My 2004 Buick Lesabre cranks but will not turn over when the engine is warm, such as when I m stopping at a store for a half hour or so. When I wait for 1-2 hours it will start.
The car often sputters when I make brief stops and I can sometime coax it to turn over. But I have needed it towed two times. If I can let it sit for an hour or two, the car cools down and can start normally again. The mechaniccannot find the problem since he has it when it is cool and the problem is intermittent. This problem makes the car unreliable.
If the car is not cranking it could be one of several things. Starting with the easiest...... (1) bad battery (2) corroded battery terminals (3) bad connection at ground or starter (4) bad starter
Sorry I somehow hit post before finished.... I would check the battery terminals, but the problem is probably the starter, it is not uncommon for them to act up when the get hot...they get hot from the exhaust manifolds near them. Some cars have heat shields to keep the exhaust manifold heat off the starter.
