On really hot days, the car will not start. Remote will unlock doors, radio will play and electric windows will work. Dealership has been unable to diagnose problem. Has anyone else had this problem?

    Any more information - Do the dash gauges work? It the theft system warning light on or flashing? Does the engine turn over and not start or does it not crank over at all?
    Please give more information if you can.

    The gauges do not work, the car does not crank--it is silent, the theft deterrent light is flashing.

    Check battery connections and make sure both are tightened. Then turn key on with security flashing, wait until the security light quits flashing, turn off key wait a couple of seconds and try starting car. This will reset the computer on car. I had same problem when battery connections became loose.

    The gauges do work, the theft warning system flashes, but the engine does not crank at all.

    I have this problem ongoing in a 1990 Olds Toronado.....Someone that owned it previously hacked into the ignition wire to add an alarm system.I either have to unhook the battery everywhere I stop or I have to get a jump. I thought I had eliminated the problem when I changed out the starter enable relay, but when the weather warmed back up, the problem returned. But only during hot weather..It starts immediately upon jumping..Acts just like I had unhooked the battery..It's almost like the jolt of the jump forces it to start..This has been plaguing me since I bought this car..I never had this problem with my other Trofeo and I am to the point I want to get rid of my car. Otherwise it works wonderfully..

    I originally had this problem but the dealership eventually (it took 2 years) found that there was an electrical short.

    I ran into a similar problem with my Pontiac check your fuel pressure. my car would run great and have no issues first thing in the morning or after a couple hours of cooling off. I had a faulty fuel pump. motor was overheating and causing car not to start. has been running fine for 6 months now
