My mother drives a 1993 Buick Century that will not start when the engine is hot...?

We have recently replaced the starter, battery and alternator, but the problem persists. Any ideas?My mother drives a 1993 Buick Century that will not start when the engine is hot...?Have the trouble codes checked by a technician.My mother drives a 1993 Buick Century that will not start when the engine is hot...?Hey Bob,

Is her car fuel injected? If so, the fuel sensor can be bad. Try putting cold water on the sensor when it won't start..if it starts, it's the fuel sensor. If not, back to the drawing board. :)My mother drives a 1993 Buick Century that will not start when the engine is hot...?check the valve clearances could be tight when its hot and loosing compression
