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.
NO.
check battery and alternator
no
You turn the key, the car has energy from the petrol that makes the wheels move, this movement turns the tires and then the car moves, slowly at first but then it makes a move by using the petrol. This is CO2.
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
depends on the car you have
needs a new battery
Car won't start. Won't run. Starter will whine cause it's not cranking anything. makes a noise at the bottom of car sound like motor is about to go clicking and knocking sound
There shouldn't be a prolonged cranking time to start. Should be only two (2) or three (3) seconds at most. No year given, mileage, engine, history of car so that makes too much guess work to make an accurate diagnosis of why.
