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 :( :(

      Boost cut after swap(RB25DET NEO) R34

      By Kinkstaah · Posted

      I used to have Walbro 255's when they were a pretty common update. (or were they 044? 040?) In any case I had a dirty tank. I thought the tank was good, but I would find the filter would clog in maybe ~50km of driving. If the issue persists, well, your fuel system or tank has crap in it that the pump is sucking up.

      Hi. Ok thanks for the info. I/we do not know what tune is on that Nistune ECU so it is why there is stock ECU and that Nistune is for later when the car is done. I have guy who tunes Nistune and other ECU so i will then take it to him to see and properly tune for the car   And for the update. On 99,9% it is bad fuel pump. Which is wierd cuz it is like 2 years old(brand new walbro 255) and that filter (also brand new) was dirty.  I was alwaya pumped premium(100) on very good petrol station so i dont know how is that possible...

      Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.

      So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here
