Question about 1989 Buick Park Avenue

1 Answer

Jesse I have a 1989 Buick Park Avenue. sometimes i can crank it and it will run normal. But most of the time the only way i can crank it is holding my foot on the gas and not letting off. if i let off the car will die. Also that's the only way i can drive it also with my foot staying steady on the gas. like if i'm at a red light i have to hold the brakes and gas at the same time or the car will die. What's causing this?

I haved a 1989 Buick Park Avenue 3.8 engine...I have replaced the starter, coil pack, ignition module, crank sensor and cam sensor and still cannot get it to fire...I really NEED this car to run so PLEASE...


ok ! did you mean its got spark but does not start. if spark but does not start. check to see if its getting fuel to engine. remove air hose from throttle body and spray some starting fluid in throttle body, open throttle plate and spray some in. if car starts then stops, its a fuel problem. if no spark check the harmonic balancer on engine to see if its loose, the 3.8 engine have a crank position sensor that runs off the balancer. the rubber starts wearing out and the balancer start flopping around. and the timing gets massed up. good-day ! type in on pc browser ignition switch symtoms, and a list of things will come up. for a ignition switch controls over 50% of voltage for vehicle. good-day !

My 1990 Buick Park Avenue dies after 15 miles


Replace the crank sensor as they get hot they will sometimes quit working. The temp light comes on everytime the engine is turned off and the switch is on. Next time it dies spray or pour some water on the sensor then see if it will crank and if it does you know what it is.
