What Causes the Buick GL8 Engine to Make a Clicking Sound and Fail to Start?
2 Answers
There is abnormal noise but the engine fails to start, possibly due to spark plugs or fuel supply issues. Below is a detailed analysis of the specific causes of engine abnormal noise: Loose screws on the engine underguard: A relatively common minor issue, tighten or adjust the screws on the engine underguard. Aging engine mount pads: Mount pads support the engine and need replacement once they age. Loose plastic components in the engine compartment: Such as the engine cover or intake pipe, simply tighten them. Abnormal noise from the engine belt: Including the power steering belt and alternator belt. Aging, overly loose, or overly tight belts can cause noise, requiring replacement or tension adjustment.
When encountering a Buick GL8 that won't start and makes a clicking sound, it sounds like the starter is spinning freely. I've come across many such cases, and the common issue is usually a low battery charge. The GL8, being a heavy MPV, demands a lot from the battery. Insufficient charge can lead to inadequate starting current, causing the starter to just click. It could also be due to wear in the starter itself, such as gear slippage or poor relay contact. Another possible cause is a charging issue with the alternator—check if the battery terminals are oxidized or loose. It's advisable to try charging the battery first or use an onboard tool to test the voltage. If it repeatedly fails to start, avoid forcing it to prevent damaging components. It's best to visit a professional repair shop where technicians can use diagnostic equipment to thoroughly inspect the entire starting system. Regularly monitor the battery's lifespan and replace it every two years or so to minimize such problems.
