car won't start

[friostang]

Well ask yourself if you have made any modifications lately. What did you do to it last before it started acting up? What size engine is it? Was it overheating? If it overheated for a while it could be a cracked head or bad head gasket. Did you have an accident and it got bumped around? There is a reset switch in the truck somewhere that is automatically cut off in case of accident and car will not start until that is reset. Does the car turn over with the starter or is the starter not even trying? Did you adjust timing at anytime? Is the coil wire connected? Are your spark plug wires correct? Lots of info missing sorry.
