Your fuel heater (inside the fuel bowl under the filter) has probably shorted. You need to disconnect the heater (either at the funky-looking spade connector about halfway down the side of the fuel bowl driver's side OR at the little spade connector inside the fuel bowl driver's side), replace the fuse and see if it starts. This is the usual problem for your symptom. Cheers!

The heater is like a 16ga wire. Would that really be able to blow a 30 amp fuse? I even put a 40 amp in there by mistake and blown. There is no damage to the heater wire.

It's not the wire it is the element inside the fuel bowl that shorts out so you do not burn up that wire and any other along the way . Either pull the wire as Patrick suggested or pull filter and clip/cut the element .

Thanks for the help. The heating element was the exact problem. Now I need a new icp sensor.
