New injectors in. No start. I have d&d 4 into 2 so pipes are not near blocked. Going to sell as is Richmond, VA area

Nope. Trying 2nd set replacement injectors tonight and will post but I am not hopeful. Ran great as it was, replaced, cleaned whole fuel system including pump. These injectors are a last hope before sell as is.

Mine is still same. 1 reply cited he changed injectors and solved his. I already tried replacement injectors but same. I have a 3rd set (original, replacement, and replacements for the replacements that I'll do today and repost. I have no other ideas

No luck. New fuel pump, battery, 2 sets of fuel injectors but all of them have verified to work, 3 sets spark plugs, verified no leak in the vac lines involved, fuel tank has tank liner now after de-rusting it, verified the 2 tank hoses (back of tank) are open to allow air flow. Same as you...

I have been on the supplier side of automotive engineering and have seen this type thing happen all over manufactured parts. Remove a tab her, a grommet there, shorten the line by .05", and on and on in order to reduce the part cost. Although, without any further facts, if it were ME...I would...

I have the original which were in the bike when it ran great. I also have new injectors, not Amazon but not Dynatek etc. As a quality engineer, and seeing I can recreate the problem of no start by connecting the vac line to iaps sensor, it almost has to be a lack of vacuum; maybe from...

No codes... Just no start with iaps hose connected

Oh and no codes with or without iaps hose connected. Unconnected it just won't start. It will drive around this way but not running well

Thanks, I did replace injectors as the old ones were quite dirty and was worth it. poop carb cleaner thru them before install...

Sorry, "isps" should iaps, intake air pressure sensor screwed to back of airbox

I have an 04 busa that sat for over 2 years. Ran fine before. De-rusted the system, tank, etc. But now when I hook the center throttle body vac tube to the isps sensor the bike died at idle. I ran it without the iaps vacuum connected to the sensor and ran crappy, plugs all heavy black now. I...

Oh I did get a replacement IAPS BTW but still bike dies when connecting IAPS hose

Well I blocked the open hole under front of airbox and still same. Bike starts and runs but dies if I connect the IAPS (screwed to back of airbox Gen1 2004) to the hose that runs between throttle body 2 &3. All ways to airbox/vacuum are blocked. Bike will start only with IAPS hose disconected...

2004 busa also
