I take it the fuel pump is working then. If not you need to check the 15 amp EFI fuse. It provides power to the ignition coil. The coils should have power to them all the time. The ECU grounds the coils as needed. There is a connector on the drivers side down by where the shift arm goes into the transmission. This is the connector for the CPS Crank Position Sensor. reseat that connector and see what happens.

ok I disconnected the cps and reseated no change. to check the fuel pump I disconnected the main line going it the injectors it has a green clip. I had fuel coming out when I turned the key on. But I think it should be under some pressure when then key was on it just flowed out. Like a garden hose with no end on it. It just ran out ?

It should have 40 PSI. If you have been cranking in the machine that battery may need charged. These machines are voltage sensitive. When cranking the engine monitor the battery voltage. Make sure the battery connections are clean and tight. Check the ground. Try jump starting and see what happens.

No snow here yet. Again try charging the battery or jump the battery to a good battery or vehicle. What happens is the battery may not have enough left for the ignition. Keep in mind that when you go to start the vehicle power is being consumed by the tail lights, brake lights, starter, fuel pump and what is left is for the ignition. Let me know.

You should hear the fuel inj pump running when the key is turned to the start position, with brake on. If it is turning over, just will not crank it is either no spark or no fuel. Charge battery, as NOOSV said and make sure exhaust isn't clogged up and fuel vent line isn't clogged. If it isn't doing anything, check brake switch and solenoid.

Start with the coil bolt. The mag is an alternator for charging your battery. Have you checked the spark plug wires? On the primary side of the coil you should have .4 OHMS between pins 1&2 and between pins 2&3. The spark plug wires should measure 2.3K OHMS. Again make sure the coil retaining bolt connection is clean and tighten. I would loosen it and retighten. Better yet remove and reinstall.
