    If you’re here with a new fuel pump and really low fuel pressure still check your grounds… Was just under my truck all weekend and it was just a crusty ground right at the firewall

      Power ground.
      The fuel pump needs two lines from the battery, positive 12V and the ground, which is 0V.

      That is a moment of discovery that is both irritating and deep relief. The same thing happened with my car, already known to have a persistent damp area at the front door hinge-- exactly where the fuel pump ground was found to join other device ground lines at a single, rusty screw.
      The repair was easy, at that point. After testing for recovered function of other, connected devices, I made sure the ground screw was cleaned, and ground connectors were soldered in-place

    Thanks! I was chasing parts on my Nissan Xterra. No mechanic could tell me what was wrong.
    But, you nailed it. Black sludge in the throttle body and coming out of the tailpipe.
    Problem with my Xterra is that they put the FPR in the worst spot.
    You have to pull the entire intake and supercharger off the engine to get to it.
    Ugh.

    Just replaced the fuel pump on 2001 Accord and still misfire p0300 p0301 p0302 p1399. Before i replaced the fuel pump i thought it needed the fuel filter replaced but it’s all in the gas tank. Wish I’d seen this video before i didn’t have to spend 3 hrs to work on fuel pump replacement ($26 delphi fuel pump not the whole fuel pump from Advance Auto $300+ ). Great video very clear explanation, great quality. Thanks a lot! Happy Thanksgiving 🦃🍁🍽

    Saw this on RUclips.
    Had issues with our 08 Avalon not starting, right away. Took several cranks before starting.
    Here is how I found it was a bad FPR .
    Turn your key...3x to the on position...but do not turn to start the car. What that does...it forces pressure to the fuel rail.
    After 3x, start the car. It should crank right away....mine did ...
    Changed the FPR ...problem solved !!!

    GREAT explanation! I am chasing fuel pump/regulator/fuel filter because my 2004 Toyota ACR30R feels fuel starved - typically drops out when under acceleration or higher revs. Actually, I can usually accelerate hard OK for the first 5 minutes, but after that I have to stay very light on the accelerator and lose speed up the hills in order to avoid misfiring and dying. Also when it dies completely, I just back off accelerator for a few seconds and then can drive (lightly) again. It doesn't completely stall even though and is an auto. I ordered an OBD, and have measured fuel pressure at 45psi, but didn't check this pressure when engine is off (like you show here). I have had spark plug coils fail before, but they were 1 cylinder at a time, not killing the whole engine, so this feels different.

    I had 5 leaking injectors of 6 in my 02 toen and country 3.3l was flooding. Replaced them ran well for 2 weeks now I get a crank no start as if I have no fuel. I did a toggle test where I key on off 5 times and it will start right away. If I do 4 cranks it will just about start and fail if I do just 3 or 2 or 1 it won't start at all. So leaning on loss of pressure versus totally dead pump. This vid has helped with my land rover. Now I need to figure how to do my van. As I don't know how to pull the regulator out.

    My 1990 f250 351w smells like gas just from cranking the engine. Hard to start. My oil smelled like gas bad and was very runny and over filled from gas being in it. New map, new tps, iac was cleaned and seems to be ok. I’m getting a code 31 with koeo test. Also get a 21,24,and 26 but I believe those are just testing out of range because the engine isn’t up to temp. I’m getting bad flooding obviously. Code 31 is egr sensor is below voltage. I have 5 v at harness coming from ecu. Sensor Olms are good. But that’s not the issue for the flooding I don’t think cause it doesn’t come into play until it’s up to operating temp. If. I put new plugs in it it starts and runs good but then I shut it down and the issue starts all over again. Exhaust is staining the ground like in this video. Also have a new coil. Cap rotor and plugs were new but plugs are fouled again soaked with gas. The little interference capacitor by the coil somehow has a melted harness. I’ve heard that those do more than just keep noise out of the radio. I’ve heard they can cause all kinds of issues. I don’t have a fuel pressure gauge so I haven’t tested the regulator. I’m thinking it’s either the regulator or a stuck or leaking injector. When I pull the plugs some are really wet and other are just black. Any ideas are welcome. It’s frustrating me. Oh and my egr tube is broken right where te ribbed part is. Could this be the cause? Idk cause of how the egr system works. Could it be causing hard start and flooding somehow. New o2 sensor also. There is so much gas getting through that when I changed my tps there was gas down in it

    Hi. Grateful for your video. So, I drive a BMW X3 2008 edition and it has its fuel pump system inside the tank. I recently tried to replace the fuel pump, but I had to remove the vacuum hose, other plugs etc. within the fuel system, to be able to access and replace the pump. In doing the replacement, I think I may have unplugged and left the vacuum hose sitting inside the fuel tank, which may have allowed some fuel to get in. And because I wasnt conscious at the time I was reassembling, I just plugged the vacuum hose back on the fuel system without trying to get the fuel that may have gotten in out (if it was even possible). My question is, could that cause the fuel regulator to become faulty and if it isnt faulty already, is there a way to get that fuel out of the vacuum hose if it not too late already? The reason is, my car has been having a long crank when starting cold or after it sits for about 20mins since that replacement. Thanks.

    • @PhillipsVision
      @PhillipsVision  Год назад

      First, you need to remove any fuel from the hose, then connect it properly. You may have to replace the regulator, but correct the hose issue first and see if that takes care of it before replacing the regulator

    Have a lot of symptoms you described. P0300 code on and off, slow crank no start intermittent runs great when it starts except times it has hesitation a bit when first driving but drives great within 10 minutes or so, checked pressure without truck being able to start just turned key and reading wasn’t where it should have to be and also it dropped slowly when connected. Just changed fuel pump, starter new spark plugs, wires ignition module currently has no codes, but we noticed fuel smell on dipstick. Is that a symptom? It’s a vortec 305, 1998 Chevrolet C1500. Do you think it’s the pressure regulator or maybe something else? Your video was very informative and thank you for that. Just getting frustrated with this crank no start intermittent problem. Appreciate any ideas. Thank you

    Hey nicely done video! I have a 1998 Nissan Pathfinder, 3.3L. There is a small 1/8 ID vacuum hose on rear of intake plenum that leads to fuel pressure regulator. It was disconnected for a long time unnoticed because it's hidden. I wasn't having any issue with it disconnected, and when it was reconnected it made no difference either. Do some vehicles just not utilize or notice a difference? No misfire codes or anything except EGR solenoid, which came back after I erased codes and with vacuum line attached, so nothing there.

    Hello,
    l have an 08 Lexus IS250. The car has a rough cold start, sometimes it doesn’t even fully turn on anymore. A couple of weeks ago, shooting some starter fluid in the intake will get it to start, but now it doesn’t. When cranking, it has 0 FRP(psi). As of right now, the car does not start. Does this mean the fuel pump is bad, or is it the regulator?
    Looking forward to your response!

    • @PhillipsVision
      @PhillipsVision  8 месяцев назад

      Could be the fuel pump if the pressure is bad. You can start with the regulator since it’s cheaper and see what happens. If you are able to check you pressure at the pump do that since that will pinpoint if the pump is the issue. Also test the pump relay, if that’s bad your pump won’t work.

      Some things I forgot to mention; before the rough
      start, my car died randomly while driving out my
      parking spot. The following day is when I noticed the
      hard start, and the stalling. Went to check for codes,
      and it had a pending code that had something to do
      with the MAF sensor. So I replaced it. And still had a
      rough start/no start. Had another mechanic check it
      out; he claimed it was the fuel injection cold start
      valve. We replaced that as well, and the same issue
      happened. Now mechanic states
      " We should verify
      it's
      1: spraying
      2: got pressure
      3:getting electrical signal.
      I did those tests with the old one, so I should've
      repeated them. Let's plan another trip and keep
      playing with it in the meantime. It's possible the
      check valve in the low pressure pump is leaking, or
      maybe not running at all, hence checking for
      pressure at cold start injector.

I had just replaced the EGR with a new unit, so the EGR code surprised me. Yet, as someone else explained, the EGR solenoid/valve is only part of the tubing, and the rest probably contains heavy carbon soot build-up. So, I face the deeper project of using an old speedometer cable, attached to a drill driver, to wipe the inside of the EGR tubing upstream of the EGR, itself. Then, clearing codes, and rescanning after a day or two of driving. As a "veteran" DIY, I am constantly learning.

Thank you in advance

    • @PhillipsVision
      @PhillipsVision  Год назад +1

      If your 5.3l is like mine, you should have a schrader valve underneath near the fuel filter (driver side). Get a reading of the pressure there. If that’s good it could be the pressure regulator, if it’s bad then it’s the fuel pump.

      @PhillipsVision hi man. I didn't find a valve closer to the fuel filter. But the day I checked the pressure and it was zero, I before that I replaced all 8 fuel injectors. So after couple day when I recheck the pressure from the rails it was almost 50. When I turned the car off after 10 20 minutes it gained closer 52. So I learned that the pressure built up over time when you replaced fuel injectors or something opening the fuel line. Amazing the fuel pump works. Thank you a lot for advice. You are cool
