1996 ford probe gt slow to start in the morning, but you can turn the engine off and start it again and it will start right up drive it some days and it runs fine drive it others and it is sluggish and sputtering like it has a fuel or spark plug problem.
Did you proof read that? If you're trying to say it has a long crank time before it starts for the first time in the day, suspect fuel pressure is leaking down overnight. That can be due to a leaking fuel pressure regulator, leaking check valve in the pump, or a leaking injector. If you turn the ignition switch to "run", then pause there for two seconds before cranking the engine, and it starts quicker, suspect fuel pressure bleeding off. That doesn't hurt anything; it's just annoying.
