Why does my Car Crank but won’t fire up?
Worn spark plugs can cause a “cranks but won’t fire up condition.” Worn spark plugs produce a weak spark that’s not hot enough to ignite cold fuel.

What should the crank speed be for a cold engine?
If the rpm reads 0 (zero) while cranking, there is a problem in the speed/timing circuit, or the engine cranking speed is below 100 rpm. At least 100 RPM is required to achieve reliable starting. b. The cranking speed is typically 100 to 150 rpm with a cold engine.
