Re: 97 buick wont start when hot

As long as you have a graphing scanner and not just a code reader. Hooking it up when it won’t start should give you a good idea. But remember that it could also be the ignition module, and or the coil pack. You can actually see the pulses from the cam and crank sensors. If it does not have fuel when it is hot my best guess would be the fuel pump relay. If you do have a good cam and crank signal when it is hot my best guess would be the spark control module
