i just got done instaling my turbo...t3/t04e .57 trim .63 ar...i have 550cc injectors right now i have a stock fuel pump in my 99 si and it wont start cranks and everything..could the stock fuel pump not be giving enough fuel and thats why its not starting???if so what size fuel pump would i need

 

you need a walbro 255 fuel pump atleast, HOWEVER the stock fuel pump would not cause your car to not start.

have you checked to see if it is getting fuel? is it getting spark?

 

what ems are you running? is it even setup for 550's?

 

ran same set up with no injectors untuned, ran fine except the car would take a **** after the beating, the walbro 255 installed ran a lot smoother.

 

well..i have obd2b to obd1 with hondata s200 and a p28 ecu that has a base map for 550cc injectors..however the p28 ecu isnt installed i still have the stock ecu in

 

so you have your stock ecu trying to controll 550cc injectors?

you just answered your own question

 

thanks...i didnt know...so it should run when i plug in the p28 ecu

 

if the basemap is good, then yes.

if it doesnt start then, put the stock injectors back in it with the stock ecu JUST FOR START UP.

before you do anything.....check to make sure the car is getting spark, and make sure it is getting fuel. any CEL's?

 

one code....IAT circuit high output
