Hi,
I've not come across that particular symbol before, but anything showing a key is usually about the ignition systems.
Since it's not starting, my guess would be that your key isn't disarming the immobiliser.?
Have you got another key for that vehicle which you could try instead.?
Best of luck.

I just fixed the problem with the 96.
Crank no start
No fuel pressure
No spark
No volt gauge and no fuel gauge
No scanner obd working when hooked up says error no communication. With the help of this awesome guy randy from washington, i did some relay jumping, more wire tracing and found it was the crank sensor was shorting out with just the key on. with key on, locate the crank sensor behind the valve cover, unplug it and see if everything comes back on, this is what it did for me. Thanks again randy for the help and this gentleman can be reached @ http://www.aceautomotive1.com.

Assuming I understand your problem correctly, it sounds as if the car will only start once the check engine light comes on. The check engine light is controlled by the PCM (powertrain control module; or computer) which is also responsible for basically all engine operations including fuel delivery, ignition, emissions, and so on. If this light is not coming on, it means that the computer is not getting power. If the computer is not getting power then it won't start. The fact that you hear the relays click on when the light comes on is another indicator the the computer is not getting power as it also supplies power to the ASD (Automatic Shutdown Relay) which in turn supplies the power to the fuel and ignition systems. Check the ASD relay located in the power distribution center, if it is the same relay number as another un-important system, then swap it out to see if that helps. Make sure the plugs going into the computer are tight. The delay in the power going to the PCM sounds like a stuck relay, have someone tap the relays when the light is off to see if comes on. It is also possible that the PCM itself is failing.

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.
