FUEL INJECTION PROBLEM

I have a Ford Ultima 2.9 12 valve V6 1995 and the right hand bank of injectors keep flooding pots 4, 5 and 6 with fuel and i mean flooding to the point of filling them up !!!!
With the fuel rail off and when i switch the ignition off injectors 4 5 and 6 just dump loads of fuel out. Then they seem to get hot and drain the battery dead...
This has really got people scratching their heads and have been no help to me...Can anyone please please help as i am desperate to get my car back on the road..
Thanks Steve...

The firing signal from the ECU is a grounding one so any short to ground on the loom wires controlling this bank will cause them to fire continuously.
Given all the bank are firing I'd suspect a loom fault so test for shorts to ground at the multiplug to the left of the engine looking forward. With them getting hot it's unlikely to be an injector fault, more likely to be a control circuit problem driving them full on.
