How to Test Fuel Pressure (Chevy 2.2L)

[@veggiepowered]

I'am Your Newest Subscriber Great Videos . I Have A 95 S10 2.2 Liter With 5 Speed Manual Has Choptop Roof Hasent Ran In 11 Years I Wanta Get It Running Again Has Low Compression In A Few Cylinders

[@justinp8946]

Mine was staying at 61 psi while at idle running. I hope that is in spec? When I gave it some throttle, it didn’t go up. I guess that normal on these cause 61 psi should be plenty under load...

[@juntjoonunya9216]

0:26 no dude! I don't see any "cap" there... I'll find it tho

[@TheHortond]

Your regulator might be bad. It was twitching a little. When I tested mine it was steady as a rock. When I unplugged the regulator it would twitch like yours did.

[@brothercaptainmundo]

The fuel filter and fuel pump was changed. Still seems like the truck doesn’t have enough power. Going up hill in 5 gear, hits 55 mph. When I give it fuel with the hood up, sounds like it is sucking in a lot of air. Is that normal?

[@curiouscharacter1]

Gauge starts halfway between 40 and 60 and you're saying it's 55-ish? After turning the key off it's reading 48.

[@juntjoonunya9216]

What's that other green cap over to the right tho? Thanks!

[@AutOdometer]

I need to get one of these. Could you do a video of how to test compression?

[@MightyMechanic]

Yes I can. I'll do that video soon.

[@tinoy5360]

My son s10 2.2 pressure just drop did not hold planning to change injector and fuel regulator. Am I on the right track. It would have a hard time turn over. once it turned it rain good after few minutes off it would have a hard time to start and smoke black.

[@maryshan80]

My truck won't start 2.2 gmc 1998 Sonoma and with engine turning over read 35-39 psi could this be reason for no start cause it to weak? TKS FOR YOUR TIME

[@MightyMechanic]

That should be enough for it to, at the very least, try to start. I believe your problem is elsewhere. I would check to make sure you are getting spark and compression.

[@maryshan80]

@@MightyMechanic Checked spark and already put in new fuel pump still trys to start for a few seconds longest was like 12 seconds could it possibly be a jumped timing chain on this 2.2 gmc sonoma 1998, also replaced crank sensor and i believe its good since tach moves when it starts to fire a little also thought about camshaft sensor but leaniong toward timing chain skipped any thoughts would be greatly appreciated.

[@ccorrelllv]

@@maryshan80 probably definitely timing, timing chain tensioner usually breaks/loosens prior to chain failure, personal suggestion; don't bother changing crank sprocket. Not worth the headache

[@wintech5271]

please help, I changed the fuel pump on my 05 Dodge Durango and didn't bleed the fuel line. now I'm getting inaccurate gas reading. how to fix this please help might mechanic.

[@FA-sr6lx]

Hey I have 0PSI in my jeep but my car starts and sometimes I have to crank it longer to start. Could it be a bad fuel pump?

[@MightyMechanic]

Does it stay running after it starts? When it does start what is the pressure then?

[@FA-sr6lx]

MightyMechanic it stays running after I turn it on, never shuts off. But the pressure is 0. I think my pressure gauge is broken or a bad fuel pump. I'm going to test the fuel pressure gauge on a different vehicle.

[@MightyMechanic]

It can't run on 0 pressure. You must have a bad tester.

[@shanedidit]

Hello I have a 98 s10 2.2l and its saying 0psi on fuel rail sometimes it will go a couple psi but not much ,I can hear the fuel pump coming on is it possible its still bad even when it's coming on or could it be the regulator?, thx for video

[@cynthialozano6468]

I'm having the same problem does any one have any ideas which is it????

[@shanedidit]

@@cynthialozano6468 hello not sure if you have the same truck but I did replace the regulator and that was it hopefully this helps mine was clogged and was on the fuel rail

[@kevinvalenta8694]

Hey I have the same 2.2L S10 as you but I can’t seem to get my fuel pressure above 45PSI. Do you have a flex fuel model? I’ve replaced my pump, regulator, injectors, filter. Still 45 PSI. I’m at a wall on how to get my pressure up to where yours is.

[@juantellez7507]

Kevin Valenta where you find the pressure regulator; my is 2000 2.2 fuel flex?

[@Antonio-zn4ge]

I have 41 PSI at idle, mine is 1999 2.2L not fle fluel and yours?

[@JC-gv1zv]

Fuel regulator on flex fuel 2.2 is in the fuel filter

[@Hydemaintenanceman]

What if no valve?

[@jblue4786]

Is the fuel pressure cap always black?? I do no my Freon cap is green

[@MightyMechanic]

Most of the ones I've seen are black but not saying they always are. Just look and see if it's on the fuel system and if there are fuel lines going to it.

[@jblue4786]

MightyMechanic okay thanks brother

[@billmonroe8826]

Why is your motor running so rough?

[@MrDegger257FTW]

I just got a s10 it has a new fuel pump new filter and new injecteors... It idles fine if you barely give it gas it runs fine no problems.... But if I give anymore than half of the gas pedal it spits and sputters so bad the engine boggs and the best way ik to describe it the way it sounds is a 1990's honda civic with a fart can trying to do a 2 step.....if anyone may have an idea what it could be plz help I got it bc I thought it would be a simple and easy fix like spark plug or coil pack but they are fine.....

[@destructimus]

What if I have 90-100 psi while running?

[@tomrc4328]

If you have a SFI 2.2 S10 like shown in this video, then your fuel filter is probably bad. Three port filter has a pressure regulator. I had a brand new filter that had a bad regulator and I'd get 100 psi at idle. Put the original back in and pressure dropped to 55 psi at idle.

[@nvthisdw]

my s10 2.2 is getting fuel pressure and spark but is not starting. it will run on starter fluid. what do you think it could be. i cant figure out why the injectors are not pulsing

[@BradzBuildz]

Did you ever figure this problem out? I’m having the same issue.

[@jaywronker7636]

Try looking at spark issues

[@cindysinks5746]

Im getting fuel to fuel rail and pump is working but not getting fuel to fuel rail. Does anyone know what it could be?

[@INTERNA9]

Thanx

Fuel pump relay for a 2002 Chevrolet Cavalier

[@SaltySouthernOutdoors]

what is that hose/line that has a green cap? it's by the intake. thanks

[@MightyMechanic]

I believe that is the EVAP hose. The cap is where you apply pressure or vacuum to find a leak in the system.

Good, just tested my '02 Malibu with my new gauge.

[@scotthubeny1458]

I have 99 s10 2.2 liter with intermittent no start/long crank time to start, though sometimes starts right up. Suspecting fuel issue. Fuel pressure is about 40 with key on, and about 35-40 while engine running. When turn engine off gague shows it holds pressure. Is it possible weak fuel pump? Do you know fuel pressure specs for 99 2.2 liter engine. The fuel pump was replaced about a year ago, so I didn't suspect it, but now wondering since my pressure reading is at least 10psi less than yours

[@619russman]

Did you ever figure out your problem?

[@GiorgosC-rp5ms]

i have same issue

[@scotthubeny1458]

@@GiorgosC-rp5ms So I had my uncle who was a mechanic listen to it, and he told me it was the starter. He stated that the starter was sometimes catching and starts up, but sometimes not catching and thus the long crank/no start. I didn't really think it was the starter, but since he has decades of experience and as I had replaced the fuel pump last year and the fuel pressure seemed okay and it had the OEM starter in it from like 20 years ago, I decided to just go ahead and replace the starter. The result? Fixed the problem! Starts right up ever since, no issues! So, if you haven't replaced the starter in your truck, that could be the issue. I mean after 20 years, why not right? It's a pretty easy job to do, and the starter is not too expensive if you order it online.

[@DS-ss7vl]

What year is your truck???

[@MightyMechanic]

I believe this was an 02. They are the same from 98-04.

[@waynewoodrick5055]

just put a new fuel pump in wont start hooked up a pressure tester only goes to 5psi wont start

[@christophercassidy9962]

Clogged fuel filter

[@johnSmith-zr3en]

Why not show where the pressure gauge is connected😒 I want to know where it connects and I’m betting I’m not the only one...

[@tomrc4328]

Watch the video? LOL He pointed right at it. Unscrew the cap, screw the pressure tester on. How much more do you want?

Not applicable to 1997 2.2L

Where fuck is the connector??
