I can start and drive my car and then go to start it again later and it wont start but I can try it again 5minutes or longer later and it starts fine but then it does it again. whats the problem
GM cars have bad problem with security system. If you key turn light and will start other time will stick and need shaking to turn over and won't start just replace the key. Security system need some times to refresh the memory.
1.turn key ON for 10min.
2.turn key OFF 10sec.
3.turn ON 10min.
4.turn OFF 10sec.
5.turn ON 10min.
turn OFF ON and start
total of 30 min. to refresh the memory
the next step is more expensive and need some skills.
on top of the ignition switch is a sensor go bad
replace ignition switch with the sensor and do the learning process from step 1 to 5

Sounds like a bad starter solenoid, usually cheapest and easiest to replace the starter and solenoid as a unit. It is always best to check for power between the solenoid and the starter with a test light, if the solenoid clicks but the test light doesn't light up you have found the problem in the solenoid.

so you changed the air temp sensor because ginko wrote the same thing in solution 8 how about coolant temp sensor

you have a bad battery, if it more than three years old it is suspect, measure voltage it should read 12.5v minimum, if not trash it and install a new one. but also it could be as simple as very corrosion on the cables and post, if they look dirty, clean up with a wire brush real good and tighten it down firmly. Batteries are designed that if you lost you alternator and are just running on battery power and the car finnally gives up, if you wait another an hour, it has a reserve capacity that will allow you a couple more miles usually. i was stranded in the desert one time in the middle of nowhere 60 miles from home and used this technique, i had to do it three times before i got home but then that thrashes the battery and you'll have to replace it. Make sure that your belt is not loose and that its charging up the battery as you drive. You can also check this my monitoring your analog gauge to see if its on the plus side, if you don't have this gauge, then just use a voltmeter and check it while running, it should be around 13v, if its charging the battery.
can you rate this. thanks!

SOUND LIKE ALTERNATOR NOT CHARGING BATTERY.CHECK BATTERY VOLTAGE SHOULD BE 12.6 VOLTS.MAY SURE BATTERY CABLES CLEAN AND TIGHT.WITH ENGINE RUNNING CHECK ALTERNATOR OUT PUT AT BATTERY.SHOULD BE 13.5 - 14.5 VOLTS WITH ENGINE RUNNING.IF ALTERNATOR FUSE GOOD AND ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES OKAY NOT DAMAGED.DRIVE BELT NOT SLIPPING OR BELT TENSIONER NOT DAMAGED.ALTERNATOR MORE LIKELY FAULTY.TURN OFF RADIO FIRST.BEFORE REMOVING NEGATIVE BATTERY CABLE TO KEEP FROM LOSING RADIO CODE.
