Buzzing sound Passenger side, bad Ecu?

[boyee]

I have a problem starting my car... I changed the belts, turned it on and the check engine light turned on. It started fine, so i took it out for a spin, when i revved up to 3.5k-4k the engine felt like it choked so i turned it off and parked to the side. When I put the ignition to on, a buzzing sound turns on, located at the bottom right passenger side. I'm guessing it's the ecu? Also, the engine light isn't it. When I try to turn the car on, it just cranks. Please help...

Fuel pump, fuel filter, vacuum leak?

Thats your ECU telling you theres something seriously wrong with its circuit. Iv found from messing with mine, that if its not grounded correctly it will buzz. Or it will buzz if you have a short. However im not sure what else will make it do that. I would check the two main ground points on your engine block and make sure they are still good. One is near the firewall on the exhaust side. The other is directly above the coolant return from the block.

This problem could possibly be a nightmare to diagnose. I hope for your sake its something simple. Good luck man

ADDITION INFO!I checked under the hood and somewhere in my injectors it's also buzzing, so, both buzzing at the passenger panel and somewhere in the fuel injectors! Comments greatly appreciated!
