    i see... but what if the security light is on? will that effect the car getting started up. when we purchased it they didnt have the key so we bypassed it... when we did we tried starting it up and the starter is cranking the fuel injectors are working but the sparkplug isnt sparking.

    my uncle owned the car and had it parked for years and never fixed it so when we were ready to pick up the car, he didn't have the key at the time so we just broke the ignition so we can pull it, now we have the key from him and tried to start and we are having the problem that was mentioned above

    The title of your help request is different from what you are asking. The ECM is located under the passenger side floorboard. Lift up the carpet and you will see a wooden panel. Remove the panel and you will have access to the ECM.

    Just to clarify, the sensor I am talking about is mounted in the front left of the engine on the timing belt cover.

    There is a sensor on the front left of the engine that is known to cause what you are describing. Try tapping on it while someone turns the engine over. Does the check engine light come on when you turn on the ignition. If it doesn't, your ECM is not powering up. You mentioned the fuel pressure is high, are the fuel injectors clicking? If they are that tells me the ECM is powered up and getting a signal.

I don't think I understand how you bypassed the key???? You didn't provide any of those details in your first help request. I don't think it will start when the security light is on. Unitl you are able to provide all the details I don't think I can be of much assistance.

1992 300Z doesnt start on the first try


When ws the last time you had your vehicle professionally tuned up? You could be experiencing any one of infinite possible issues. Your problem sounds most like a fuel delivery/mixture issue, but could be anything, including poor wiring/connections. Have a pro look at it!

Cant find the fuse


there isn't a fuse on the starter wire from the ignition. if you are not getting a connection it is more than likely a problem in your key cyclinder.
when you move the key into run (right before you attempt to crank) do you hear the fuel pump prime? usually this sounds like a gush of air and liquid.

Car wont start


Fuel delivery must be confirmed with a fuel pressure gauge on this vehicle. Disconnecting the fuel line and cranking the engine to see fuel shooting out does not confirm pressure, it only confirms fuel delivery. Remember you need both fuel delivery and pressure. On this vehicle if the psi is off by just one number that's enough to keep it from starting. Also replacing the coil and rotor (as you stated) does not confirm that spark is reaching the plugs. Confirm that both spark and adequate fuel pressure are reaching ALL the spark plugs.
