So I might be joining the blown up 1J club.

[fstlane88]

So last night I doing a bit of street tuning trying to get my MBC dialed in and after one of the pulls the cars starts running super lean, and bogging sputtering, I'm thinking ok WTF, I pull over, pop the hood, and the #1 injector had popped out. It had happened once before but I was in a parking lot when it occurred and it hasn't done it since.

I start the car back up all seems normal. I start to head home and I decide to just see if it hurt anything, and to see if it's going to pop out again. I do a short quick 5-8lb hit and AFR's instantly go super rich. So I get out of it, and the WB stays reading rich until the motor shuts off. I coasted it onto the side of the road, popped the hood thinking maybe I had blown an IC pipe off, they're all fine, but that fucking injector had popped out again. I pop it back in and go to try and start the car and it won't crank, as in feels like something is keeping the motor from being able to turn over.

I called and talked to Jose last night about the whole situation while on the side of the road, and it sounds like the motor is hydrolocked due to fuel. The oil does have a fuel smell to it and during the first pull AFR's were in the 10.5 range, boost was around 10-11psi, and I was on a pump/100 mix. He mentioned it had happened to him to. And, that he was able to save the motor so I'm crossing my fingers.

I know it's my own fault, and definitely a lesson learned, just hoping I can save the motor.

how was the injector popping out? Weren't the hold down brackets bolted in?
Good luck man. Hopefully that engine is still good.

yeah he needs to invest in those OEM brakets that hold the injectors in place.

 

[fstlane88]

I know, I need them, and trust me I won't be boosting the motor again w/o them.

I had an injector pop out before. One bolt fell out of the bracket and boosting 18 psi it bent the bracket and pushed the injector out, was spraying fuel everywhere. I got lucky it didn't burn down the car. But didn't hydrolock.

Did the injector completly pop out? as in out of the rail and the fuel sprayed into the cyl locking it? or no? Running rich I dont see how it would hydrolock it. I had an injector stick open on me in my 7m, and it didn't even hydrolock the engine. (well I guess it did, I blew the HG cause of it), but didn't stop it from cranking even after a new HG (didn't know the injector died at the time).

ive got a spare set of em if ya want em

Sucks bro, hope everything turns out ok

 

[OneJSupra]

Yeah that sucks, you might still be able to save it.

Change the oil asap and crank the engine up couple of times with the EFI fuse and spark plugs removed to release all that fuel out of the engine. This happened to me due to bad ecu, injectors are stucked opened and kept dumping fuel and I thought the engine was f...d when it wouldn't start.

Good luck...

 

[Ric]

At least you still have the car and it didn't burn down.

 

[fstlane88]

I'll update when I get a chance to work on it wasn't able to today due to work. Luckily work is literally right across the street from me, so I walk to work anyway since it's pointless to drive. And, I personally don't think it hydrolocked but don't know what else would cause what it did.

Tissimo the #1 injector when it did pop loose, it wasn't out of the rail per say but it was out enough that the fuel in the rail would/could have easily dumped into the cylinder, especially with it occurring twice in short succession.

Bigzavs you got PM.

 

[JASONA70]

i hope you get this fixed right up and have no problems, it really sucks to not drive the supra :cry:

That happened to me too!

 

[tissimo]

lol odd, it was my #1 injector too, lol.. i think theres voodoo going on there..

Well find the witch doctor and get him to tell us what we did to piss him off!!! :icon_mad:

Slight update tonight, pulled the plugs and the #1 hole had a visible amount of gas resting on top of the piston. So, I figured I was going to try to see if I could siphon it out, but couldn't find the one I have already. So, headed out to harbor freight to buy another one...Between the time of me checking the plugs, getting the siphon, some oil & a filter, and getting home to pull the #1 plug again, the gas had I guess evaporated, or drained down to the pan???? Because I was looking at the piston top clear as day?!?!

Oil change and starting attempts tomorrow as my work schedule has me going in early tomorrow so I can't finish it up tonight. But, going in early means getting off with more day left to work on the car.

Thanks for all the support and good luck wishes guys.

 

[Bigzavs]

sent you a pm back

I was just about to say... Pull the plugs, gas evaporates very quickly. You should be fine.

:naughty: :love:

Did an oil change today along with new plugs and after cranking it till I saw oil pressure w/o the plugs....IT FIRED RIGHT UP!!!!!

Seems now that I guess I was a lot paranoid about something that wasn't really a big deal, but possibly could have been, and damn did it sound good to hear that motor fire up.

Thanks again for the advice and support.

I'm going to be oil priming my engine before I start it up for the first time, did you take out all the plugs then try to start it? Or did you disconnect anything else? thanks and glad to hear your supra is ok:icon_bigg

 

[fstlane88]

Yeah, pull all the plugs and the EFI fuse. Crank it in intervals of like 5-10sec. until you see it starting to build up oil pressure. Put everything back and fire it up.
