Why did you put the Ph1 ECU in in the first place? Is the engine tuning over but not firing?
If it is turning over but not firing you need to check for spark and fuel getting into the cylinders as one of them must be missing if it won't start, or your not getting compression.
Really you need to put in some more details before we can tell you whats wrong.
ok i put a ph1 ecu in to sort out a imob problem and there is no spark atall ive cleaned all the point on it and still not workin so i guess i need a new one as ive been told.
