I've had an intermittent no-start condition on my 2000 Buick Park Ave. This started happening on occasion and was nerve racking. Took it to my local mechanic shop and he replaced the crankshaft position sensor which solved the problem. Found the problem with the sensor 'A'(18X24X) out of range. Code PO336-CKP. in the computer. Hope this info will help others who have this problem.
