I have Olds Intrigue 2000 - 3.5L. Issue engine hard to start either cold or hot.Engine light won't go on. Just hard to start. Problem was a crankshaft sensor.

3.5L engine has two crankshaft sensors. Let you mechanic to retrieve errors first.

If there is a code relevant to crankshaft censor, you will need to replace it.

Sensor in question is located above and behind starter. Starter must be removed first.

Don't go for cheap after market unit!!! Get AC Delco new one. Good luck.

Answer

How long has it been since spark plugs, wires, fuel filter been changed? Has air induction service been done? I would start with maintenance if it is due. (see: What maintenance should an owner do). Granted some of these failures may show a code, but may not. Checking fuel pressure would be one way of starting to narrow down the source. Maybe there is a pressure regulator problem. Is there any smell of raw fuel at any point, especially at the fuel rail area? Also, check to see if the throttle cable is sticking. At times, when it sticks, you will notice that the car will shift really hard into drive. That will also cause the "hard start".

Why does your Saturn 1999 sc2 not start sometimes?

If it doesn't start sometimes, that means something isn't working "sometimes". Your Saturn, along with all modern fuel injected vehicles, is a complex piece of equipment, and almost any engine component that could intermittently fail can result in intermittent starting. If it is not fuel related the computer will usually find and report the problem, so have a competent mechanic scan for error codes. If there is no error code, you probably have a problem with one of the fuel delivery components.
