2005 Dodge Neon Has no fri at plugs,no pulse at injectors and starter will not turn with key.

Most common issue is the camshaft sensor.

Ok then so what is you question.????????

First check the Timing belt next cam sensor CPS then the throttle position sensor TPS they work together so to tell if all of the internal parts are in line. That way they will not bang togather.

check for battery terminals ,starter fuse ,check if key has chip inside. use original key,.maybe new battery,chek that first,and we go from there.

Check for disconnect hose or a vacuum leak

The ASD relay powers the injectors and the coil.
Have you checked it to see if you have power in and out ?
The engine computer grounds the starter relay, injectors and coil, could be something going on with it.

ck see if firing at plugs ck see if has fuel pressure could be timing belt

Camshaft Position Sensor-On top of engine Operation The Engine Management System (EMS) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The EMS constantly monitors the number of pulses on the signal circuit. The EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the EMS. Some engine management systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the EMS misfire diagnostic will likely be affected.
The following symptoms can be caused by an intermittent wiring connections or faulty signal to the EMS.

bad plugs, broken plug wires, bad injectors

it sound like you have a bad crank sensor when the sensor gets hot it open circuits inside the sensor and you loose spark if you have access to a noid light see if you are loosing injector pulse also if so then you know its a good chance its the crank sensor
