Engine will not start after turning the engine off

Asked by Jun 04, 2013 at 01:48 PM about the 2008 Buick LaCrosse CXL FWD

Question type: Maintenance & Repair

I bought a used 2008 lacross cxl, with a 3800 Series III engine. After purchase the dealer had to replace (under Warrenty) the  ignition Module which was shorted, and also found and replaced number 1 coli cracked- other 2 coils are blackened-Ignition module is shorted and ignition fuse open."  Two to three times a month, after using the car (shopping) the engine cranks but does not start. It sounds like and engine without gas. I wait awhile and try to start it again and it fires up. Don't know if this is part of the problem but sometimes, the air bag indicater light next to the speedometer lights up for not reason.
