Hi!,, My 740 ti only starts with quick start,i spray alittle of it in the intake and she fires right up , after that it runs good , whent for 25 min hiway driving she is solid on acceleration and stady at idle , although it may stamble abit every now and then , but after all runs super.., let it cool for 15 min wonn't start again , so get my can of quick start and is all over again .
here is what i have done :
-check for spark got lost of it
-check for fuel presure got stady 42 psi (pump is good, so is regulator)
-check for in tank pump i can hear the buzzing
-replace fuel filter (old one was a bit plug up)
-after cranking for afew seconds lets say 30 sec. check if plugs are wet , but they aren't
_ i inserted a penut bulb in the electrical plug that plugs in the 1 injector and i can only see that the bulb only lites up very ,very weak , don't know if this is normal or my voltage to the injectors is not up to where it shoud be ...



please help ...
