car is 89 crx si
b18a1 swap.

i bought my car with a switch for the radiatr fan, so i can turn it on manually.
but a year later i have grown annoyed of doing this.
what i want to do is wire the fan so it turns on by itself like it should do.

i have read that the radiator fan plug is on the back of the block.
i have found it but doesnt seem anything would plug into it.?.?. or does it?





i have always thought that the radiator fan switch was the green plug with the white and black wires.




can any 1 please help me wire my radiator fan correctly.

Aso i need confirmation that this code is for the fuel pump, and if so i can go out and buy one.

 

yes you have a code 43 for the fuel supply system. do you have any driveability issues as a result of this code, or have you noticed? try checking your fuel pressure. it could also be a clogged/dirty fuel filter or a malfunctioning injector.


In regards to the radiator fan situation, this is what you should see back there (the wires anyway, the block pictured has a fan switch located on the thermo housing)



The guy before you cut off those little plugs and connected the wires up to the connector which you see plugged in behind your engine. (notice how in my pic and your pic the wire colors are the same) That is an oil temp switch and in the teg is used to allow the radiator fan to run even after the cars engine is off. what you need to do is unplug that connector and move those wires over to the 2 pronged switch on the right. to test it, simply touch those 2 wires together and your fan should kick on. assuming your fan relay and everything else is in good working order then your fan should now work properly.

If you find that when putting the wires together the fan does not come on then test your radiator fan relay.



also, is their a reason why your oil pressure sending unit is not hooked up?

 

the connector at the top center in this picture is for the cooling fan switch - the one to the left of it is for the oil pressure sensor which is right below the cooling fan switch - the green connector on the B18 is the oil temp sensor



yes, that is a code 43, however, that doesn't necessarily mean you have a bad fuel pump

 

GL. I had the same issue and it's a horrible spot to get at. TY Honda haha
