Hey everybody, just so i don't get flamed i've searched for hours trying to find out the cause of my problem...and everything i've come up with ive checked.

I just got the swap in, i had a ka24e before...s13 sr, and car.

So, the motor cranks over, but it doesn't start.
It keeps blowing my 100A fuse for my battery relocation to...

I Checked the wires i soldered up in the bay for the main power plugs (where old battery was) and they all seem to be hooked up...

I am getting fuel (sprayed everywhere when i took off the line...)

I have 4 grounds excluding the one going from battery
If i mis-name them, please tell me the correct name...

1st ground.... going from intake manifold to chassy:

2nd ground....Going from lower wiring harness to chassy:

3rd ground.....going from coilpacks to back of the block (i think thats where it comes from):

4th ground....going from block to firewall (chassy):

Please help guys....this is sooo frustrating not being able to find the cause of my engine not starting....ive searched and haven't found anything other than what i've already tried..... are those the right grounds guys? any more needed?


Thanks!!!!!:newbie:

Do you have spark? Did you check fuel pressure?

I'll be checking spark again tomorrow...i did it today but i forgot to touch the plug on metal so i dont think it worked because of that...

I haven't checked fuel pressure, but when u take off the fuel lines it squirts everywhere?

I have the same problem -__- I'll be checking this often for updates haha. Just checked all my grounds today and they look all good so tomorrow i'll be checking if it has spark.

Spark and fuel pressure should be first think you guys check. And now you need a psi gauge to check it. Just cause fuel is there does not mean its good pressure

Will check those tomorrow, are my grounds correct? Thanks

Throw a multimeter on the coilpacks and check for 12v power, continuity between coilpack and ecu pinout for the trigger wire and lastly make sure the ground wire has continuity with the chassis. Multimeter is the shit. This is gains by the way haha

i'm not a big fan of having paint where you hook up grounds. might not have good ground connections because of it.

What's up Gains!


Checked all the grounds today with a multi meter, all reading same...good grounds

Got the problem sorted out though! It was a wire in my main harness. All is good now though.

Just gotta figure out why it fuel cuts right when boost starts to build (2.3k)

MAF issue? MAF fail safe kicks it around 2.5k.
