Thread: after swap issues!!

DE ecu, DE maf, DE injectors, DE o2 sensor?

Yah what injectors are you using with the DE MAF and DE ECU?

THANK YOU FOR REPLIES!!!
as of now i'm using de ecu, de maf, purple bb injectors, and the skinny o2 but it isn't connected, it started and ran choppy with the bb ecu, de maf, skinny 02 and purple injectors but from one night to the next wouldn't start... i put jdm distributor on with same part number as usdm and nothing... im a switch it back to bb ecu and try that then call it a night,... unless i get other ideas,... should i switch to usdm injectors? the 259? their red on my de... thanks

The u12 ecu prob has different pins than a usdm sr20de harness. If you have a sr20de usdm harness, a u12 ecu is probably different as well.

I know that with my w11 harness, a few sensors were different than a usdm motor. It probably came with an auto tps as well.

The motor can run with the wrong maf sensor (obd2 anyway) but it runs like shit. I forgot to buy an sr20 maf and was using one from a ga16 haha

so which ecu should i be using while trying to get it started?? and no the motor i got was standard actually.. the car has started and ran with jdm ecu, usdm maf, usdm distributor, and jdm everything else, but one night to the next decided not to... i switched to jdm distributro still same issue crank but no start...

a lot of people say the fule lines may be reversed but car drove like 7 miles like that so i don't think i have em reversed, ( fuel filter line runs to top of fpr) IIRC,

i'm still using stock fuel pump but i don't think that would be an issue to cause it to not start..

it just boggles me how one day it started and the next it doesn't....

do this. put in the 259cc injectors. unplug the fuel pump fuse. push the gas pedal down all the way and crank it untill it starts up. thats 91 usdm ecu/ de injects/de maf.

do you have a nissan data scan that you have plug up and see how all sensors are running?

gonna try that as soon as i get home to work on it..if rain lets up, and no no nissan data scan, ,i don't even have a fsm, my diagnostic knowledge is very limited lol

is that wrong?

ok so still no chance to change to usdm injectors and now batteries dead. so come sunday or monday going to get new battery check the jdm rail for leaks and switch it to usdm rail, with usdm ecu and maf, and try that... thanks for all replies again...

needless to say but just to remind you, do NOT boost the car while using the 259cc injectors
