hao, tai hao le. i didn't realize the oil pressure switch would be the culprit. it is proven that the oil pressure switch is partially short to ground. the fuel pump power is felt by the fuse, the fuel pump relay pin 30 to 87, the oil pressure switch (this feels battery power to fuel pump, parallel with the pin 30 to 87, when oil pressure sets up, the switch turns on, no pressure it is off). you can check the switch by pull out the fuel pump relay when the engine running, if the engine shuts off, the switch power feeling line has trouble, if engine keeps running, the switch is OK. It is hard to believe the switch failure to burn the fuse. Thanks for your useful information.
