    All the research is saying one of 3 things
    1) Battery Connection. Make sure that battery connections a clean and tight
    2) Starter
    3) Safety Switch, Turn the key to crank and move the automatic lever around a bit to see if you can get it to work

    Did you replace the safety switch?

My problem was the neutral start safety switch. The switch is right under the battery. It probably has a small crack, and when it heats up, the contacts open. Car thinks it is in gear, and won't crank. It happens only once a month for me, so I just open the hood and pour a bottle of water on the battery, it runs on the switch and cools it down. Car starts every time. New switch is $300, some day I'll replace it.

First i would check the crank sensor by looking for rpm's on the tachometer or scan tool if you see any rpm's then crank sensor is good.Then check for leaking injectors and if they are not leaking then you will need to check the ECM it may have failed.

After I drive my jeep some, if it is somewhat warm or not cold weather, my jeep has a hard time starting. It may crank but run a little ways and cut off going down the road.I have had the coil, plugs, plug...

if it shuts off after running for a while and will not restart for about 10 min,a bad crank sensor will cause this. abad crank sensor will make car shut off and not restart for about 10 min. put a scanner on to make sure. a check engine light does not allways come on. if you do not have a scanner, any auto parts store will scan it for free.

Saab 9-5 Aero Wagon 2000 wont restart when warm or after running

I have a 1999 Saab 9-5. I had a similiar problem. The car would always run cold. It would get hot and the engine would quit. It could be anywhere. One mile from start to 50 miles from start. Once it cooled down it would re-start but the cool down time was always different. Only difference for me was my car would crank, just not run. Replaced the crank position sensor ($60), no more problems! Good luck!

Will not start when it is warm,let sit for 15-30 mins..starts

Which engine is this? and also do you have a TACH gauge?

check for spark when it wont start there is a common problem with the loss of crank signal on these cars with 2.8/3.1 engines.

If you have no spark its either a crank sensor or the ignition module going bad, but the problem is you need to verify which one it is. having a tachometer would help diagnois this. if you have a tach signal and no spark most of the time its an ignition module but you would need a lab scope to 100% know which one it is. the modules are very common on these engines.

what happens is the crank signal goes to the igintion module. and then the module loses it most of the time cause the module is supposed to send the crank signal tot he ecu. you would have to make sure the signal makes it out of the module and into the ecu. if you get a signal out of the module then you have more severe problems. that need in depth diagnosis.

9000 won't start!

Sounds like a crank sensor. They can drive you mad. If you hear a clicking sound when you try to start it, that is the battery. But if you turn the key it starts, you drive some place turn off the car for 5 minutes and then try to restart it, and it does nothing at all, that is a classic crank sensor.
