Make sure battery has a full charge and battery connections good. Also check your charging system. Use a digital multimeter for testing, so you can see actual voltage. If battery is down, use a charger and get it charged up. How long since a tune-up? Any applicable trouble codes? At the ignition coil and fuel injector, dark green wire with orange tracer, should be hot, engine cranking. Is it? You can use a test light on that wire.
