check for a loose ground. I had similar problems about a month ago, the ground from the engine to the chassis was loose. Once that was tightened down all of my problems went away.

its by the starter, it attaches to the chassis via a bolt right under the driver side head light, you will have to pull the headlight and the bracket to get to it.

no its not. the starter will just crank the motor.

I have replaced both.

If you don't hear the fuel pump for 2-seconds after turning the ignition switch to "ON" without trying to start the engine then you need to check the fuses for the fuel pump.
