Unless the EGR position sensor is shorting out the 5V reference, NO. If you suspect the sensor, simply unplug it & see if the starts.

Would a defective crank position sensor cause a 1997 Dodge Caravan not to start?
It is possible, but not guaranteed in every case. The crank position sensor is a little bit redundant, since there are other sensors available to the engine's control module, which could give it essentially the same data required for the engine to start and run. Regardless, if the crank position sensor is found to be defective, it should be replaced.
On a 94 3000gt If your o2 sensor is faulty will it not start entirely or will it be dead in the water?

Will a Crank position sensor make a engine not crank?
No, it will crank, but it will not start.
Symptoms of a defective mass air flow sensor on a 4.3 engine?
Won't start and sometimes back fires when cranking.
What happens when a crankshaft position sensor goes bad?
When a position sensor is going bad the engine could run rough, or cut off for no apparent reason. Or, the engine may not start at all.

What does a crank shaft sensor do?
AnswerIt reads the position and/or speed of an engine as it is rotating. When crankshaft is turning, the sensor will provide a signal to the PCM. The PCM will then allow the engine to start by providing spark and fuel.
