    My 4Runner last week was working just fine, able to crank and start up with not a problem. As of recently, it has become parked because it doesn't want to fire right up. It cranks, but fuel doesn't seem to be going through it. I have replaced from the fuel pump, filter, 3 relays that pertained to it, and still nothing! The Blue/orange wire that supplies power to the pump doesn't read anything, and checked all the wiring and everything seems fine. Can anyone help me out, this has become really fustrating.

    Does it have fuel? Don't trust the gauge
    Does it have air? Plugged air filter or ripped intake hose
    Does it have spark? Pull a spark plug wire and put a small bolt in it and place it near exhaust manifold to check for an arc when cranking. Beware of exposed fingers because it will zap you

    Everyone is fine and dandy. It gots lots of air, good intake hose, air filter clean and new as can be
    All spark plugs are good and spark fine. I did get a small shock out of it!
    And I got about a nearly full tank (Damn!) but when I hooked it up to a 12 volt table top tester on the ground and power leads of the pump itself, I can hear it whir, so the pump isn't out.

    I sprayed quite a bit of starter fluid in the throttle, and it turned over just fine, but died afterwards.
    That I did notice, which there is literally no pressure in the fuel rail, and taking off the fuel line before the fuel filter, I cranked over and nothing spurted out.
    That I know for sure, the pump is not getting any sort of power from the actual power line that comes from underneath the dash of the driver's side, from the relay, and to the pump itself; Although, just to make sure the wire wasn't faulty, I jumped it from the diagnostic box on the top intake manifold, to the positive terminal of the battery, and lo-and-behold; Power to the pump and it fires right up! Ran perfectly normal. So it makes me wonder if the wire itself is shorted somewhere in the cab or engine bay or maybe the wire is out of place and isn't getting anything in first place?

    We're having the same problem. Did you get it fixed?

    I have a 2020 TRD OR that cranks but won’t turnover. I just got a new key made and I’m wondering if it’s been programmed correctly.
