Replaced spark plugs, wires, crankshaft sensor, and the cam one. When I check to see if they are firing the only one that's senses any power is the cam sensor. Now the car is turning over but no start. What would be the problem now? The guessing game has me without money. I can't figure out the problem. Please someone help.

So, we need to start with backing up a step to find out how you are checking the cam sensor and saying it is the only thing that is getting power.

Basically, if you have no spark then that could be due to a number of things.

So, let's start with making sure the theft light is not on.

If the theft light goes off after the key is turned on, then we need to move onto a crank sensor issue.

One good thing to determine this is if the RPMs move slightly when you are cranking the engine. If it doesn't move at all then we need to suspect, there is a crank sensor issue.

If you don't have a scan tool that can graph the pattern of the crank sensor then we should at least check the voltage coming from the sensor.

If we can confirm there is at least voltage coming from the sensor when it is cranking, then we can move on for now.

See the wiring diagram below and let us know what you find.
