Non-start situations basically boil down to two things: No Fuel, or no spark.

I you are looking to throw a part at it, start with the crank sensor. They are cheap and not too hard to replace.

A full diagnostic approach would be to determine if it was a fuel or a spark problem. Check fuel pressures with a fuel pressure test guage: Low fuel pressure indicates a bad fuel pump or a bad fuel presssure regulator. Lastly on the fuel side, check t see if the injectors are getting a signal to fire, usually done with something called a noid light, I believe.

Spark diagnosis begins with first determining the condition, then finding the cause. Bad coil, loose wires, even the crank sensor are all suspect. A good repair manual with a flow chart is probably the best procedure to follow.

In my case, my manual only had a passing reference to the crank sensor and no diagnostic procedure to test it or even lead me to it. I found the solution through extensive web searches. Once I replaced it, all was well.

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

I HAVE A 98 SATURN, WON'T EVEN TRY TO START EVERY ONCE IN A WHILE. TURNS OUT TO BE THE CRANKSHAFT POSITION SENSOR

SOURCE: ok i got a 2002 saturn vue..code was saying bank 1

I had exactly the same problem .Mine was corrected with replacing the O2 sensors .The sensors cost less than $30 each but cost about 20 mins labor per sensor .So if you got an honest mechanic the total cost will be around $130 .
