S13 SR, finaly! :) but still some problems...

[superman29]

I already post in technical forum but much people come here

So i'm just trying to star my sr, the engine crank, the fuel pump work, but got no spark and ingector pulse... The ecu send me a code 11 ( CAS) when i try to start the engine... but i chek the my wiring many times and chek the CAS as its tell in the FSM and every things ok i've also try another CAS and same thing. ground is good.
i'm wondering if there are relays for the ignion and injection??
Or can it be a bad ECU??

Any help will be apreciate thanks

recheck wiring located by Battery tray, brown and grey connectors,check all fuses,sounds to me like your not even powering up ECU.

[superman29]

yes the ecu got power... but i wil chek the fuse today

I had the exact same problem and it ended up being my engine conrol fuse. My turbo timer and alarm were both wired into the same ignition wire and it was drawing too much power. Everytime I turned on the ignition, the fuse would blow. Check it out hope this helps

[superman29]

I just chek and all fuse are fine... I will try another ECU tomorow

[liquid_cool]

the only thing i can think this problem wouldcome from is the crank angle sensor..that controlls the information that goes to the ecu and tells injectors to fire and your spark...hope this helps...on the ka24de the cas is located in the dizzy..i believe yours is somewhere on your housing by the flyweel.

I think i have the wrong ECU...
on the one that the guy sell me with the sr20 there is no stiker that say which ecu it is and the sticker at the screw is in english.
But on the one of my friend this sticker is writer in japanese, is it always in japanese???

I can't wait until tomorrow to try it!!

F*ck yeah! i got fire and fuel!!! ....... But... it don't start, i got only back fire....
any idea????

check your timing

check your timing

Timing is off, pull the cas, set it to tdc on the compression stroke(#1 cam lobes facing away from each other), reinstall the cas according to the fsm, then put a timing light on it and set the timing to 15* btdc.

I set the CAS today, i also had a code 21 today, after long search i finaly succed to clear it. Now i got code 55 like supose to. i finaly get it started but after like 5sec. it stop... I will put a timming light on tomorrow, i hope it will work!

[superman29]

finaly it did start today! i think it was because of the oil that the guy before put on piston before store it that i got difficulties to get it started at the end because the timing was good.

But there still some problems... I got a oil and a water leak that i will fix tomorrow.
But thats not all... the engine don<t run pretty smounth on idlee.. it seem to run on 3... i check compression and i got 150 on the three first and 140 on the last, it looks ok to me... and the ecu is giving me a code 21. this code is for main ignition signal i check all the wiring and its fine. Can it be the ignitor chip that cause that?

I try to test it like it's said in the FSM, i got continuity where supose to but the resistance is high and not constant...
