo. 2. Exterior: The Wuling Rongguang EV largely retains the design style of its fuel-powered counterpart. The front features a narrow grille with honeycomb elements and large headlights on both sides.
I've worked in an auto repair shop for several years and have seen plenty of Wuling Rongguang minivans. It's quite common to encounter issues where cylinders 3 and 4 fail to fire despite having fuel and spark. First, ignition components are prone to problems: worn spark plugs or incorrect gaps in cylinders 3 and 4 can cause misfires; faulty ignition coils or distributors may also affect specific cylinders. Second, fuel injection system: clogged or leaking injectors can disrupt fuel supply, especially since Wuling injectors tend to accumulate carbon deposits over time. Then there's compression: worn piston rings or excessive valve clearance will show low compression during a cylinder pressure test. Electrical issues shouldn't be overlooked either: loose wiring harness connections or faulty ECU sensors can cause single-cylinder failures. I recommend starting with a simple check of spark plugs and injectors, then moving to professional tools for compression testing if needed. The Wuling Rongguang is economical and practical, but if cylinders 3 and 4 keep failing, it will lead to poor acceleration and engine damage—prompt repair is essential. The repair costs aren't high; replacing the faulty parts usually does the trick.
