I have fuel coming out of the exhaust changed my fuel injectors. New fuel filter. No leaks on fuel rail or lines.

 

You're probably not completely burning the fuel. Either too much fuel supplied or it's not burning bc your spark plug(s) or coil pack(s) aren't doing their job. Your o2's are what measure the air/fuel mix

I once replaced my injectors with cheap Chinese and spent forever tearing apart and putting it back together chasing down o-ring leaks etc when one of the injectors had been faulty

 

The sparks and coils are also replaced they were the first thing I replaced when I started to have this problem. What about the fuel pressure regulator I also change one of the oxygen senor. When I got a code reading.

 

So, whether you have a leaking Fuel Injector or two or a faulty Coil Pack or two, the engine won't run smooth. However, even if the coil pack(s) are faulty, you usually don't get gas running out of the exhaust. The injectors supply an atomized spray and not huge amounts. But if your Injector popped its pintle cap, dumping is the outcome.

DO NOT DRIVE with this condition. a lot of unburned gasoline can damage the cylinders and more. Figure it out and fix it ASAP.

I'd put $$$ on the Fuel Injectors. Especially if your CEL insn't on with bad coil pack codes.

BTW, you used the proper NGK plugs? Right? Forget any other brand, including Bosch. Non Questionable fact that just is.

I can't find where you are or any mileage info, but the cars are old enough and higher mileage can easily be bad original Injectors. They eventually let go.

Thanks I give it a go around I let u know the out come.

 

Most likely when the fuel injectors went in, the rubber O-rings got displaced and let fuel blow right past them. Thy have to be lubed with oil before pushing them in or the O-ring moves.

Check that first. Hopefully, new O-rings were supplied with the new Injectors as well and grommets where the injectors seat.

 

Thanks I going to have to take everything off again and check the injectors o rings and the injectors I might of brought faulty one got them off ebay. And the car has high miles over 200,000.
Today got odg2 codes p1135 , po134 po300 . ?????

 

Went through the same thing... check out my thread on the P0300 Misfire. I replaced all 6 injectors, only to find they were all bad. Spray testing on a fuel injector machine is key to making sure they are spraying correctly. I also did drive the car a bit with stuck open injectors but not for long. Maybe 40-55 miles max in one trip with the CEL flashing due to getting it where I needed to get it to. No smoke was coming out at the time just a bit of misfire until 1 month later I started it up in the garage, the car smoked white from the exhaust with strong gas smell.. was running for at least a min or two to get a video shot then turned it off.

After that, I left the car for 5 months without starting until I got back to it and It still ended up being the injectors. There was a bit of fuel in the cylinders but was able to suck it all out. After new parts/fluids, the car runs fantastic and starts up normally. I thought the car was done due to stuck open injectors. I NEVER drove the car if there was white smoke coming out from the exhaust. Like I mentioned, I was driving it with flashing CEL that consisted of a bit of misfire at the time. I highly do not recommend driving it if there is white smoke coming out from the exhaust.

 

So if my injectors are good I could have fuel in my cylinder. Cause I havent been driving it at all but have been starting it up after I replaced parts. So how do I check if there is fuel in the cylinder?. Please let me know I about to give up on this car but I be done so much to it I dont want to. If u could help me out by letting me know it would be highly appreciated.

 

There is no reason to give up on your car.

200,000 miles in not all that high for this car.
Most of us have the same or higher mileage, and are enjoying our cars.

Sounds like you need to replace the O rings with new ones. Be sure to oil the O rings before you install them.
Failure to do so results in the problem you are having.

 

To get the fuel out of the cylinders either get a hose and insert it into the cylinder to drain it out, or turn over the engine with the spark plugs out and it'll shoot out the fuel. Just be prepare to make a mess if that's the case. Check the fuel filter too, check if your spark plugs are black. Black spark plugs means it ran too rich and need's replacing.

 

Wait, what do you mean you have fuel coming out of the exhaust? Like, doesn't every car does? When my fuel injector leaked, it flooded the cylinder so much that the car wouldn't even turn over. It just made one big combustion sound. Please give more details as to what you mean by fuel coming out the exhaust. When it's running? Cold start? When it's heated up? What exactly is happening and when?

 

Good points. I've seen people lose engines due to "hydro lock" that occurs from leaking injector o-rings. As soon as you think you might have a leaking injector, deal with it as soon as possible.

 

Drain your oil ... smells like fuel? ... probably does, right?

If so, you likely have a condition called "cylinder wash" or "fuel wash" due to failed injector(s) leaking fuel into a cylinder or two (even when the car is not running).

To prevent additional fuel seepage, relieve fuel pressure until you can fix your injector failure.

Also, while repairs are in process, pull your plugs to allow any accumulated fuel to evaporate.

Once the injectors are repaired or replaced and before you install new spark plugs, add about 10cc of motor oil, MMO (Marvel Mystery Oil) or trans fluid to each cylinder and then reinstall your plugs.

Before you re-establish fuel pressure, crank the engine 3 times ... no start.

Re-establish fuel pressure, start the car and let it run until everything smooths out.

Fix you injector problem.

 

ok let me start from ther begining my the check engine started flashing and the car started to run rough and it smell like gas real bad under the hood so i changed the sparks plug coils and fuel injectors now i have gas spitting out gas out if the tail pipe and code po300

 

Maybe one of your new injectors is bad ???

 

I would be looking for a wet sparkplug to locate the cylinder with the problem. To me, this looks like a pinched o-ring during installation. Be sure to use oil to lubricate new injector o-rings during installation.

 

So Tina, who is doing the actual work? You? Hubby, friend, or mechanic you paid?

If it's you, then we can guide you through. If it's someone else, that's different for many reasons. And if you paid for it, that mechanic owes you getting this RIGHT!

But whoever it is, I'll repeat the next step (as above): Remove each spark plug and see which is wet with gasoline. First and Foremost! If you're lucky, it will be from a cylinder (or two) on the side of the engine closest to the front of the car. You can fix the O-Rings easily without having to remove the top part of the engine. If it's the back side of the engine cylinders, that top needs to be removed and gasket most likely replaced. Fuel Injectors RARELY dump that much gas when new or rebuilt, UNLESS, the O-Ring got displaced when installing, or the pintle cap got knocked loose and came off after installation. Exceptions are very rare.

Talk to us. Spell out the whole story with DETAILS. It's frustrating asking for info and getting crumbs.

Have you checked your EGR? It might be clogged, so fuel doesn't get recirculated into the intake manifold and just exits thru the exhaust. How about your fuel pressure regulator?

 

P0300 is misfire. So, you either used bad spark plugs (only NGK is recommended) or bad coil packs (can't remember the two go to brands I think it's mistubishi or hanshin something like that and hitachi), if you got a good brand of injectors you're probably fine but I've had a dud China ebay one. Did the injectors seat ALL THE WAY and did you lube them before putting them in (could of ripped the oring) and screw them down with the little cap piece? Fuel rail needs to be torque specd with the all the little plastic washers, next to check is vacuum leaks and finally if all of the above checks out the only thing causing a misfire is probably the MAF. But the problem is probably with the injector install

 

Focus on Injectors, nothing else... I promise. I could of went and replace other parts when in reality it was defective new injectors. Still driving it today, and runs really well after a month of fixing it. Don't give up... I almost did too.

 

I'm not sure why folks just don't seem to want to acknowledge and pursue this.

I think this is the third or fourth similar situation in the last 6 months were folks keep looking for other sources of their classic injector failure symptoms.

 

Sadly a true story!!!!!!

 

As the other's have said. Fuel injector issues.

We definitly need to know if the injector O rings were oiled before assembly or not. This is critical information.

 

People dread doing the injectors. That's why they look for a different answer. It seems injector(s) are the obvious problem, but who wants to tear the manifolds off again. That's why I wouldn't use cheap injectors and concentrate on doing the reassemble properly. I have 168K on my engine and haven't had an injector problem yet... but when I do, I only want to do the job once.

 

I had my injectors professionally cleaned and rebuilt
when my car reached 180k miles. It's been 40k miles since then. No issues.

I realized that they would fail sooner or later.
I had another vehicle to drive while that was getting done.

I also cleaned out the egr system, replaced the hard to reach heater hoses, and all coolant hoses. I also replaced the fuel filter and all gasoline hoses. I should have also replaced the valve cover gaskets.
I know that my front vc gasket is leaking, perhaps the back one might be too. So I might need to remove the uim again. Darn....

I figured that a planned comprehensive repair was preferable compared to multiple unplanned breakdowns at inconvenient times.

Our cars are old. Our engine is a very good one.
But service is required after 20 years. It's time to accept that fact and deal with it. Once done, there is little need to do this again.

Wishfull thinking or half measures will not solve injector issues.
