First time starting car.. Nothing happens, pls advise

[sepulchralx]

hey guys, i tried turning car over for the first time, of course it doesnt start

The car is a 1996 auto 240sx, engine is an rb25det SII. I followed the rb lower harness prep writeup by alex cardio...

1. battery reads 13V2. as soon as batt is connected instrument cluster warning lights come on (similar to when you're cranking)3. relay clicks, nothing starts, fuel pump doesnt even come on4. i already jumped interlock (2 fat gauged wires)

pls somone give me suggestions

[kevwa]

you need to start with the basics - if your fuel pump isint coming on check to see why its not getting power etc...

was it even cranking?

[rob912]

If your fuel pump doesn't even come on it might be something in the wiring.and the connections to the fuel pump.

go back through your wiring and check it my 2 cents

[Darius]

And don't forget to check fuses

[SullivanRacing06]

fuses, gettin spark? and im guessin no fuel hu?

[sepulchralx]

Main IGN fuse was fine, other fuses were fine too.. I never wired clutch neutral saftey wire for ecu, but the rb25 ecu i have is for an auto..

[leesredgt]

Dont know if this has anything to do with it but it wouldnt be b/c of those to big blue relay's would it? were the ECU is at? I know thats why mine wouldnt start is b/c i didnt know i had to have those.

[sepulchralx]

i have those plugged in unless i wired the damn ecu relay wrong... which would be pretty hard to do.

[USMCgetsome]

hey bro just cause it's plugged in doesn't mean the relay is getting power. Look at the ign relay and eccs relay for power and check to see if the gates are closing. with the key in the on position

Do you remember when I was trying to track that gremlin down KUILLIN? It took me months and I still am not sure what caused it to finally fire over.

Yes definitely verify the power wiring at the ECCS and IGN relays. Start there at least.

Darius:

I redid my wiring, you were right the eccs relay wasnt getting power..

I unravelled every freaking thing heres what i found and then the results:

Findings:1. the ecu plug's eccs main power source to the relay was missing; the orange wire was actually in pin 17, and not 16, for some weird weird reason. I repinned that on the ecu plug to go to pin 16.

2. I went through all my wiring twice, looking at ecu plug diagram and the writeup for rb in s14.. everything was good.

Results:

Now when i hook battery up the cluster lights don't come on, so that problem is solved. when i turn the key the lights come on and nothing happens.. I hear the fuel pump priming now, and the power to the eccs relay is on good. I am getting power signal from F3 pin 1, ( ignition lead to injectors) and power from F3 plug 34, (start signal) and nothing happens. Its like the starter doesnt want to kick over or anything.

I've tried starting the car with clutch interlock jumped and unjumped. I believe that the fact that the start signal is travelling through the harnesses is a good sign.. it means i'm narrowing down my issues. I still have high voltage and my fuses are good... not sure about my relays... I dont know if the starter solenoid is even getting any signal. What should i look into next??

[kevwa]

you should check for power at the starter

[sepulchralx]

its not getting power i don't think because the starter works (i've jumped it before) so what would that indicate? where is the link between the chassis harness and the transmission harnss starter plugs? the fuse box? what are the key things i need to look at.

[USMCgetsome]

DORK!! theres a small jumper wire that runs from your ignition key all the way to the starter. I say just splice a wire and run it to the spade connector on the starter. Get on it and crank it up!!!!

[sepulchralx]

do you have a clue what color wire it is? is it orange, or grey/red? when i turn the key the orange wire and grey/red wire shows 12v, only when key is turned..

should i run a relay with that as signal or does it even matter?

[USMCgetsome]

no no no... Do this. Open up the steering column and access the ignition key switch. There is a plug that connects to the unit. When u find it look at the position for ign. Find the wire and splice into it and run that wire to starter spade connector.

Also, the starter is pretty easy to figure out. There is 1 wire that is for the start and is already connected. Then you'll find your 12volt wire from the battery system. The spade connector is where you need to send that wire from the ignition switch.

[sepulchralx]

I ran the signal start wire (when the key is turned to ign it gives 12v) to the spade connector on the starter solenoid... it shows 12V, and the main power source at the starter shows 12V as well...

Nothing happens when i turn the key at all. Is my starter solenoid bad? WTH?

I'm curious if i can utilize the SR solenoid on the rb starter i know the ka24de solenoid works... I searched on here and the whole starter is napa part # RAY2444514... I called NAPA and they said it would take an effin week for it to get here, and the price went up from 79$ to 90$... i hate napa. Thoughts?

whoa. I've never seen an rb starter go down. Wtf. If you want a replacement call up an engine importer like j-hot see what they quote ya. Also, remove the starter and crank it over again see if the starter will move at all.

also, welcome to the NRRBA! Get ready to spend some coin to get it running! But i'm glad your learning this way because now you know what it takes to be in this forum.

[USMCgetsome]

also, ensure you cleaned all contacts for corrosion and that the nuts are secured properly. Is your battery properly charged.
