check ecu fir meltdown?, the root of my problems began when i tried to start the car yesterday norning and it wouldnt go, after work i stuck leads on it and it did the same thing at this point accidentally left fuel pump running, i beleive by doing this i ruptured a seal somewhere so i assumed a injector after funding ports and cylinders filled with fuel, its on a emerald ecu,

if i disconnect the return line on bottom of regulator and run the pump only should fuel be pouring out of the return?

im hoping my regulato could be seized shut creating a high pressure in the rail causing the fuel to leak past injectors...?
