[fusbender]

I have a 02 wrx that won't start, i changed the fuel pump and it ran great for 2 days, now it won't start again, i can hear the fuelpump whir when i attempt start up so its getting power, any suggestions?

Does it crank? How old is the battery?

It cranks the battery is about 3 years old, i sprayed some throttle body cleaner into the air intake and the engine ran for a few seconds

Either you're not getting spark or you're not getting fuel. Given your statement above, I'd suspect fueling. Even so, spark is easy to check. When was the last time the spark plugs were replaced? What's the gap? If you replaced the fuel pump and it worked, there's likely something causing the fuel pump to burn. Did you replace the fuel pre-filter when replacing the fuel pump?
