What causes long cranking?
When an engine cranks for a long time before it starts, either spark or fuel is missing or weak and each has its own reasons. A bad coolant sensor, a bad throttle position sensor (TPS), a bad fuel pump or a plugged fuel filter can all cause a lean condition causing long cranking times.
What happens when fuel sensor goes bad?
A faulty rail sensor may upset the air fuel ratio and cause the vehicle to experience performance issues such as a decrease in power, acceleration, and fuel efficiency, and in some cases may even experience stalling.
Can you drive with a bad fuel sensor?
Engine stalling might occur as the fuel rail pressure sensor goes from bad to worse. You will be driving and then suddenly, your engine will stall. This will make driving extremely difficult (and dangerous) and it should motivate you to do something about it.

What can cause a fuel pump not to work?
The most common cause of fuel pump failure is frequently running the tank low on fuel, which causes the motor to overheat.
