Saturn SC2 Hot Start Problem
I have a "new" Saturn. It's a 1999 SC2, same 1.9 Liter engine
as the others. Problem is that it start fine when cold. After driving for 10 minutes or so, I turn the engine off at the store. Walk out after 2-3 minutes and turn key. NO START. the starter doesn't turn over. Doesn't even click the solenoid. I wait another 5-10 minutes and it starts right up. No problem. I changed the temperature sensor on the block with a new one. No help. Any ideas? Car runs great, other than this "Hot Start" problem. By the way. NO check engine light. NO battery low or charge light. Once it sits for a few minutes, turning the ignition off, then on - it starts like normal. Go figure. kim |

Saturn SC2 Hot Start Problem
If you do not even get a "click", then I'd suspect one of the following:
corroded/dirty or loose battery, starter, or engine block connection defective or dirty starter solenoid contacts defective starter relay defective ignition cylinder switch Bad battery (not likely, but there could be an open cell) I'm not sure why it behaves differently when cold or warm. You also do not say if the lights, radio, blower fan, etc. all still work or not when it will not start. My guess is this may not be dependent on the temperature so keep your eye on this ... at the minimum, I'd remove, clean (with a wire brush), and tighten both the positive and negative battery posts and connectors. I'd also do the same with the engine block and starter connections as well while the battery is disconnected. Good luck Bob .. > wrote in message ups.com... >I have a "new" Saturn.

As I said, after a few minutes more cooling time it starts normally. Battery functions the same, start turns over and start just like normal, no noticable drain on the batter. Not even a hard start. thanks. Kim |
