The 1998 Buick Skylark has 4 recalls, all carrying fire risk: two fuel system defects can allow gasoline to leak near ignition sources, and a damaged ignition switch can start a fire inside the steering column even with the key removed.
The fuel-related concerns involve aftermarket replacement parts. A Delphi fuel pump module assembly with reversed vent and return tubes can deliver an overly rich fuel mixture, causing the engine to run rough or stall, and can also allow fuel to leak from the evaporative emissions canister. A separate Delphi fuel pressure regulator, sold without an O-ring and retainer, can leak fuel at the regulator itself. Either fuel leak raises the risk of a fire under the hood. The ignition switch issue is worth noting because the danger persists after the driver walks away: if the engine fails to start and the key is held in the start position too long, the high current passing through the switch can melt internal components. Once that damage occurs, the steering column can catch fire on its own even after the engine is off and the key is out of the ignition.

What can fail
Certain Delphi fuel pressure regulators (part numbers FP10020-11B1, FP10026-11B1, FP10027-11B1) sold as aftermarket parts lack an O-ring and retainer, which can affect fuel system function.
What the fix does
Delphi will replace the defective fuel pressure regulator with a corrected unit at no charge.

What can fail
Certain Delphi aftermarket fuel pump module reservoir assemblies have reversed vent and fuel return tubes. This can cause rough idling or stalling due to overly rich fuel mixture, or fuel leakage from the evaporative emission carbon canister.
What the fix does
Delphi will replace the defective module reservoir assemblies at no cost. Contact Delphi at 1-877-335-7443 for service.

What can fail
Holding the ignition key in the Start position for too long can cause high current to overheat and melt internal switch components. A damaged switch can ignite a fire in the steering column even after the engine stops and the key is removed.
What the fix does
A relay kit will be installed to limit current flowing through the ignition switch and prevent overheating.

At a glance
What can fail
When the engine fails to start and the key is held in the START position for an extended time, high electrical current flows through the ignition switch and can generate enough heat to melt internal switch components.
What the fix does
A relay kit will be installed to limit current through the ignition switch. The dealer will verify proper starting with a charged battery and replace the ignition switch if needed.
