How is the igniter switched on and off

There is a bad connection . Could be a loose fuse. loose wire , faulty circuit breaker . or ignition switch. If the fault is still there start at the ignition switch hot wire should be 12 volts, turn on ignition should be 12 volts on + terminal of ignition coil and 12 volts at fuel pump. if not repair as required .

Sounds like a power supply problem. Check the camshaft position sensor. its wiring connection, and the 12 volts supply line to the coil.

Hello! Check the Red/Light Green wire at the ignition switch connector for 12 volts when key is turned to start...If 12 volts is present the Ignition Module is defective...If 12 volts is NOT present the ignition switch is the culprit...Guru...saailer

The absence of spark or HT on the spark plugs is due to a failed IGNITION SYSTEM. Now this can be traced very easily. All you need is a 12 Volt park lamp, or a multimeter to check the voltage on the HT coil. you need 12 volt on the + side when the igntion is switched. if not check the fuse. Now on the other side of the coil you must have the voltage grounded ( switched by the igntion system) to produce the spark. If there is no spark the HT coil is a suspect. If not the ignition system is not switching and must be checked. failure of the electronic unit can be the reason , or lack of pulses from the pick up can be the other reason . You must be able to easily find this out by simulating the device to confirm, (feed a pulse) .

You are at thhe right trail what controls spark is coil pack crank sensor sparkplugs and plug wire but the most important is power . I mean 12 volt connections and ground This includes checking fuses you need a simple volt meter doesnt have to expensive or fancy just to pick up 12 volts let start with fuses in the engine juction box (there not mark to what it belongs to) make sure none are open. especially fuse 19 and 24 , next go to the crank sensor make sure the tabs are snuggly on now to the coil pack there is a red and light green wire this comes from ignition and feeds 12 volts at the coil pack measure that voltage is it 12 volts if not correct it this is from ignition switch ( you can make a tool that feed 12 volt with a wire and a fuse in series and attatch it to battery and the primary wire this is known as hot wire) next go to the ECM wiggle the wires see if that get a connection going if not go back to the ICM here are the wire you are to measure the tan light green, this is from ECM and it is pulsed it measure 5vlts to 0 volts switched then measure the tan orange the same thing 5 volts to zero,then tan white again 5vlts to zero. any one of these 5 to zero fails you fix is the ecm

change out your distributor cap and rotor button

the ignition coil changes low voltage from the battery (12 volts) to high voltage (about 50,000 volts) to fire the spark plugs and ignite the fuel in the engine cylinders and drive the piston down

You might not have spark as the 12 volts needs a ballast resistor or the points burn out preytty quick. 8 volts at the coil in run with the points open and 0 with the points clsed and battery voltage at the coil when cranking. coil wire near the intake manifold while cranking should jump at least 2 inches. Closed points should be 0 volts at the neg on the coil. pos and neg should be the same 12 volts with the points open. if not either the coil or the points are bad. The condenser can fail and no spark with all the rest right

No spark to the coil or is it no spark from the coil? First verify that you have 12 volts to the coil when you turn ignition switch on if not you will never have spark from the coil going to the plugs. If you do have 12 volts to the coil and still no spark you have a bad coil. To see if the coil is firing, unplug a spark plug wire from it's plug and hold it to a chasis ground while attempting to start the vehicle. There should be a strong spark and popping sound. Remember to wear leather glove or thick work glove if holding the wire by hand to avoid shock. If there is a strong spark then coil is good.

i don't beleve 3 volt is enaf for the coil it has to be at least 9 volts
if this car has a resistor on the car or on the circuit going from ignition switch to ignition coil replace it, but if it does not have one then it has to have one built in the circuit wish is going to be very hard to find i will recomed you to get straight ignition power from ignition sw, to an aftermarket ignition resistor and from there to the positive side of ignition coil,
but also let me know what promaster means? is that the brand? or is that a performance coil?
and does your car has elecgtronic? or points system ignition distribuitor.
