P0049 code is not listed but P0449 is but it will not cause a no start. If it will run when injecting fuel or carb cleaner in the intake then the problem may be you're not getting. Fuel injector pulse, good you have power to the injectors but you need to check the grounding side with a niod light ($20 for a set) u plug 1 Injector and plug the night in re connector and crank the engine, it should flash if it doesn't, the problem will be a engine control module if you don't have any codes but you'll need a scanner to be sure. If it does flash you need to get a fuel sample and make sure it's good, if it is remove the spark plugs, let them dry and recheck everything. I hope this helps. Please give a positive rating. Thanks
