Does it turn over without jumping the starter relay? Clogged fuel injectors?

No it doesn't turn over at all using the switch only if you keep pushing it does but never long enough to start just a 1 sec then nothing battery is new good voltage , starter good new selinod still have to jump it and will not run at all only with starter fluid it will run

Sounds like a bad battery. Voltage could be great, but you have to load it to know for sure. Try a different battery. Some are bad right from the store. They may show good voltage, but not put out enough amps to turn over the engine.

Also check for loose or corroded connections. Check wires going to battery and in electrical box. Did you check the starter relay and fuses?

If you have a good battery, good relay, good starter, and good connections, and it still will not turn over, then you either have screwed up a piston/cylinder or have something stuck in the pump system.
