Re: Technical Difficulties
Welcome to the garage.
I´m not sure if the fuel level indicator signal comes from the PCM (as is on the WJ), but if it does, then it looks as an internally shorted crank sensor. Disconnect this sensor and see if the fuel level indication comes back. If so, then change the sensor. Also the battery voltage indicator signal comes from the PCM and will stay at 0 when the crank sensor is shorted.
Regarding the fuel pump, you should be able to hear it work for a few seconds when you put the ignition switch to run. You could also check if there is fuel available at the fuel rail by pressing the schräder valve and see if fuel under pressure comes out.
