I have Cadillac SLS (1998) and I was driving and felt a jult, then 5 seconds later it just cut off and wouldn't re-start. I tried to start it again, but it didn't. I let it sit for over 5 hours, then a complete day, and it only turns over and doesn't start. If it is something electrical...what could it be? or could it be a fuse of some sort that I can change myself? Do you know of any tests that I can perform myself with auto tools such as a volt meter to find out what the problem may be?

Thank you for your time and consideration.

You need to find out if its fuel or spark problem do below and see what happens

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil,distributor pick-up coil, ignition control module, cam and crank sensors-
