So a month ago I discovered a strong smell of fuel in the cabin, did some research and discovered that the culprit most likely could either be a bad injector o ring or the fpd. At the time I also had a slightly hard start when the car was cold. So the car sits for a couple weeks while i work on it on my spare time.
Things i did while the car was down included:
-Banzai FPD delete
-Injector O-rings replaced
-Non -Sequential conversion
Now I put everything back together only to discover that my car was flooded. I then proceeded through every deflooding procedure i could find on the forums and the only one that worked was a tow start. I noticed LOTS of fuel dumping out of my exhaust pipe.
Finally i get the car to sputter to a start then die out because of a lack of fuel.
I fill the car and attempt to tow start it again only to notice the fuel flooded the car immediately as if the gas went straight into the engine. I had fuel leaking from around the turbo area as well as the exhaust, only underneath the car.
Now im back to square one with a severely flooded car and Im not sure where to start.
I applied a 9v batter to the injectors, and all clicked.
Im not sure if they are still stuck open causing the flood or the orings are the culprit, but could they (orings) flood the engine so quickly? Or maybe is it a combination of both? Any help would be appreciated thanks! Im pulling my hair out trying to get this thing started

 

When I swapped my Injectors I had a similar problem one of the injectors wasnt seated right I dont even remember what it was , But I took the upper intake manifold off and plugged the Fuel pump and you could see one of hte injectors jsut pouring fuel down the runner , So I took it apart made sure everything was ok , Used some grease ( old shade tree mechanic trick ) and seated everything again and .. its been running perfectly for months .

 

Pull the upper intake off. Jumper the fuel pump relay so the pump turns on when you turn the key to the accessory position. From there you will be able to identify leaks. When you put the injectors in, put a small dab of oil on the o-rings. Sometimes you have to seat injectors a few times to get them to seal right.

 

Yeah, most likely one or multiple injector O-ring didn't seal right.

 

thanks for the responses guys will take out the injectors and check on them once i get time
Also are the o rings suppose to be tough to put on the injectors? I almost had to stretch them a little bit to get them to slide up and onto the injector

 

One more question,
Do i need to remove the fuel rails as well or can i just pull out the injectors and save a bunch of time trying to get those fuel hoses off etc

 

Remove the fuel rail with the injectors still installed at first. Just unbolt them from the LIM and center irons. Leave all the lines hooked up and then jumper the fuel pump like noted above. If one of the injectors is leaking this will indentify which one it is. It should be an easy find.

 

what he said .

 

yes the o rings will be a slight squeeze to sit on the injectors. If you wriggle the rail as the injectors seat, you will almost feel them 'pop' into place. Also, white grease (vaso) is what i use at work for lubricating injector o rings. It sounds like you put the injectors in dry, which causes the rubber to grip on the cast seat lip and pinch the o-rings.

 

so
1. I found a primary injector had an o ring that wasnt sitting right. Fixed it
2. The secondaries were seated well but i noticed alot of fuel that they were drenched in when i pulled them out of the rail, is that normal?
3. I still cant start the car and I am getting massive puddles of gas dripping from near the oil pan, beneath the turbos... Idk where to go from here.
Is this still an injector problem or something worse?
As of now im debating if I should replace my secondaries or not to fix this problem

 

Sounds like an injector stuck open and fuel is coming out your exhaust ports.

 

So you didn't do what I said.......got it. Imagine that, just pulling the injectors out of the rail accomplished basically nothing.

 

actually i did what you suggested and thats how i found the primary was leaking, O ring wasnt seated properly, fixed it and im still not able to start the car

 

when you said fixed it. Did you replaced your primary?

If so, did you retest the system that DJseven mentioned by leaving the injectors on the rail and then priming the fuel system to see any other leakages maybe found?

I ran out of daylight so ill be continuing tomorrow morning, but just to clarify.
When I did unbolt the fuel rails and jumped the fuel pump, the injectors should not be leaking fuel at all correct? The only one leaking was one of the primaries which happened to have an oring that wasnt seated correctly.
But would the fuel dripping from the turbo manifold have anything to do with a leaking injector? It creates a puddle of fuel beneath the car within a few minutes.
Sorry for all the questions this is the first time Ive had to mess with the fuel system so im still learning

 

Did you perform a full Deflood procedure? Remove plugs, remove egi fuse, crank the car 5-6 times for 5-6 second intervals then install NEW plugs?
Wouldnt hurt to drop a cap full of oil into each primary intake runner on the LIM to help the engine build some compression as all oil will have been washed out from the housings.

 

^--- what he said X 2

Test the injectors , and bolt them onto the LIM , with a flashlight ( it was at night when I did it ) I flashed down the runners and primed the fuel system , tahts how I saw the leak , and after I fixed it I saw that it wasnt leaking anymore .


fuel generally only comes from the injectors (atleast directly into the engine )LOL kinda how things go so if you stopped the leak , and there is still fuel then you may just be flooded .|

I got my car started on the old plugs but I had to change them within a week . I'd check your plugs and go about keeping spares because at-least down here . I cant buy them from an auto parts store

 

So I found one of my primary injectors was gushing out fuel when i primed the fuel system, pulled it and found this small crack on the plastic piece near the end.
If i ordered an injector to replace it with would this piece be included?

 

It's a good time to send them out for cleaning, they'll come back with all new O-rings and caps.

 

you NEED to install the injectors and run the test with them in the rails before reassembling ****, thinking you fixed the problem when you didn't. maybe this time around you will listen to what was said near the top of the thread and double check your repairs.

now the engine is flooded and you are continuing to not check your work with a fuel washed engine that is going to be a bitch to start.

you can get replacement pintle caps but not all shops will replace them, ask the shop you plan to send them to if you do send them out. the pintle caps also cannot really get through the opening in the fuel rail, so i personally would not worry all that much about a slightly cracked cap. the caps are basically to keep carbon from fouling the injector opening in the intake, much like a spark plug collects carbon at its extremeties.
