Need ECU (ECM) replacement for 1993 Supra 2JZGE

[A.BuckShort]

Non-turbo, auto trans., fed. emissions. OM PART # 89661-14580

Understand interchangeable with same configured 1992-95 Supras, 1992-05 Lexus 300s (and possibly Lexus 400s)? Is that correct? If so would the Lexus units have same OM part # 89661-14580?

Current core cannot be rebuilt because problem is fuel pump signal/circuitry issue. Have replaced fuel pump, fuel pump designated (smaller) ECU, cleaned throttle. Sent core to Philly for rebuild and return. Came back “ECU cannot be repaired.”

If all else fails have workaround option of running fused wire direct from ignition to fuel pump -- with current ECU also reinstalled (still seems to work for all other functions). But would prefer to first try to just replace this main ECU with a working unit including for fuel pump issue.

Seller offers, leads on available units, sellers, where to look also appreciated.
I really appreciate this forum. Thanks.
