Question about 2000 Saturn Ls 4dr Sedan

2000 saturn want start after driving for a while

Saturn sometimes want start, after driving, sometimes it sits for two hours before it start..... My 2000 Saturn LS has a similar problem. After driving for a while, then sitting for 30 minutes or so, it won't start. It will crank over just fine but doesn't start. It has always started in the morning before work and in the afternoon when I get off work. It will start if I have been driving and shut it off for a short period of time, such as getting gas. But if it sits for a little longer, I have to wait about 2 - 3 hours before it will start again. It runs fine once it is started. Any ideas?

Saturn has had a problem with bad crank position sensors which are fairly cheap and easy enough to replace. (about $20 or less)

When the sensor gets hot, it won't work, so after cooling down it will work again. If you test it, it must be tested when hot otherwise it will test fine, please let me know if you have any more questions and I would be glad to help.

good luck

You are likely experiencing vapor lock. Changing gasoline grade, or getting a vented gas cap may help.

My 2000 acura 3.2 tl is misfiring. I've replaced the spark plugs. It starts and drives fine until you park for 5 minutes and when you go to start it up again, it misfires badly and sometimes won't start at...


Check the wiring. to Coil, plugs, Crank Positioning Sensor. check to see if the wire is in good condition sometimes if wire is checked, in poor condition it will allow bleed through especially when the wires get hot. This is why it will often start when engine cools down and why it shuts off when your sitting cause it heats the wires up there is not the cool air running accross the wires when sitting. Good Luck and a grt day. Would appreciat 4 thumbs up if this was helpful.

After driving for 25-30 minutes, the car won't start for about 3 hours


Any chance you've got 'Titanium' spark plugs. We had this same issue, and found it was caused by a mechanic replacing our plugs with the titanium ones. If they were hot, they didn't ignite properly during startup. If you let the car cool, it would start right up (~2 hours). Changing the plugs for good quality old-style plugs and the problem hasn't occurred since.
