MR2 Gen 3 Turbo error code 12, oil/fuel out of turbo

Okay so I took my car for a quick drive around the block as its been having trouble starting. After sitting for a few days often if I go to start the car it make a horrible metallic clunk sound and the engine seizes. If I try turning the ignition it wont spin, like the engine is completely seized, then after a few minutes it will start spinning and fire up. The car smells rich on start up, very rich, so I figure I'm getting bore washing, where the car is running so rich the oil is getting washed off the cylinder walls. Thoughts?
 
Anyway I thought I'd take it for a drive to move some oil around the engine and bores. It was all running fine, then when boosting up a hill at around 7,000rpm in 2nd gear the engine completely shut off and the car rolled to a stop. I couldn't get the car to fire again, basically like it had no spark. the starter was spinning but not even a stutter. Anyway after some time rolling down the hill in neutral and trying to roll start the car, it started and I managed to get it home. I could not lift fully off the accelerator as the car would stall as soon as I lift.
 
So I look under the car and there is a mix of oil and petrol from the intake and intercooler sides, basically dripping down to the ground. I take off the intake and there is some oil/fuel on the air filter and a lot of oil/fuel on the intake side of the turbo and up the intake pipe. There is no oil/fuel on the catch can line going into the intake so I figure it is coming out of the turbo. Any idea on what's wrong?
 
I did a fault code check and I'm getting fault code 12 as well. Anyone know what this fault code is and what can cause it or had similar problems to this?
I've got a Gen 3 MR2 Turbo.
 
 
 
 
 

I was worried it might be a faulty ECU. I've got a Mines chipped ECU.
The car is always garaged. When it starts, it will fire on one cylinder, then after a little while pick up another cylinder and another till all are firing.
 
I had no engine lights come on, I just checked the fault codes. Yeah I was thinking I had an injector stuck open too or something but defintely not after the engine just cut out. Based on the fault code I reckon its one of these three things:
Coil is faulty
Ignitor Module is Faulty
ECU is faulty
 
The bad part in a way is the car starts now and runs. So the problem is intermitten. So the faulty ECU caused your overfuelling?

I spoke to a ECU exprt who fixes ECU's. He was saying he can check the ECU for me but really, really doubts the ECU is at fault. I've got to a do a few tests before giving it to him. He was saying to run the car with the MAP sensor disconnected and see if it overfuels on start up still. He also said to check the fuel pressure as I may have a block in the return line.
This doesn't explain why it cut out while driving through. That will have to be ECU, Ignitor or coil related.
What fuel pressure should I look for when I do my pressure test?

Also your engine won't run with the map sensor unplugged I'm pretty sure.
 
If you were going to do a pressure test I would be doing a compression test to see how healthy the engine is.

Try unplugging the O2 sensor and run without it for a while. You will get a fault code come up but the car will drive fine. It will just use default values for O2.
 
But if the wires are shorted than yeah it might think its running lean alll the time.

I had this exact same issue.

1. Check to see all cylinders are getting spark by removing the lead and putting a spare plug in and try cranking
2. Your plugs by now are rooted. Swap them out
3. Dump your catch can and clean it out as well as then hoses for where it got flooded
4. Check your relays and fuses in engine bay. I tested each one by one for open and close relay etc. Check the fuel pump or injector relay also.
5. The cranking surge thing is electrical. You tapped into a wire in engine bay could be that. Try adding earths from engine to chassis.
6. If you Did have spark and swapped the plugs and able to start it. Add engine flush but do not rev. Dump the oil and change filter.
7. Carby clean the throttle body after you added new oil and filter. Rev it and spray it.

That should help.

But the starting and power loss is electrical.

I wasted 6 days in a row and went back to basics then solved my own problem.

Okay if ur igniter is dead let me know. I have spare one as I did coil on plug so took mine out.

Did you try running it without the O2 sensor plugged in?
