Can you tell me how much a shifter cable should cost about for a 2005 Pontiac Sunfire and how many hours it should take to put in?

Busted shifter cable , not moving shift lever out on the transmission . Your best bet , take it to a mechanic .

sounds like you should junk it,so many questions, 1997 sunfire gt shifter cable Bing images

First, check transmission fluid level, if low may not be able to pump, may need trans filter and fluid change.

Check that as you move the shifter, that the shifting rods beneath are moving in tune with the shifter's position.
If not, then your mechanism is faulty.
It is almost certain that the issue lies with the external shifting mechanism.
The issue may be just beneath the shifter lever, within the rubber or leather bag shroud. You might have to pull out the centre console to have a closer inspection.

With out knowing more of your symptoms it is hard to say. Turn on your head lights for a second and make sure they are nice and bright, This tells you two things, you have power in you battery and you have a good connection to the car. Next with the headlights turned on try starting the car,have someone watch the headlights to see if they dim when the car tries to crank. If the headlight intensity does not change and you don't hear an audible clicking sound coming from under the hood check to see that the shifter is in park or clutch is fully depressed. If that is ok you are likely looking at a ignition switch problem or the starter itself is bad. Can you tell me if the dash lights up or if you hear the car go click when you try to start it?

What you are asking a stranger to do is, go on google.com and find some salvage or auto recycling
yards and find a price for a shifter box for that car. And the reason you can not do this yourself? You have the advantage of knowing where you live so you could determine which are local and hence no or low shipping costs.

SOME THING HAPPEN OR WASN'T PUT BACK RIGHT IN THE SHIFT LINKAGE WHEN IT WAS PUT BACK IN.......

gas line could be crushed or clogged up. but first try the battery might be dead try changing it, the starter could be messed up, or the ignition relay. try the relay before buying a starter. if at last the dont work i would have a code reader put on it and see if anything shows up the reading with cost u but will save some time

it sounds like your shifter cable , you gonna have to remove the shifting console to remove the cable in one end in the other end I belive is 2 bolts is pretty easy just make shure the shifter is on first if it is auto and neutral if it is manual

Most likely the shifter is defective.
