How to check fuel pressure??
Can someone help me and tell me how you go about checking the fuel pressure? I really need to check this to fix my car!! Let me know!
|
why do you think you need to test this to fix your car?
|
Because I need to figure out if it's my fuel pump/fuel lines, or my injectors.
|
fuel pressure gauge. I thought you already knew the fuel pressure?

Get a fuel pressure gauge and put it on the fuel rail |

If you test it again and its still low it wont be the injectors. They are the last spot the fuel goes thru. Get a fuel pressure gauge and put it on the fuel rail |
Did you find out what the PSI is suppose to be?

Jorge,
Did you only change the fuel pump? Did you backflush the main pressure line? If your pressure is low, I would suspect you can pinch the return line to check the pressure regulator. Also, when you pull the vacuum line from the regulator, if you find any fuel on that side of regulator, you are suffering from a torn diaphram. If your pressure is still low after changing the pump and blocking the regulator return, I would suspect clogged fuel line. I could suggest a couple of ways to clean out the sediment, but they all involve flushing the line with flammable liquids;-). Or a really long pipe cleaner. |
it says I need a special part (adapter) to check the pressure. Where can I get that??
|
anybody??
|
I have no idea? Search google maybe? it has to be out there.

Hello. I am having a problem with testing fuel pressure on my 03 tl. I also saw that i need a special adapter. I was wondering if you ever found the adapter or found another place to test and how?

You can buy the adapter for about $80. The part number is 07VAJ-0040100. I'm not sure if it fits any other fuel gauges, but the Acura fuel gauge part number is 07406-004000C for about $60. There's no other simple and easy solutions, so it might be easier to spend $140 than to hack something up.

Thanks for the reply. Im actually at a scrap yard right now about to pull the feed hose off of another TL. I'm just going to cut it and replace mine with it and use the fuel pressure gauge adapter that comes with most fuel pressure kits that you rent from auto parts stores that is a T fitting with the hose ports on it and use hose clamps.
Hi, I'm actually planning the same thing to read my fuel pressure. How did it work for you? Have any issues after cutting the feed line and using the standard T to connect your fuel pressure gauge? Did you fix our problem? |

Holy wall of text.
can you rephrase in sentences that normal humans can interpret so we can properly help diagnose your problem? |
You can thank Google speech keyboard 2001 3.2 crank no start except with starting fluid I replace fuel pump I'm wanting to know if my pressure regulator is bad it will start with starting fluid until it burns off my injectors are spraying 40 PSI so I heard would too much fuel cause these symptoms or does this mean I have not enough fuel if it could be too much fuel couldn't I hypothetically kink the line a little bit until it runs good until I could buy a new one basically what's most important is is this definitely my fuel pressure regulator I replace the sending unit the entire assembly it is spraying through my injectors which means it is spraying through my system as I've also physically checked I have not myself put a gauge on it one of the two failing mechanics told me they did and I like how you talk about my post being useless by making your post useless but nevertheless thanks for the useless reply and it's funny because I think anyone else can understand exactly what I'm saying without being the keyboard police

i think i saw useless in there a few times.. but i never said your reply was useless, i'm saying it's really hard to understand your problem and if you want some help, it'd be prudent of you to use commas, periods, and other types of punctuation so it doesn't look like you just had one stream of thought shat out in a single sentence.
But what do i know.. :io: |
Are you a bot?
Marc, we want to help you, but we need you to help us, help you. Did you get a copy of the service manual? you can find it on here for free by searching "1999-03 tl service manual." in the service manual they will guide you through the process of a 2G TL that doesn't start. since you are physically near the car I feel its best you go through this help diagnose what's going on. Here's a google search of some similar threads, maybe something here will sound familiar to what you are experiencing (a note of caution on replying to the existing threads as some may be over a decade old) https://www.google.com/search?q=site...hrome&ie=UTF-8 |
Here are a few ideas...
Any engine codes? How old is the gas in the tank? Maybe bad gas, water in the gas? Could be an issue with the gas pedal position sensor, it's on the throttle body. Could be the 'immobilizer' ie: blinking green light shaped like a key on the dash when cranking. You should also check the fuses and reseat all the relays in the fuse boxes. I think having too much fuel would not make it hard to start but just making it hard to keep running. I'm a curious out the loss of power you mentioned. I wonder if the exhaust pipe or the CAT might be constricting the exhaust. Btw, I don't think that would keep it from starting on it's own but would make it run like crap. Since the starting fluid makes the engine start briefly it sounds like it's not getting ANY fuel to start. Acuras (and hondas) famously have a main fuel relay under the dash that can develop bad solder joints and cause starting issues. Google "PGM-FI main relay - Honda/Acura" You might also check youtube videos like this one: Good luck |
I can't remember the codes but I think the exhaust was fine I think he check that. And I did see that component under the steering wheel I saw that video and checked in mine looks good I was just wondering if kinking my sending fuel line a little bit what kind of Mach a good fuel pressure regulator and give me a temporary fix but that would only be if a bad regulator would cause low fuel pressure and yes I agree that the starting fluid letting it start tells me I'm not getting fuel although my injectors are spraying I'm planning on checking it out tomorrow I also have to jump it because my spare key is stuck in my ignition at the on position such a headache but I'd much rather be driving that then walking I had a Geo tracker up until this point kind of embarrassing to drive it can't get no girls in a Geo tracker 4 any body that would have the balls to test that theory LOL I'll save you the trouble. So yeah I just signed up on here today got a hell of a welcome but it's cool to actually be a member here I must say I thought it would take months for people to reply this is awesome it's going to be like the world versus my Acura LOL hopefully we win I might just break down in order a fuel pressure regulator tonight I found one on eBay for $40 looks identical versus $113 at AutoZone fucking commies.....jk
