We can't ignore the specifications provided in the service manual. That taken into account, resistance is not the best way to test. Dynamic would be better, was the voltage in spec with new trigger when you tested it?

Pickup coil resistance • Disconnect the A.C. magneto coupler from the wire harness. • Connect the multimeter(Ω × 100) to the pickup coil terminal. Tester (+) lead Green/White terminal ① Tester (–) lead Blue/White terminal ② • Check the pickup coil for the specified resistance. Pickup coil resistance 459 ~ 561 Ω at 20 °C (68 °F) (White/Red – White/Green)

I just tested my spare, it's new 439 ohms off the machine.

New or not, I don't believe that pick-up will work at 119 ohms. I've never seen one that is working less then 400 ohms. Whe you test it, is it off the machine?

Sounds like you have a short somewhere. Difficult to help with electrical problems without performing the tests. Follow the service manual step by step. The problem will be small and most likely due to corrosion, broken wire, or bad connection. Make sure your battery is good, very important! They wont run in many cases due to something as simple as low voltage.

Based on your description of the problem, my guess would be a short or not enough current due to some added resistance, blown fuse, or simply a weak cell in battery.

If those two components pass, check resistance in spark plug cap and replace plug. Check for spark again. If all that is good, check fuses, main switch, wiring connections for entire ignition system. Most importantly, check the battery for a minimum of 12.6 volts! 9.6 volts while cranking!

. Pickup coil resistance • Disconnect the A.C. magneto coupler from the wire harness. • Connect the multimeter(Ω × 100) to the pickup coil terminal. Tester (+) lead Green/White terminal ① Tester (–) lead Blue/White terminal ② • Check the pickup coil for the specified resistance. Pickup coil resistance 459 ~ 561 Ω at 20 °C (68 °F) (White/Red – White/Green)

I would look for a short to ground. Also, check coil and pick-up. I know u replaced trigger, check it anyway! Primary coil resistance 0.18 ~ 0.28 Ω at 20 °C (68 °F) • Connect the multimeter(Ω × 1k) to the ignition coil. Tester (+) lead Orange lead terminal Tester (–) lead Spark plug lead • Check that the secondary coil has the specified resistance. Secondary coil resistance 6.32 ~ 9.48 kΩ at 20 °C (68 °F)

Check out the service manual download forum. If you can't find it there, google it. You will need it to find the problem, the manual provides specifications and testing procedures. The camshaft sensor should be located near stator. Look at the service manual, it can be called several names, trigger coil, pulsar, etc. You must test and eliminate each component separately before buying new parts. You will need a service manual and multimeter for testing. Most of the time, the problem will be small, generally a short on the ground side of the circuit due to corrosion or loose wire. The problem will require resistance, voltage drop, and continuity testing. You must be methodical and pay strict attention to detail

Would need more information as to the make or model. A coil usually has a positive and negative and the wiring goes to a CDI, ECM or some other form of igniter. The pick up coil, pulsar, trigger coil (or whatever you choose to call it) is often located at the stator and is activated by a reluctor on the flywheel or near the crankshaft depending on the type of equipment. Sounds like you have a short based on the information provided. You will require a wiring diagram and a multimeter to troubleshoot the various components and circuits.
