On my way to work today, my car was very hesitate under low throttle. I pulled over and popped the hood to see if a anything was disconnected, nothing. The car was turned off for about 2 minutes. I turned it back on and it as fine. Later in the day it happened again, this time I heard the fuel pump(Walbro 255 w/ HB Speed Housing) whinning a lot louder than normal. Again turned it off and let it sit for a couple minutes. Started it back up and it was fine for a couple miles until it happened again. The Walbro was whinning so loud I could hear it in the car with the windows up and music on. Anyone else have this problem. I think its the housing, its thick plastic. I ordered the MAPerformance Fuel Pump Kit w/ a new Walbro pump.

Again has anyone else have this problem or suggestions?

Check the fuel relay by switching it with the horn relay and it seemed to check out fine.
