Re: no fire

Here is a link to the wiring diagrams, for older mercs.

I suspect something simple like the key, since it happened so quick. However some more info on what it does do, ie does it turn over, how fast, did you check for spark, etc etc.

thanks i will check the key. it turns over fine .after trying to start about four times and smelling gas from flooding it. took one wire off and checking for fire also took all plugs out and inspected them.
