I've installed the URD 7th injector kit on my 2000 4runner and am happy with the results. I have noticed that the fuel pump continues to run after turning the engine off, sometimes for several minutes. It always stops on it's own, but the interval seems to vary. It doesn't seem to matter when it's a quick trip or a 45 minute drive across town. Is this normal?

 

fuel pump should not run when the truck is turned off. There must be something wrong with the Circuit Opening Relay. It gets a signal from the Maf to kick the relay on to run the pump. It may be correded and sticking.

 

I had it wired incorrectly. I emailed Gadget who knew immediately what the problem was. Two thumbs up for URD. Would not hesitate to spend more money there.
