98 ST350, not firing
Have a 98 St350 workhorse, it will not fire. I put my spark tester on it, and it fires just a little when the pedal is pressed, then quits, it also fires a little when you let up on the pedal, when the solenoid disengages. Has a new igniter on it, and all the grounds are good, will not fire on either cylinder. Any help would be great. I am about out of options.

Re: 98 ST350, not firing
Was it running fine prior to this and just quit or have you replaced the engine?

Re: 98 ST350, not firing
Finally got a hold of a manual for this thing, the ignition coil checks out on both coils, and the pulsar is also in range. When I turn the engine over, I get no voltage at all coming from the pulsar, it seems like there ought to be some kind of voltage pulsing from that coil, but I don't know. Anyway, I'll keep on trying. I clean and checked all the battery and ground connections, and even replaced the terminal ends on the battery. I am stumped.

Installed a new pulsar coil, still no fire. Has to be a wiring problem.

Re: 98 ST350, not firing
If it helps any, when I got the cart, the blue wire that connects to the green wire coming off the accelarator microswitch was connected to the main ground that comes off the accessory wirng harness in the dash, and it had a 36 volt solenoid on it.

Re: 98 ST350, not firing
Could you find an igniter to swap out and check. From what you've checked it sounds like the only other option. That part isnt cheap so if you could find a loaner it would help. I would definitely take the diagram from the tech forum and bactrack my wires to check for loose or bad conn. or a wire cut or worn into from something. Also mak sure your pulsar is picking up the signal from the flywheel. Good Luck!!

Re: 98 ST350, not firing
I have a brand new igniter on it. I talked to a tech at ezgo, and they said they think it has a bad pulsar coil, even though I put a new one it. I don't know.

Re: 98 ST350, not firing
The pulsar coil has an ohm value that can be found in the tech section. I don't think you will get a voltage reading here cuz all its seeing is a signal from the crank. It's got a magnet in it. Is the pulsar picking up the signal ( might be gapped to far )? Your coil, igniter, pulsar and all the associated wiring are your main components here. Grounds get looked over but are in my mind the most overlooked. Second, i've had bad parts out of the box. Test the pulsar by the ohm values. Use an ohm meter to check function as the flywheel notch passes the pulsar. Also, find that wiring diagram and check conn. to be in the appropriate place. Good Luck!
