What would cause my Ford E-150 Van to crank but not start when I have 12 volts to the coil but no spark from the coil?

How many volts does it take to start a buick?
The normal battery voltage is about 12.6 volts with no load. Anything much less than this indicates the battery is not fully charged or is degraded. The key to starting an engine though is what does this value drop to when you start to crank the engine. If the battery is weak and the engine does not crank, the voltage could drop below 10 volts. If your car has a voltmeter in the instrument panel, note the value without cranking and then when you do crank to see how much it changes. Two six volt dry cells will produce 12 volts, but wont start a car.
Could you inform me about ignition coils?
An ignition coil is an coil that is used to change the volts in a battery to ignite the spark in the spark plug. This is necessary to get the engine to start up and the car to run.
Why would an 1989 dodge spirit start and run a few seconds then shut off twice then have no spark?
Sounds like its the ASD Relay (Auto ShutDown). Its kicking on long enough to start and run for afew then kicking back off allowing no volts to reach the coil and that means no spark... the ASD Relay also can cut the volts to the fuel pump.
When the switch is on there is 12.2 volts when you crank it is only 0.4 volts in the system?
What system? Some circuits go to 0 volts when cranking. If you are reading voltage at the battery, then the battery is dead.
Normal value of voltage in spark plug and distributor function?
spark plug produces spark in the range of 15000-35000 volts.
Which current used in cars?
12 volts DC current except the current to the spark plugs which can be 12,000 volts up to as much as 45,000 volts.
How can you make a spark plug spark with a battery and ignition coil?
You apply 12 volts to the coil primary and then release it . The electricity will go through the secondary coil and spark the spark pug.
How much spark does it take to start a yahaha xs 1100 I have 12.5 volts at the battery how much do I need at the plug?
Your voltage is not the problem. But your amperage might be. Ground the plug against the engine block and watch the spark as you turn the engine over. You should see as nice strong, blue spark. A yellow spark may mean a weak coil or a weakened points spark. Start at the coil and work your way out towards the plugs, checking each system as you proceed along.
What is 12V and can be used to create a fire?
12V is probably short for 12 volts, the voltage used by regular car batteries. And since 12V can strike a spark, it can be used to start a fire.
What is ht coil?
its a ignition coil which changes 12 volts of battery to a several thousands volts which is required for spark plug to create an ignition.
How much crank power does a Jeep Cherokee need?
a jeep Cherokee need 220 volts to run
How Many Volts Should Come Out Of The Coil?
My understanding is that it takes about 20,000 volts to arc between the two parts of the spark plug and most automotive coil put out 20,000-50,000 volts.
