Before you start swapping components you will want to narrow down where the
problem is  - spark or fuel. When it won't start check for fire at the
plugs. No fire then go through the ignition system. Lots of spark then you
will have to work your way through the fuel system, from the fuel pump
onwards. If the temp sensor is flooding your engine you should smell lots of
gas at the exhaust. I seem to remember reading somewhere about a temporary
short you can make to the temp sensor to check if it is causing problems...
