360 will not start, any suggestions?

OK when you jumper the starter relay, you don't get full 12V to the coil for start. This is because the brown wire/ bypass circuit comes FROM the ign switch

So what you need to do in this case is get/ make up a nice big, long clip lead, and when checking spark, or trying to fire the engine, hook your jumper up from the battery (starter relay big stud) and to the coil + terminal. Don't leave this on there long than it takes to fire and start the engine.
