1993 Sc400 Bad Fuel Pump Control Unit

[erniewilliams]

When replacing this unit, is there any particular calibration that needs to be done? It seems to be a pretty easy install. This is a part that sits on the drivers side back panel in 93 sc400. It seems that is a simple plug and play job but not really possitive about that. Lexus says that part is bad and wants to charge $400-500 to install. Part itself is $500.00 Hmmm...

I replaced this a year or so ago. I bought it new online at Park Plano Lexus in Texas for about $277 plus shipping. Just plug and play if in fact it is your problem. I had an intermittent start problem, and don't think it was my solution. But I left the new part in anyway. Do you want my old fuel control unit for $50 plus shipping? I can't promise it is any good, but like I said, I don't think it was my fix.

As of this morning. right after I did this post, I went to a alvage yard and found a unit. I plugged it in and the car ran for about 15 minutes, and then shut off. It will start, but will not stay on. I noticed that the unit was real hot. ? So maybe I do need a new one. Or maybe it is alternator or fuel pump?
