My 90 Buick LaSabre will not start when hot. If I let it cool 15 minutes it starts right up. If I leave it in park running I will get a yellow service engine light, that will go out once I begin driving. Any ideas.. 140K... runs good
Could a faulty water pump cause the engine not to start when hot ? I do hear on occaision some squeeling .. But i don't understand not starting when hot.. Any ideas V6-3800- 3.6
