have you checked the ignition switch, for broken wires? Is the security light flashing? I think this model had a small black chip on the key, in the center above the cuts. If so wire to the key reader may be broken and it is in theft mode. It will disable the fuel and spark. Sounds like you already ruled out all other possible problems.

it doesnt have that type of key but are there other ways that it could be put in theft mode even without that type of key?
