Hello I have a 300zx n/a automatic and I put my car away about 2 years ago and have decided to pull her from the dust and low and behold I turn the key the engine cranks but refuses to start or even sputter. Well I then started tearing it apart and ran the codes on the ecu and got codes for the coolant temp sensor,maf sensor, and the cas sensor replaced them all still no start. I then pulled the plugs after cranking for a minute and found only cylinder 5 was wet with fuel all the others dry as a bone and I took off the fuel lines there is plenty of preasure. So then I moved to the fuses and relays all of them tested fine so basically I'm now lost and hoping someone has run across the same problem I suspect ground issues but they didn't look to suspect. Someone please jump in and take me to school. :confused:

It sounds like the injectors may have been gummed stuck from sitting . Did you replace the gas before starting it, two year old gas definitely doesn't help the starting at all? Have you check the state of the injectors? You can always pull the CAS and spin it with the ignition on and see if the injectors click.
