Hello and welcome!

My name isCustomerand I can assist you with your question.

Expert:  Amedee replied 4 months ago.

Have you checked for codes in the computer?

Are you looking for possible causes?

Customer: replied 4 months ago.
No..!!
Expert:  Amedee replied 4 months ago.

No to which one?

Customer: replied 4 months ago.
The car will not start..I turned it off this morning and now it will not start...what can it be.
Expert:  Amedee replied 4 months ago.

It can be a lot of things. If the fuses are good, I suspect a bad computer or a bad instrument cluster.

Customer: replied 4 months ago.
Can it be the crank sensor or something like that...there is nobody on this island that can check computer....
Customer: replied 4 months ago.
all the instruments work except on the dash the fuel is showing empty but the tank is half full and there is a key symbol with a circle and a line going across it
Expert:  Amedee replied 4 months ago.

YES, it is possible that the camshaft position sensor and or crankshaft position sensor is shorting out pulling the PCM off line causing this problem. When this happens, the gauges on the cluster will not work..

Customer: replied 4 months ago.
how can I check this?
Expert:  Amedee replied 4 months ago.

You can simply disconnect the electrical connector going to each sensor, turn the key on and see if the gauges now work. If so, one of the sensors is shorting out pulling the PCM down.

Hi, Have you sent the pics or are you still working on this..Thks.
Expert:  Amedee replied 4 months ago.

YES, one minute..

Customer: replied 4 months ago.
Thanks!!
Customer: replied 4 months ago.
Thanks...I will have to find a mechanic here on this small Island in the Bahamas to check this. But do you think this might be the problem? Also, could a wire be loose in the engine bay...
Expert:  Amedee replied 4 months ago.

A loose wire would not do this..

A bad computer could do this like I mentioned.. or a shorted out sensor.. I would start by checking these sensors first.
