Re: my merc has no fire HELP
First is to pull the plugs and check for spark. I assume you did that part.<br />Next would be to make sure the dead-man switch isn't tripped (if you have one).<br />Third thing to do is disconnect the black wire with the yellow stripe back by the ignition module. If you have spark now, then it's a harness/switch problem. If not, you'll need an ohmmeter and a manual to test components.
