hi guys,

fitted an LT12 ECU, and just recently the car sometimes just wont start. It cranks and cranks with no sign of life. Then if its left for a night, it will often start up straight away the next morning!

Also i may have just been for a drive, so its all warmed up, then ill get back in and it wont start - i had success push starting it once or twice, even though the battery cranks the motor fine.

Now its just dead. I tried push starting it down my road, only to get it stuck at the bottom of the hill, and i had to tow the bastard back up.

battery is fine, just wont fire.

Thought plugs might have something to do with it, so i changed them, (needed doing anyway) but no result.

My dad reckons the injectors arent firing when the engine is cranking coz he cant smell petrol out the exhaust?

please help!!!!!!!!!!

Do you have an alarm, get that checked and make sure the cut is not on the fuel pump as i had an alarn that the imobisiser wouldnt turn off on.

Pull the fuel line off and see if there is fuel there when you are trying to start. If there is then it can only be the injectors or something stopping the spark.

well ive found the problem. The ECU. i pulled the microtech and plugged back the factory computer and it fired first pop.

bloody hell! not happy!

I want to put back my AFM so i can drive around, but it looks like some of the wires from the plug to the AFM have been bastardised by the microtech install. Anyone know the deal with this!?

:D :D :( :(

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
