It jumps? look for a broken motor mount

A cars tach jumps and runs with engine rpm.Sometimes if it jumps and changes engine sound,the throttle position sensor needs changing.If it jumps with no engine speed or sound change it means your alternator is going bad.
Usually It's torn or broken. Some are liquid filled and will leak. To check: Open hood so you can see the motor, start motor, keep your foot firmly on the brake pedal, put car it drive and give it a LITTLE gas and see if motor lifts or moves excessively. do the same in reverse. If it jumps around you know you need mounts, don't forget to check the trany mount also. Most mount problems are caused by oil leaks that rot out the rubber mounts.
that would be your engine, it cause your car to die with no way to crank it or anything, that happened to my Jetta once, it jumped time allot.
the motor mount is bad
If it literally "jumps", it's a bad motormount.
the season for the jumps starts usually round november.
my friend jumps up and down.

The amperage draw at motor start up will be roughly 300% of the FLA (Full Load Amperage) of the nameplate rating.
If it is very far out of time it will not start

if the valves clear the pistons if it jumps time
No, if anything motors need time delay fuses in the start up phase of their rotation. The motor will draw up to 300% of their full load amperage. Time delay fuses get the start up current past this phase of start up.

A soft start allows a motor to speed up slowly instead of dumping full current on the motor it ramps up. A simple capacitor can do this aided by a switch inside the motor that opens the cap circuit when it gets up to speed. Modern motor controllers can be programmed to give you a soft start.
