Okay so i have ek dx and i recently swapped in a gsr and its been hard to crank on on cold start. I'm thinking its due to the injectors. I'm using b16 injectors on dx harness. Anyone got ideas? Can't be the fuel pump either, cause i thought it was and got a wal. 255.

 

sounds like your fpr is losing pressure

try and turning the key off and on a few times to build the fuel pressure up

when the fuel pump came on wait for it to cut off then turn off key then turn it back on and do it about 2-3 times

and if that works change your fpr

note: all d-series and b-series fuel injectors are 240cc
