We have a '03 Pontiac Grand Am GT, 3.4L (3400).

If the resistor bypass doesn't solve it, another remedy could be a plug-in type engine block heater- I mean plug into household current. It keeps the engine coolant warm in the block. Every other car here in Montana uses one-works great for those below zero nights. When the wife pulls into work, just run an extension line and keep the car plugged in till time to go. Other than that, IDK, sounds like you've covered it pretty well as far as solutions.

Crank but won't start

You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, fuel pump, or a list of other things.

'Service Traction' indicator comes on, car stalls, won't restart. What's happening here?

Someone will need to scan the body computer for trouble codes to proceed. A simple code reader may not access the body computer.

you need to hook up a diagnostic code retrieving tool to the aldl < assembly line diagnostic link > this is located under the instrument panel on the drivers side, plug the tester into the link, then turn on the ignition key, but do not start the vehicle, the tester will cycle through the computer , and will retrieve any trouble codes that the computer has picked up, once you have recieved the trouble code or codes, write them down, and then turn off the ignition key, and unplug the tester, then compare the codes to the code booklet, and then it will tell you what the code stands for, and then you can check those areas to see what the problem is, also if you do not have a tester, a auto part store will check this for free, hope that this information has helped you.

Check engine light came on and said map sensor. car has a rough idle, no power at take off. New map sensor was installed and car issues were not resolved. H E L P ! ! !

Did you clear the trouble codes with the scanner? OBDII trouble codes must be cleared with a scanning tool. If the codes are not cleared the computer could be in the"limp home mode". Once the codes are cleared, drive the car for at least one day. If there is no improvement, scan the engine again for codes.
