no it should not. Can you hear it running? Actaully I don't think I have ever actaully heard either my fj80 or fj62 pump run......now I gotta go listen for it!VA.CRUISER said:Can someone please tell me if the fuel pump on a '88 FJ62 should run constantly with the key on but the engine not running ?
Sounds like my fj55, the PO put an aftermarket fuel pump in, mounted on the frame, he wired it so that when the key is on but not running the pump always runs.....same as yours, I have been meaning to re-wire it right but.....ya know, just never got aroiund to itVA.CRUISER said:Thanks Texican and Landpimp for the replies.
I just bought this cruiser a week ago and it has done this from the beginning but it just didn't seem right for it to keep running I was comparing it to my '97 Chevy Truck like Texican said it turns off after a few seconds. The pump sound is loud enough to hear with it running (no radio)yet.
Thanks Again this is going to be my DD
No no no. There is NO pressure switch in the AISIN (Toyota) EFI system for the fuel pump. You are thinking of the Bosche setup and similar. My VWs could "prime" the injectors by turning the key to "Run", wait a few seconds, and you'd hear the fuel pump run then quit. Then hit the starter and they'd start right up. But the earlier Toyota EFI system doesn't work this way.smtyblt said:just like what was said earlier the pump is controlled by a pressure switch and when the pressure cant be kept up the pump continually runs
