RB25 NEO Staring Problem

[silvia of pty]

hi, I have a S13, with neo swap (550 top feed and greddy plenium), but I cant star the engine, I have chek every wire, I check the coil, ecu and cam sensor, in other car and work ok, I check and conect the neutral sensor. howeber I found the coil dont have the signal, so i dont have the spark. the fuel pump run , when the can is actived.
Anyone can help me with some advice? I need a extra Ecu???

Verify that you have a signal and continuity to coils. If not, check your wiring.

double check ur wiring.. are u getting fuel, can u hear t he injectors click?.. make sure ur cas is working that would cause u not to get fire nor fuel...

jesus christ bro those wires are scary, check cas, spark, fuel inj are clicky, you have a handful bro, lot of work going on there. but check basics and go from there

ok I tripple check the wires, I heard the injectors made the sound click, I check the signal and continuity to coils is ok, but the ECU dont sent the signal to the coils.

if its not firing it is a CAS related issue, regardless if the injectors are firing or not.

ok, for a review of the problems of my car, the coil have 3 wires
+ Pösite (ok, Good)
- Negative (ok Good)
Pulse of the 6 coil (I dont have this signal)

the light of check engine is on, and the car is star, but not run the engine.

I check the CAS in other car (skyline with same motor, Good)
I check the 6 coil in other car (good)
I check the ECU in ohter car (good)
thanks

it got to be in your wiring if everything else check up good.... make sure ur cas is wired right.. the wiring is a bit different for the neo than the r33 rb25....

Without posting any b.s. and to give you what you need.....

First Your coil powers need to be powered (they come off of the ecm ignition relay). If you have that relay wired correctly it also powers the cas and puts power to pins 67 and 72 so if you dont have power there then your relay wiring is jacked.

Next, verify if you have power to pin 24 which is the main injector power wire (should be hooked to ignition off of the switch).

Also make sure you have power at the following pins with the ignition on (80, 109) again if not then your ecm ignition relay wiring is bad.

Last make sure your grounds are good (ecm terminals 116, 124, 25, and 32) and (engine ground points). If all that is good you should have no issues.

If you have a check light and you are wired correct then please check your codes.

Your wiring looks like a mess and sometimes its best not to mess with something if you dont completely comprehend it.

If the harness was stock and you didnt cut anything that you shouldnt have, then it should be simple, else you have cut something related to the pins I mentioned and that is your issue.

I wish you the best of luck.

Lol.... Check your wiring..... Duh...
