Hi guys. Believe it or not, I have exactly.. I mean exactly the same problem. I also have a TTE compressor fitted. It started 4 weeks ago. Firstly when I stopped the engine, it wouldnt start again. it would fire then die, fire then die. Then 2 weeks ago it cut whilst driving twice. the engine just dies and coasts to a stop!
Same symptoms, it will fire and die, then it wont fire at all. After a few minutes it fires normally and off we go!! its been at Lexus for ages and they cant find anything wrong with it, but it has died while in their care a few times. No codes comes up when the ECU is tested.
I thought it was fuel, maybe pump or something, We dont think it is the piggyback ECU used, but Im open to suggestions!
Their at a loss, I'm at a loss!! Help is needed! for sure!!??
