[DelLawson]

Buick GL8 failure to start is usually due to a dead battery, incorrect gear position, etc. Below are the relevant details: Common causes: Dead battery; Incorrect gear position; Spark plug failure; Circuit malfunction; Fuel filter failure; Mechanical failure; Engine carbon buildup; Steering wheel lock; Engine water ingress. Solutions: If the engine can start normally, an emergency method of short-circuiting terminals 30 and 50 can be used to start it. Successful starting indicates a fault in the starting control circuit. First, check if the starter fuse is blown, then replace it with a relay of the same model to rule out a faulty starter relay. Next, inspect the starter key wiring, and finally check if the ignition key contacts are functioning properly.
