No dtc codes. I've shot directly into tb and also have shot into air cleaner. Both work equally as well.

unplugged TPS before cranking? a lot simpler advice than changing injectors! lol.

the tech bulletin that was mentioned had that as one of the steps in "L98: cranking, no start." a caution here, not to overlook that most of the data collection, test lights on, off, etc, has to be done with engine cranking.

also, the question was,not one cyl tries to fire? would indicate spark and some air/fuel mix.

it is in an old post here, will see if I can locate it and send to you.

Great thank you. Not one cyl. try's to fire until starter fluid, then fires right up.
