i did my research but i just wanna make sure if its the tune..i installed turbonetics t3/t4, arp headstuds,cometic headgasket,walbro fuel pump, and rc 440 injectors now with my stock computer car will crank but wont start. and i have a gsr ecu with hondata s200 and when i use that with the stock injectors itll run but will turn off immediately unless i press on the gas firmly could this be another issue or is it because im untuned i seeen other peoples car run even though they were untuned and i need it running becasue my tuner said he wants the car running before he does his work. any help would be appreciated ive been nervous because of this lol

you cant put a honda dizzy in 180 out, they are keywayed. sounds to me like you need to go into the hondata settings and change your fuel injector setting to run the 440s like stock 240's and keep your foot out of boost until you get it tuned. The car is being flooded out by the bigger injectors and stock ecu combo. Also what Map sensor are you running? If you swapped it out for an aftermarket one, you need to change that setting as well

I'm pretty sure your not supposed to boost an untuned motor even if it can start. I believe the tuner does everything from one the car touches the dyno.

You should still be able to limp it to the tuner. His car wont even start up and idle.

OP, make sure you're the timing belt is on correctly. The camshaft arrows should line up on the head and the crank with the mark on the timing belt cover.

yea yhanks my guess is the timing belt a friend of mine just told me it sounds like its out of time..i must of put everything back on wrong. and yes im on a stock map sensor. but idk even with the stock ecu and stock injectors it wont turn over, before we took off the head it did so i guess it leads me to two possibilities either timing or distributor

if you have Hondata then you can get in there with a lap top. Download the newest version of your software from Hondata.com. Set you computer to your stock motor base map and upgrade injectors to 440c.c. and it should sit at idle nicely. I would Not think its your ditributor, dohc vtec distributors will only fit correctly one way, I'm not sure on LS. Also you will have to adjust screw on your throttlebody to raise or lower idle slightly.
