My 1990 honda civic DX hatch has a fuel problem, i think?

you see, i had a puttering problem and recently the car just stopped working all together, i check many things, changed the fuel pump, the spark plugs, the wires, the fuel filter, and nothing, so i then pulled the fuel injectors, and tested them, they are working just fine, but it seems that gas may not be getting into the motor, i came to this conclusion by means of spraying some carb cleaner down the throttle body, and the car starts for a second...any ideas, id love some help on this one

maybe the main fuel relay has failed, can you hear the pump run? if not try replacing the relay and it should start. unless it is a timing or ignition problem...?

I would check for spark and fuel.. If there's no spark, then it's your dist. If it have no fuel then it's your main fuel relay.. Since you already change the fuel pump.. Disconnect the fuel line where it connectto the throttle body and crank the motor. see if there's any fuel come out.. Good Luck..

98 Camaro 3800 Fuel Delivery Problem...?

Ok, I have just asked a couple of questions regarding Fuel Pressure regulator and a Fuel Pressure Gauge, but now I'm just gonna lay out the whole problem right now.....



I'm having trouble with my fuel delivery system, it will run and drive for a while then it will die.



Here's an example of what's happening, the first time it happened, I was driving and I stopped at a red light then when I accelerated it died, So I had it towed home then tried changing the fuel filter and then it ran fine for about 50 miles (1 week later) no problems it happens again at a red light it just died and won't kick over so I have it towed home again. hour or so later after sitting it starts up again now I'm afraid to drive it because I know it will happen again...what could be the problem??



Injectors?

Fuel Pressure regulator?

Fuel Pump seems Fine because I can hear it come on when I turn the key.





I also hooked up a Fuel Pressure Regulator to the port on the fuel line and got this reading: 42 PSI with engine off and the needle goes down is that leak some where???



and about 45 PSI at idle.

First thing I would do, hook up an OBD2 scanner and check for codes. The second thing I would check is, fuel pressure regulator and fuel injectors.

It could be a transmission problem. That's if it is a Standard.

Fuel filter replcaement?

Hello all,

I am having a 1990,BMW 525i.Sometimes My Bimmer needs two or three cranks for starting.I have cleaned the fuel injectors with STP complete fuel cleaner and my sparkplugs are good.Do i need to change the fuel filter also?pls advice
Fuel filter replcaement?
A leaking fuel injector can cause this problem or a bad check valve in the fuel pump or faulty fuel pressure regulator. As fuel leaks pass the nozzle of a fuel injector it releases the static or holding pressure of the fuel system. Since the fuel pump relay is not energized until the computer %26quot;sees%26quot; ignition spark the engine has to be cranked first and then the fuel pump can then fill the system with fuel and pressurize the fuel. A leaking injector will also foul the spark plug or at least cause it to run rich. You will probably experiance rough idling after a long crank period if this is the case. A faulty pressure regulator or check valve in the fuel pump or external fuel leak will only cause long cranking times. A fuel pressure gauge installed between the fuel filtert and the injector rail will indicate wether or not the system is operating at nominal pressures. Shut the car off and observe the gauge it should hold pressure. If the pressure bleeds down you have a leak.

i would its cheap and you can do it your self. just remember safety, relive fuel system pressure and disconnect the negative battery cable.



let me know if you run into any problems
it may not do anything but it wont hurt anything either, its pretty cheap to do if you use pep boys. autozone. etc. for an after market filter
Oil filter should be changed with every oil change. The trouble sounds more like the alternator is acting up. Have the alternator checked.

My 1997 olds bravada won't start. The fuel pump does make sound when I turn the key.?

The fuel filter was changed, still nothing. It ran for a minute when gas was dumped into the fuel injector, but died shortly after. Any suggestions??? Thanks.........

Check the fuel pressure. You need about 60 # while the pump is runnung and engine is not.

Just because the pump makes noise doesn't mean it pumping at good pressure.
it'll run like poo if your not getting good fuel pressure sure but it will still start. it takes 3 things ti get an engine to start: fuel-air-fire, check to see if your getting any fuel to the rail by sticking a knife tip on the schrader valve (yours i believe has a green or black cap on a BLACK line) if no fuel is present check the flow on the fuel filter, you may have installed it backwords. good luck and god bless

What is the best fuel injector cleaner for a 3.1L V6 with 162,700 miles.?

I put in gunk high mileage fuel injector cleaner every time I change my oil. Is their any thing else out their that will work any better. Some one told me to use a product called Devcon ever heard of it?

From stush30



I purchase the Chevron Tech Ron, 4 bottles in the package from Costco for $10.00

sorry Rob if my engine had that many miles on it, it would need more than injector cleaners. How about a new vehicle?
if its a early 90s 3.1L V6, then the best kind would be diesel fuel (to blow it up because its crap). if its the newer style, i have no idea.
Well Rob, some believe that all fuel injector cleaner is the same. I work in an Auto Parts store in Baton Rouge and I have heard that one brand was better and another brand is better..... Sooo I guess I would base my decision on which brand I have sold the most of and the top two sellers are Lucas Fuel Injection Cleaner and Berrymen's B-12. The only thing I can think of that sounds close to the brand you refered to in your question is Chevron Delo. It also helps to add the injector cleaner to a low tank, therefore it is more concentrated. Don't run the car long with low fuel. Run about 5 hard, fast miles with low fuel and injector cleaner, then go fill up.
The best yet, BG 44 K If you can't find or get it try Chevron Techron.
Never heard of it. I would personally recommend using STP fuel treatment. Use that with Shell 93 Octane Premium fuel (V Power). That should clean out your fuel injectors really well
for starters, stay away from anything STP.

the best stuff is what works best for you.

Chevron Techron, it's expensive, but very high quality.

Seafoam

Prestone Synthetic injector cleaner/booster

Redline Fuel System Cleaner (my personal favorite)

Lucas fuel system cleaner (my 2nd choice).

and Synpower complete fuel system cleaner.
seefoam is what i would use
Amsoil Performance Improver

Hands down it's the Chevron Techron. I use nothing less then that. I use it every month, but use the cheap TEC walmart stuff (made by STP) every fill up.
Its a waste of money. Ethanol gas cleans injectors just as well .

Second Opinion, '93 Nissan Altima Fuel Injector?

Hello Friends,

I was having troubles with my engine flooding after I turned my car off, After checking the fuel pump and changing the fuel filter I decided to change the pressure regulator. While doing so I came across this little broken guy, http://i56.photobucket.com/albums/g179/M鈥?/a> .

My question is, could the (broken) injector have caused my engine to flood while turned off?

Thanks
Second Opinion, '93 Nissan Altima Fuel Injector?
It is a little difficult to tell if just the tip guard is broken away, or what? the best way to check for a leaking injector would be to monitor fuel pressure for a loss after shutdown. if you lose more that 5-8psi after shutdown, pull the injectors and look for wetting from the tips, The fuel pressure should stay around operating pressure for up to 30min after shut down. It may even climb slightly.
Second Opinion, '93 Nissan Altima Fuel Injector?
Absolutelly,if the injector was commanded to keep sending fuel it would flood out.
Yes, you found the problem. After the car is turned off the fuel rail still has pressure built up in it and what you have found is a massively leaking injector (which can flood and possibly hydro-lock the engine).
get a mechanic to look

How do you change the o rings in the fuel injector on a 97 Pontiac sunfire 2.2 liter?

This is simple on your engine ... go to your local auto parts store and purchase a Chilton's or Haynes manual for your vehicle it will explain how to remove the fuel injectors, relieve the fuel pressure etc. Once you get the injectors out the O rings slide on and off no big deal just time consuming ... two ring sizes and colors is most common!



In this picture you can see an injector and the rings ... http://www.billhughes.com/fuelRail.jpg
