Buick Roadmaster
The odd one out in Buick's range and the reason to check before assuming: this is a rear-drive, body-on-frame car with a small-block Chevrolet V8, sharing its B-body with the Chevrolet Caprice and the Cadillac Fleetwood, while every other Buick of its years is a front-drive V6. The 1994 change to the LT1 brings Optispark ignition — a distributor mounted at the front of the block beneath the water pump, which fails when the pump seeps and is the first thing to establish on a damp-weather no-start. The estate's rear-facing third seat and its tailgate mechanism are its own.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
