1998 Oldsmobile Bravada ProblemsCheck Engine Light Due to Gas Cap Issue
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The electrical contacts in the ignition switch may fail and result in erratic instrument panel gauge operation or illumination of the Check Engine Light. A failed ignition switch will require replacement.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
1998 Oldsmobile Bravada QuestionsCold weather start problem. Alt., batt., connections ok . Suspect fuel delivery? (1 answer)
Cold weather turns over but won't start. Usually try short turnover intervals otherwise battery runs low. When warm weather I don't pump pedal, it starts. I bought new 700cca battery, now cranks faster but still takes 4+ cranks to start. Alternator, cables, connections are good
I have replaced the 2 upstream o2 sensors and one downstream (the one after the catalytic converter) where is the fourth sensor?
