Several factors could prevent an engine from cranking, including a dead battery, faulty starter motor, or issues with the ignition system. Additionally, a blown fuse or a problem with the fuel system can also inhibit cranking. Mechanical issues, such as a seized engine, may further contribute to the problem. Checking these components can help diagnose the issue.
mines stop cranking because of a blown head
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.
The starter would still crank the engine but the engine will fail to run.
If the starter is engaging and is cranking the engine over but the engine refuses to run, my first guess would be the fuel pump is bad.
the cold cranking amp minimuim would be 550CCA
fender mount starter solnoid stuck or conconcern in steering colum would be a starting place
The ignition switch is defective.
Most cars would not have any oil pressure until after the engine starts turning because the oil pump is driven mechanically off of the engine.
What is a cranking system
The crank and cam sensors replace the old distributor to tell the computer when to fire the correct spark plug. The failure of either one would not prevent the engine from cranking, but would stop it from starting.
If the timing chain is off, you will probably have bent valves.
