We have a 2006 infinity FX 35. When attempting to start the vehicle, it rapidly cranks over but will not start. This has happened 5 times since we purchased the car new, averaging about once a year although the last time there was only about a two month interval between episodes. We learned that in order to get it started, if we inserted the key, and after cranking it a few times to see if it would start, if we took it out of park, turned the steering wheel, put it back into park, then it seemed to start right off as if nothing was wrong.

The FX is a bouncy car, but it's necessary to accommodate it's good performance. You can try some aftermarket air shocks, or check into different tires. That should help.

Sounds like the fuel pump is shorted.

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!!!

You could have a locksmith recode the key cylinders and cut you new keys for much cheaper.
