A few days ago I went out to start my beloved rav4 for work. It was hard starting, once it started it sputtered for about 20 seconds then died. It cranks over and gets gas. But to my avil, no start. I've tried many things after combing over several discussions and tried just about all I can think of. New spark plugs, checked the feul filter and pump, checked the coil packs. I'm at a total loss. It was about 15 degrees farenheit that day but has warmed since then. If anybody has had similar problems any advice will help.
