I bought my 2000 4Runner used, and I can obviously see that the supercharger is installed. How can I tell if the URD fuel mod or 7th injector has been completed. If you have a pic of the location, that would be awesome.

Thanks,
Ben

 

um...floor it and listen for pinging?

 

Hey, you bought the green S/C'd runner from out of state huh? It doesn't necessarily ping if you don't have the urd. My guess, is take a look under the carpeting on either side of the console, and check for random wires throughout the engine bay. Or, net time you're in Denver/Boulder, we'll race...that should tell you right away!

There aren't any really obvious ways to see the URD kit. The injector splices are hidden by the S/C, and everything else is buried behind the dash, or in the gas tank.

The easiest way would be to remove the glove box and get to the ECU. If you see spliced wires leading from the harness you can bet their is some sort of FTC installed. If there are no splices, then you definietely don't have the URD.


Hope this helps.

 

This is by far the best way to tell, it only takes (2) philips head screws to pull the glove box, then slide the hetaing tube to one side andpull it out and the ECU is right there front and center. there should only be (1) wire going to each position of the plug if you see a bunch of spliced wires, follow them to the control unit and that's what you have.

By the way if you don't have it I would HIGHLY recommend some sort of fuel tunning modification.

 

ask the previous owner?

 

Thanks for the Glove Box tip, I'll check there.

 

1. See if there is a vacuum line going through the fire wall to the inside of the cab. The beginning of that line would likely be at the back of the blower. That line would attach to a URD FTC if you had one.

2. When you pull the glove box and the air duct just behind the glove box, find the ECU. If all the wires going to the ECU (the larger of 2 black boxes you may have) are black, then you have a TRD 7th injector setup.

3. Find the EGR port on the housing of the blower at the rear and just after the throttle body. If there is a fuel injector mounted in there with wires going to it----you have a TRD 7th injector.

4. If you have a whining noise coming from the area of the fuel tank especially if you have less than half a tank----you probably have a Walbro fuel pump.


Those are just a few things to check----
