Alternative For Expensive OEM Relays

Postby supra-raleigh » Fri Jan 10, 2020 2:35 pm

The starter relay, fuel pump relay, and EFI main relay are very expensive for the OEM replacements. Are there any equivalent aftermarket relays that are cheaper?

Also, did other Toyota cars use the same relays? I was able to use an ABS module from a Lexus on the All-trac and it was only $10 on ebay. It was the same part.

We can get part numbers and cross reference those part numbers to vehicles using them, if you tell us exactly what car you have. You didn't tell us that, and your user information lacks it also.

St185 fuel pump relay
28380-30010

I see some on ebay that say they came from an ls400. Toyota parts deal is only showing the st185 as having it.

Lexus parts now is showing only the 90-93 ls400 as having it.


Not sure about other relays yet.

So supra-raleigh is seeking the starter relay, fuel pump relay, and EFI relay for an ST185? How do you know that?

Just a guess. When someone asks a question here and doesnt say which car I just default to st185.

Chill out 93celicaconv, he's just asking for help. No need to bring the attitude.

And I would like to offer help. I just don't want to make assumptions that end up going in the wrong direction. No attitude in wanting to understand.

Starter Relay: 28300-10010: Used in 1987-1994 Tercel, 1992-1995 Paseo, 1990-1993 Celica (all models including ST, GT, GT-S & All-Trac

Fuel Pump Relay: 28380-30010: Used in 1990-1994 Lexus LS400 as P/N 28380-50010 California Spec, 1990-1993 Celica All-Trac only

EFI ECU Relay: 90987-02004: Used in 1980-1999 Tercel, 1992-1999 Paseo, 1984-1993 Corolla, 1985-1995 MR2, 1978-1993 Celica (all ST, GT, GT-S & All-Trac models), 1979-1981 Corona, 1983-1996 Camry, 1990-1991 Lexus ES250, 1992-1996 Lexus ES300, 1986-1998 Supra, 1978-1992 Cressida, 1992-1999 Lexus SC300/400, 1984-1989 Toyota Van, 1990-1997 Previa, 1979-1983 Toyota Pickup, 1984-1995 4Runner, 1989-2004 Hilux, 1990-current Land Cruiser

I would say salvage yards are full of starter relays and EFI ECU relays, but fuel pump relays will be a challenge.

The parts are for my 90 Celica All-Trac, ST185. As 93celicaconv pointed out, I neglected to mention that. For that, I apologize because he is right. Yes, I am assuming 93celicaconv is a he, just like Magroo made an educated guess that the issue was for an ST185....He he.

I must say this, 93celicaconv has gone above and beyond in that last post. That was the exact answer I was looking for and will be usefull for many others that use it to save some big bucks.
Thank you very much.

supra-raleigh, there are actually a few used Toyota OEM fuel pump relays under 28380-30010 on ebay, such as this example. May be worth finding out if Toyota still has this available, given it was also used for Lexus. But if one like this works, may not get a better price.

If relays cannot be found, cut the wires and install an regular automotiv relay. I did that with my car.
Fuel pump relay is bridged for 25 years now. Useless relay!

Very curious about this, do you know the part # and/or what Lexus it was from?

I think it was from an 92-95 ES300. It looks just like the one that came on my 90 All-Trac and has the same part number. I will try to get that number for a later post.

Hey guys, how about we keep this subject going and give some more alternatives for other parts that fit the ST185 that can be sourced from other Toyotas?

Now I'm really curious, because the Lexus one looks quite different. Photo for reference:
