Checked my ECU and it was fried on injectors. got a new ECU, had my chip swapped over but car is dumpin too much fuel. my fuel pump is on a switch and yes my fuel pump comes on when I hit the switch. but when I turn the pump on car wont start. when I turn the pump off car starts but runs rough. I have a SAFC2 that I have had with this engine for about 10 years. safc2 comes on but adjusting settings doesn't change how car runs if that makes any sense. I have no idea what to do!

1: remove the SAFC. Get a enthalpy or JWT ecu, tuned for your setup
2: check all grounds. Make sure you're getting good connection to bare metal, esp if you just painted the bay.
3: do you have a fuel pressure gauge to verify pressure at the rail?
4: pull the spark plugs, unplug the cas and fuel pump and injectors and let the engine dry out. i have a hunch the intake manifold is full of fuel or the cylinders have been washed down. have you changed the oil recently? did it come out stinking like gasoline?
