ok i need some advise for my supra. It sometimes won't turn over when i am trying to start it. this seems to only happen when the weather is warmer. when its cold i have to let it warm up for an average 10 minutes or it stalls on me. on my super monitor it diagnosed 12,14...which meant crank angle pulse, and igniton signal. i'm not sure if this has anything to do with my starting problems but i really need some clues on what the hell im supposed to do...
starting problems...

- Start date
Won't turn over...means the engine does not crank, like no starter. Is that what you mean?? Or does it crank, but won't start???
The Supra doesn't have a crank angle sensor. 12 is RPM signal, typically the distributor or distributor wiring. 14 is ignition signal, typically coil, ignitor, or wiring. If the motor isn't turning over then it's a starter problem with a 99% probability of the starter contacts being the culprit, cheap and easy to replace. If the motor turns over but doesn't catch then the 12 and or the 14 codes are your problem. Try wiggling the wires connected to the distributor, coil and ignitor and see if the car starts normally.
12 is definitely the CPS/dist wiring... my car wouldn't start, i wiggled the CPS wires and it started fine... Also pulled code 12.
The click is probably starter contacts. Very cheap to replace, just drop the starter and put the new ones in. After that you can start diagnosing your other problems.
If you leave the B+ line on, and disconect the ground from the battery, it wont actually hit the ground when you drop it.
