Sorry about that I had it in my head you had a hhr. The code P1682 ignition switch circuit could have been set from crqnking it without it starting and the battery voltage dropping too low. There is a bulletin for that code setting because of that condition. The P0300 is random missfire the P0443 is evap purge solenoid control circuit. The P0102 is mass air flow sensor performance. The P0102 can be caused by the same reason the P1682 can low battery voltage.I would have the battery tested make sure the alternator is charging properly also make sure the battery cables are clean and tight. Also have a back pressure test done to make sure you dont have a plugged cat. That could set a random missfire code the mass air flow code etc.

Again you would have to have the abs codes read which most basic code readers wont do. Without seeing what codes are settingits hard to say.

Your best bet is to get the codes your setting rather then looking for a needle in a hay stack.

So I started the truck up this morning took it for a 20 minute drive ran good. Tried to start it an hour later engine cranked but it didnt fire off. I got the battery tested it was perfect. Went to get the alternator checked napa and advanced could not test the alternator. Went to the dealer told him what happened he thinks it is the throttle body. He said it is common on that truck. Ialso told him when you turn the ignition to start it you can let go of the key and the engine will still try to start he told me that it is fine that it is suppose to do that. I am going to shoot ether in it and see if it fires if it does does that mean the throttle body is bad. I also called another dealer they think it is that or the pcm or bcm. I have already experienced this with my 1992 cadillac devillle not a fun job. The one dealer is charging 650 to install it and the other is charging 500. The 500 dollar one seems like he knows what he is talking about. If I wanted to put it in how hard is it to do. Thanks for your help.
