1JZ Hydro Lock

[zSP3CTERz]

So i was driving my nice 88 1j, doing about 45 just cruising when i hear a small back fire. Car seemed fine then when i went to hit the gas pedel it acts like its going to die. I knew somthing was wrong so i pushed the clutch in and began to coast off the side of the road. as i was coasting the car shut its self off. I tried to start it just once after i stopped and white smock blew out the tail pipe. didnt try again.

Had it towed to the mechanic the next morning and he tell me that 2 of the cylinders wre full of gas and that my oil had mixed with gas.

We drained out all the gas and it runs fine now. Anyone got any ideas as why it happend.

Well Id like to know as well.

You say it runs now tho?
WTF
Have you checked/changed the oil since?
Compression/leak down tests, coolant test?

This is just a guess, but I lost a 2jz-ge once to hydro lock because the 4th cylinder injector fired constantly and flooded it. The cause was a bad ECU. If your car doesn't have any fuel mods that could cause this, I would check the ECU first.

i also had an injector flood a cylinder full of gas. when i opened my ecu turned out the caps were leaky. driftmotion replaced them for me i havent had any more problems.

Fuel can only enter the CC via the injector. So thinking about it (and I'm no expert) either the injector go stuck open or the ECU had some sort of malfunction keeping the injector open.

Reading above, (and several other threads) what is most likely, something (like what homeskillet said) is wrong inside the ECU. Common problem with them is the leaky / bad caps in side of them. It wouldn't be a bad Idea to send it out to have it inspected and repaired (if needed) just to double check everything because of the common problems with the caps.

what a shitty way to loose a motor. A stock ecu takes dump...

Post the resoluton please, it will help others in the future...

I dont think its actuall killed the motor yet. at least it wasnt last time i talked to him.

Keith, call me and come get my ecu and see if it fixes it!

 

[Supra-Man18]

Im 100 % positive this is an ECU issue... I locked my 1j because of those crappy ecu's...

 

[zSP3CTERz]

yea motor still fine so far. getting ready to swap ecu's to see if thats the problem. then change out the injectors

Mine almost did the same thing. I had bad caps. Since the ECU is batch fire can you tell us which cylinders were full of fuel? More than most likely if they are in the same batch fire you have a cap issue within the ECU. Just take apart your ECU and look at the caps on the injector circuits.

 

[zSP3CTERz]

I did it in cylinders 3and 4 twice. and then in cylinder 3 and 5 the third time.

Did my ecu fix it?
