I'm not a expert like the big dogs on the website. But here is my two cents. My newphew is a ASE certified mechanic at the Ford garage. He told me some time ago if a car won't start then the two places to start are. Is the engine getting fuel. Is the engine getting spark. If its not getting fuel its the fuel filter or the fuel pump. If its not getting spark we'll thats a completely different ballgame. Meaning that where his trouble shooting expertise would have to come in. I seen him pull out small like jumper wires to bypass stuff to locate a problem. I WAS BLOWN AWAY WHEN I SEEN THAT.
