battery, solenoid/starter or relay or even ignition switch
NO.
this question makes no sense ? i assume you mean prevent the car from cranking??? if so then no. a bad fuel pump may stop the car from running or starting but it should not stop it from cranking. a bad fuel pump relay could stop the car from cranking but that would depend on the year make and model of your car.
check battery and alternator
no
Weak battery
when cranking the engine the battery voltage should not fall below 9.6volts if so replace battery
cold cranking amps is the rating on a car battery- the higher the number of cca the stronger the starting power of the battery
NO
needs a new battery
depends on the car you have
put your key in the ignition and turn it and hold it till it stops cranking. k.
A street car makes frequent stops.
