5.0 TPI 5-speed ECM Help

Fellow members it has just been determined that the ECM on my 5.0 TPI 5-speed has gone haywire sending 6.0 volts to each injector and dumping massive amounts of fuel into the cylinders and oil. Car was never cranked in that state though. Dumped all the oil and will probably change a couple of more times. Does anyone know of a good supplier for Remanufactured ECMs? I don't guess new ones are available this many years later, but maybe so. Thank you.

Re: 5.0 TPI 5-speed ECM Help

TPI has power to the injectors (12 V) and the ECM grounds them to open.
You will have power on both wires at the injector if you were to check them. Double check your wiring is not shorted between the injector and the ECM.
