2001 Pontiac Grand Am it wont started in a cold wheather

When the problem occurs, if it is no crank or slow crank, I'd still have to check your battery and cables.

You can use a digital volt meter take a reading across the battery posts, with everything turned off, around 12.6 volts is considered a full charge. With the leads still hooked-up have a helper turn the key to crank, the reading should drop some, but not below 9 volts.

i live in miami and you know that once in a while we have a little be of a cold. this star happening to me 2 weeks ago when the tempeture drop 45 to 36 degrees
i all ready check the batery. i take to the autopart and it pass the test.also i check the wires still good.
for some reason the car wont crank at all>>>
like i say before everything work when the engine is warm!!! i guess it could be a sensor that its sending the wrong infomation to the cpm!!!!

i forgot to mension i replace the crank position sensor tempeture sensor n the shaft sensor three months ago

When the problem occurs, if there is no starter action, you may have to get at the terminals on the starter solenoid. The purple wire goes to the S terminal on the solenoid. It should be hot with the key in the crank position. Also check the field terminal, goes from the solenoid into the starter housing, that should have good voltage, with the key in crank position.

Have you tried cranking in neutral, when the problem occurs? Any testing, make sure the tranny is in park or neutral and the e-brake is set.

i still continue with the same problem!!!! yes i tried it in neutral and nothing happen!!!
i have to wait at least 2 hours so car gets warm up by the sun!!!! sounds funny but it is true!!!
this event happen everytime the weather gets cold!!!! i dont know what else to do!!!
