You sure it didn't hydrolock your engine from the fuel?

You are running aem right? V1?

I know couple of the V1s has that issue, i had one on my car and as soon as you turn the key ON it fills the cylinders with fuel.
I had to pull the plugs and crank the car over a couple time to get the fuel out of the cylinders.

Yes its the AEM V1

Thats what im hoping it is.. but sense I still have the NA intake plunem I have to pull that to get to the rest of the plugs.. So thats my task for tonight along with checking compression if I can get ahold of a tester from a freind.

Heres a pic of cylinder #1's spark plug... looks fine to me

For whats its worth, here's a pic of the final two guages mounted on the pillar. my SC **** pit as I like to call it. Ill get a better pic during the day to show you all the great detail of it all.. Dont mind the afr numbers motors flooded with fuel

Well the plug and SC cockpit looks great man. I want to see in the daylight.

Lets hope its the AEM V1 and not a blown HG. I think I would rather buy another management system than do the Blown HG. JMO. I am hoping once you pull the plugs and empty the fuel it will start up... without any smoke or excessive oil.

Yes your cylinders are full of gasoline so thats the reason why you can't turn it over by hand.

Its not a hg issues , pull the plugs cover the turbo and everything else and crank the car over the gas will come out and she will fire back up!!

I had this problem with mine, if everyone remembers. Mine actually caught fire, due to the excessive fuel went on the manifold wrap, and BAMMMMMM, had a fire... Keep an fire extinguisher handy just in case. Take it from me. Gas goes everywhere.... and I mean everywhere.. even with a rag placed over the cylinders.

I will be awaiting some pictures..

Oh yeah, due one cylinder at a time, not with three or four. That was my mistake. If it will turn over, then try two, then so on.

Alright fellas.... Looks like injectors #1 and #2 are stuck open. Left the key at on and I watched the cylinder full up fairly quick?!? Mad injectors?!

Still need to do a comp test to make sure the bottem end is ok cranks over just fine seems like but that's with all the plugs out.

Botton end should be fine, and i am sure you have enough oil in it otherwise your light would have came ON, You have a lexus lol not a Subaru where if you have 1quart of oil in the and the oil level won't even come ON haha I hate those thing.

I also have to agree with quick. Once you determine what and why the problem is, then change the oil.

Diffidently!! So glad that itís just a stuck injectors and not a HG even though now Iím contemplating on doing the TT HG and arp head studs ?!? What you guys think? Should take a full day for the job and Iíll feel safer getting into boost lol

Anyway anybody have any idea why those injectors got stuck? Like Omar said is it because of the AEM v1 or just bad injectors? If itís the V1 than Iíll have to start looking for the V2 to purchase and get some new injectors. FIC 650cc maybe to step it up or maybe just get the 900cc so I have them for my other motor when I do the swap. Any suggestions on the two?

Shouldn't have to do more mods it won't get rid of that problem. I remember when this happened to Omar he was not happy, it was definitely the v1. you can send it into them and they will repair the injector drivers that are shorted, or you can get another ecu to test.
It could be the injector signal wire got pinched or grounded out, or the injector failed open, but the chances of that happening to 2 cylinders at once is probably very small. Its more likely you burnt 2 injector drivers.

You maybe could use some spare drivers and reprogram the base cal, or rewire for batch fire and use half the drivers, but its really a huge hassle compared to just getting the ecu fixed.

If you are still on the bottom mark of the dipstick you are probably alright, some oil stays in all the turbo lines and stuff and can take a while to drain completely into the pan, I usually fill it a little past max because of that cause you have increased the amount of oil the motor uses at any given time.

Ok what I could try is swap the #2 injector plug to #3 injector and see if it will open #3.. That way I’ll know if it’s the AEM if that’s even a plausible test? If it’s most likely the AEM does that mean I need to replace those 2 injectors that are stuck open or once the ECU gets fixed or replaced it will close them?

Also for got to mention I unplugged the suspected open stuck injector and turned the key at on and it was still spraying fuel into the cylinder. NOt sure if thats noramal on a stuck injector but just wanted to through that in as well.

injectors are bad, if you can unplug them and they still spray.

Do this

move injector 1 and 2 to cylinder 3 and 4 then move injector 3 to cylinder one and 4 to cylinder #2

Try that , if you still hav ethe same issue have aem look at your box it's only $90 last time i checked and check you wiring harness.
