Car won't start, have to cycle the key random amount of time to get car to crank. Have replaced the camshaft pos sensor about 9 months ago and did the crankshaft pos sensor last week.

Call autozone and ask them to define the codes for ya then get with your mechanic and get em fixed.
SOURCE: car won"t start. starter turns. Happened once before. started after 30-45min.
I would start by banging the bottom of the gas tank while you are cranking it over. If this causes it to start, replace the fuel pump. If it still doesn't start, there is a valve on the fuel rail on the top of the engine (you may have to remove plastic cover). Remove the plastic cap on the valve, and while you have someone cycle the ignition to the run position from the off position, depress the center tab on the valve and see if gas comes out. If it doesn't, replace the fuel pump. If it does, let me know and I will help you further. (note: replace fuel filer at same time.)

yes it can stop vehicle from starting,but i would call a mobile mechanic to check it out for you,start changing bits willy nilly and it will cost you more in the long run.
SOURCE: turn the key and nothing happens,no crank,no sound,no start
It seems that you have a loose wire, bad connector or perhaps the main computer itself that is causing a problem If the shop is not seeing any codes, or codes come and go, likely I'm right...but someone is going to have to actually do some intensive testing to find the real cause. You can likely get another computer from a local scrapyard far cheaper than what the dealer will charge you...as far as wiring, you need a good accurate schematic a good volt/ohmeter and lots of time to trace wiring. When checking connectors test the pin, then probe the wire going into the pin...often the problem is where a wire meets the backside of the pin, either corroding or breaking..This also applies to any modules such as the security system...what you see on the dash does not always tell you that connection to components is good. This is not a "fix, but rather, a direction to go in. (exactly what I"d need to do if I was there)
Right now, everything is suspect including fuel system, till you rule it out!!!
