Not sure what the heck to do here. I can get the car running but it just keeps dumping fuel out the pipe. After I shut it off, it floods badly and wont start. I crank it over and it just spits gas out the pipe again. If I let it sit overnight, It'll start up and run rough and spit fuel out again. Any ideas?

 

get new plugs and wires first. If that doesn't clear up the problem, get new ignition coils(they rarely go bad, but they are easy to replace). If neither of those resolve the problem, pull the injectors and either replace them or get them cleaned and flow tested.

Make sure you deflood the engine after replacing things, as well.

 

^^ That and check your fuel pressure too. The pump could be trying to drown the engine.

 

check compression b4u start buying things

 

ya dont just trow parts at it to try and fix the car. do some checks, cylinder leak test would be my 1st.

 

^^^^ Exactly. Now if only the FD had cylinders.

As for help: Dumping as much fuel as you claim, I don't think that the ignition is the culprit. That being said, check for spark on all of the plugs anyways.

I'd check compression first though.

If you haven't messed with anything lately, and you have full compression, I'm going to have to go with injector failure/sticking.

 

Damn, beat me to it...

 

Injector problems. The injector is nothing more than a fuel valve. To get that kind of fuel dumping into the engine, and injector is probably stuck wide open.

I'd cut right to the chase and get them removed for an ultrasonic cleaning and testing.

Obviously! I've had the car for 6 years and the engine has only a few thousand km on it. The compression is fine.

 

I think that's what it is. The compression is good as the engine is fairly new. The plugs were also replaced although now they may be fowled but I am getting spark and the car starts aftere sitting for a while but then floods and stalls. I had the 850cc primarys in it and opted to go back to the stock 550's. I swapped them out and things were fine for a while but now the car is flooding badly. possibly the injectors are bad? They were used but did not have many miles on them. I'm gonna go get some new ones and try those out. Thanks

 

Did you check the turn signal fluid?

 

If you notice his tag says "LS1 FD". So he does have cylinders on his car.

 

hahahaha!

 

i would also think injector problem.

 

Yeh, I know. But the OP doesn't....... so leak testing his cylinders isn't going to be much help.

 

I just reread and misread that your car is actually starting, my bad - anyway, I'll leave this here in case it's helpful to someone else...

I feel like I'm going back in time - this is the same problem I had on my FD 2 years ago - there is probably a post about it.

Got a brand new rebuilt engine from a well known builder(don't want to name names, because he is a good builder, everyone knows, etc.. and he did fix and warranty the engine for free).

Anyway, new engine, installed it, wouldn't start. Could smell the fuel - was definitely flooded. I did everything you could think of - pull plugs, replace plugs, WD40 in the engine, check wiring, recheck wiring, check for spark.

Last straw - Called a tow truck to pull me to the top of a big hill - roll start the bit*h, lol - nothing.

He brings the car back home, its tilted up, i walk around to the back, at least 1/2 gallon of fuel pouring out the tail pipe. WTF?

Damn, do I really need to do a compression check on a new engine?! I guess so...

Sure enough, no compression on the 2nd rotor housing.

Turns out there was a hairline crack under both spark plug holes in the housing.

Upon getting the new engine back, I promptly sold it, and went LS1 lol -

 

uhm excuse me but it's referred to as blinker fluid, and i honestly believe its his muffler bearing that has gone bad sooo

 

Dont be too sure about that, did it just happen after sitting for a while or did you drive it, park it and then it started doing it. I honestly would compression test it first. Then do new plugs, make sure to deflood it when you have the old plugs out and not installed the new ones yet. You can pretty much immediately foul plugs again if there is still a bunch of fuel sitting in the engine, and it will give the same symptoms you are describing. Fuel wont pour out the exhaust, but there will be some fuel getting shot out of the exhaust.

 

+1 on injectors.. something is stuck open and ur fuel pressure is just releasing out of the stuck injector when you shut the car off.

 

Had a similar with an FC, drove me nuts.
It had perfect compression and spark was fine. What was leaking were the coolant seals.
I'd pull the plugs and find them soaked. Initially I assumed it was fuel because that was what they smelled like. Turned out to be coolant AND fuel. The coolant would wet the plugs, prevent them from firing and naturally the fuel/antifreeze mix got blown out of the tailpipe. The smell of the fuel is so overwhelming you cannot detect the coolant.
Try disconnecting the fuel pump, either at the fuse or the wiring harness. Depressurize the fuel system. Pull the plugs and disable the ignition. Crank the engine with the plugs removed and it'll blow all the liquid out of the engine. When it stops spraying liquid out of the plug holes, reinstall the dried plugs and crank the engine with the ignition still dissabled.
Pull the plugs again and see if they are wet, If you notice they do not dry in a reasonable amount of time put a cigarette lighter to the electrodes. If you notice the liquid does not ignite, unfortunately you're probably dealing with coolant.
When I would reinstall dry plugs, similar to what happened to you, it would start and run progressively rougher until it died when the coolant refouled the plugs.
I never got the plumes of white smoke because it never ran long enough to get the exhaust hot enough to vaporize the coolant.
Good Luck

 

ya guys great.

My point is you check things out 1st throwing parts at a car is a waste of time and money when you don’t know what’s going on.

You can still perform a compression check will still give you some answers.

 

Its the injectors. If you just had them rebuilt its the o-rings on them. I had mine rebuilt at RC and they installed the wrong size o-ring so fuel just pored pasted them and filled up the housings.

 

im going with the injectors also, sounds like either the oring or stuck open.
