so my car ran okay today but now after i parked it i tried to start it up but it runs for like 5 to 10 seconds then shuts off. The only thing i really did was put in some fuel injector cleaner. could my fuel filter of plugged up and not allowing fuel to get to the engine. This filter was brand new but my car sat for 6 months so im sure there was junk in the fuel tank. So what im wondering is if i put in a new filter will it fix the problem or is there something else going on? i drove it to school one day, showed it off to my friends, and now it wont even run. im pretty mad and i want to figure this out quick.
