    Great video. I like how direct and informative it is. Also that you cover many possible problems and where to keep looking downstrem for the problem.

    Great vid ..... narrating instead of working at the same time makes a better instruction vid

    Good clear instructions. I have a D21 with a KA24E in it. I believe the psis are a bit lower, but the diagnostic points will be the same.

    My pressure is leaking at a medium pace.
    Besides checking spark plugs.........how can I test if its flowing back into the tank or a leaking fuel injector?

      You can remove the fuel rail with all injectors and hoses still attached if you're able to and turn on the fuel pump and look for any injectors leaking

      As far as it goes for the fuel pump itself, it would be safe to assume if your injectors are not leaking and you're having a hard time with the vehicle starting first thing in the morning is probably the fuel pump

    So what about if pressure is steady, but low? Filter has been replaced. I am supposed to see 38 w/ vacuum and 47 without. I get 21 with and 30 without. But it's rock-steady. Need to test if it drops under WOT jolts though

    Excellent, the only vid I can find testing pressure from the Schraeder fitting. I've found the said fitting but cant find an appropriate hose/connector. Your link doesn't work, and all the other kits don't have a fitting for the S fitting!! My engine starts well but fades out in seconds so presumably wiring is ok. Changed filter. Removed pump and while waiting for new one to come am practising putting it back in. But I would LOVE to test pressure before touching new pump. Another link maybe? Thank you again for the excellent vido!

    What if i move the key foward once, car off and psi doesnt move at all?? I crank it and it does movie to like 55 or so

  • @johncollins8304

    Also, my regulator is in the pump assembly but that is already out so can I test it? Since I've ordered the pump with basic carriage it doesn't have the lid with the regulator on it. Looks permanently fixed in there and I can't find it on autodoc so it may mean sending the bit I've bought back and ordering a whole bigger doodad -- but I'll only know this IF I can test it.
    Thanks for reading!

    • @backyardchevy328
      @backyardchevy328  2 ปีที่แล้ว +1

      thats the fuel pulsation damper, its absorbs any fuel pressure pulsation going into the fuel rail

      @@backyardchevy328could this also cause pressure issue my 98 camaro z28 takes a few cranks to start it feels good but once it warms up it idles rough and i cannot rev it sounds like it will bog out and back fire thru the intake sometimes

    I have a 2011 Avalanche LS 5.3, my fuel pressure gauge starts at 53psi the drops to 42 psi, I have replaced fuel pump, both knock sensors, map sensor, maf sensor, spark plugs, Catalytic converter is good, the strange thing is I do not get any codes. I am exhausted with trying to correct this issue with poor accelation, it started now a mont

      Do you have a vacuum leak or exhaust leak? that could cause the problem as well.

      You might be loosing ground voltage to the fuel pump

    • @backyardchevy328
      @backyardchevy328  2 ปีที่แล้ว

      Did u just replace the fuel pump and not the assembly? Because the fuel pressure regulator is part of the fuel pump module assembly
