as far as hearing the fuel pump, that maybe initial prime. After that, there has to be rpm signal for pump to run. If your missing everything, I agree with you, I'd have to check cam and crank sensor. Did you check sensor wiring circuits before replacing? The diagram is for crank sensor, you can see wire colors, three wires, 5 volt ref--signal--ground. the pink wire with yellow tracer is ref voltage, key on, anything there? You can use digital multimeter to check, I don't know how bright a test light would work with 5 volts? If no ref voltage, unplug the tps see if ref voltage comes back? If it does, I suspect something going on with tps. I'm not telling you to replace anything, you need to do some testing. Any applicable trouble codes?
