EDIT 10/20/2008
starter has been replaced and car cranks now, just does not fire.
please proceed to page two for the latest on this situation.






ok so i have an s14 with an s14 sr.
i just put oil and coolant in it today with hopes of getting the thing to start up for the first time today.

so i pull the 7.5A fuse for the ecu from the engine bay fusebox.
as per heavy throttles instructions, i cranked for 20 seconds, hearing a kr kr kr kr kr kr noise, that really wasnt very pleasant. i stopped
tried again. oil light still on. i went inside, and left the key in the on position.
i may have been in the house for 20 minutes
i try again, and now i get nothing but a click noise.
this is a brand new battery, could it really be dead that quick?

did i do something wrong? i am extremely scared of this in the first place because this has been a damn two year project, and if something happened to the motor now...i may just take my own life.

please help me folks!

Mine just did the same thing.

Heres even a video of how mine was.

YouTube - KA24E Troubles (http://www.youtube.com/watch?v=3r71tYkMd1w)

I just re-charged the battery and it starts right up.

you did charge the battery before use, right?
devonkyle77
10-08-2008, 05:05 PM
yes
and i just put it back on after being on the trickle charger
still just does one "click" when i try to turn it over.
devonkyle77
10-08-2008, 08:29 PM
so i mean this thing is charged well enough after being on the trickle charger again and i get power throughout the car, but it wont even try to crank. just a click noise

noone has anything to add?

check your flywheel?? maybe missing teeth?? if you take off the starter you should see the flywheel.
devonkyle77
10-08-2008, 08:56 PM
i know the flywheel isnt missing teeth...

as for the starter, it couldve gone bad after the engine actually trying to crank the first 2 times?

devon. I will be over sometime to look at this. the charging system/battery doesn't have enough juice to jump the relay just click it. your starter is fine. I'll put money on it. yo battery is fucked. lower harness might have some faults also

like suggested have the starter checked out mine did something similar when it died. It took me so long to find a replacement starter that i use to have to push it hop in and pop the clutch and always try to park on a downward hill lol. trying to pop the clutch to start it while cold was a little more difficult i had to have someone push me with my other car to get it moving fast enough, yea i know sounds stupid but it was my first swap and i really wanted to drive it :)

Get a multimeter and check how many volts are on the battery. I had a similar issue occur with my SR and it was my battery that was low on voltage. Had about 10V I believe, but it wasn't enough to get it cranking.
devonkyle77
10-09-2008, 06:50 AM
it goes all over the place between 10 and 12.40 V

yeah you could have cooked it in 20 secs if it was on the way out. also could have drained the battery all the way to need a couple hours of charging.

Take them to make sure you didn't smoke them.

got a new battery. 12.70A constant

i put a wrench on the crank pulley and it turned easily, so my nightmare of it being seized has been relieved.
leads me to the starter.
i understand there is a way to test it using a wire on the positive terminal and touching somewhere on the starter? can anyone explain?
devonkyle77

here is a picture of the starter, if that helps anyone

It looks like the terminals on the starter arn't very tight.


But, I would take it off and take it to Napa or O'reillys and they will test for free.

Its not hard either. 2 bolts, a nut, and a plug.
devonkyle77
10-10-2008, 01:38 PM
took it to ASR today and they confirmed it was "bad"
they cant tell me more until they open it up, which should be wednesday they said.

in the meantime, is there another starter that works on s14 sr?
ch1873857
10-10-2008, 11:38 PM
yeah. a hill and a clutch.

you have to make sure there isn't something that fried it so it doesn't keep blowing your starters
devonkyle77

got the starter back today, put it on and now it cranks. although the car still wont start. i noticed one of the wires for my reverse position switch is broken, that cant possibly why can it?
aNskY
10-16-2008, 04:09 PM
more than likely the wiring is f'ed. this is a fresh swap right?

fuel lines correct?
devonkyle77
10-16-2008, 04:17 PM
yeah, fresh swap.
fuel lines are correct.
i primed oil pump, and now oil light goes out as soon as it starts to crank. which i would believe should be expected.
does fuel need to be primed also?
aNskY
10-16-2008, 04:28 PM
fuel pump should prime as soon as the ignition is "on". you should hear it clearly
devonkyle77
10-16-2008, 04:32 PM
oh ok. ugh, what the hell can this be?
96Turbo
10-16-2008, 05:01 PM
well now that it's cranking i guess the next step would be to check for fuel and spark

remove CAS, and turn it by hand while checking to see if you're getting spark (unplugged spark plug connected to the coil)

Then do the same for the injectors
devonkyle77
10-16-2008, 05:14 PM
remove cas completely or just unplug it?
96Turbo
10-16-2008, 05:25 PM
remove completely so you can turn the shaft by hand.(while still plugged in) This tricks the ecu into thinking the engine is turning to it tells the plugs and injectors to fire

edit: of course u should have the key on so the ecu/ignition system is powered up
devonkyle77
10-20-2008, 05:11 PM
ok not getting spark.....

10-20-2008, 05:14 PM
when my ca18 had starting issues...it was because of a bad battery ground check that
96Turbo
10-20-2008, 06:14 PM
just to make sure...you were grounding the body of the spark plug right?? (aligator clip from the washer on the plug to the head somewhere)

I had a similar problem when i swapped my RB. It turned out i didn't connect a wire that powers the ignition system. It wasn't on the ECU pinout so i missed it. Are you sure you're wiring is good?

Did you check fuel? Otherwise the ECU might not be getting power or somethin
devonkyle77
10-20-2008, 06:35 PM
i was told my multiple people just to make contact with the tip of the plug to the head.
96Turbo
10-20-2008, 07:01 PM
that works too....;)
devonkyle77
10-20-2008, 07:18 PM
i am very confident in the wiring btw, it was done by phase2. how do i confirm ecu is getting power? i assumed since windows and lights worked that ecu worked.

On s13 there is a ground at the back of the valve cover that is pretty well hidden between the head and the firewall. That's what prevented me from getting spark when I did my swap.
devonkyle77
10-20-2008, 07:29 PM
its part of the coilpack harness, right?
96Turbo
10-20-2008, 07:47 PM
basically, just ground the shit out of ur engine. Here's what i've got:

4 gauge ground from the block to frame rail

8 gauge ground from intake manifold to chassis

8 gauge ground from head (above exhaust manifold) to firewall


No problems for me. It seems like a lot of problems are caused just by grounding issues.
devonkyle77
10-20-2008, 08:15 PM
you seriously think its a grounding issue over ignitor?
alright, whatever. ill do it.
sbc
10-20-2008, 08:47 PM
Unless I missed it, you didnt confirm that you are getting fuel? As far as grounds there is...

the coil pack harness ground which I have grounded to the head
the ecu grounds to the back intake manifold (2 grounds right next to each other)
the ground that connects to the spade on the firewall
maf ground which isn't really relevant right now
the ground on the passenger shock tower ( i believe grounds the alternator?)
and one more ground that should be up by your abs which i cant think of now.

Adding more grounds cant hurt really so you might as well. If I'm forgetting any then someone chime in.

yes, i am getting fuel. furthermore, i know i have all those grounds except im not sure about the last two. i dont have abs though. and i know there is a ground on my intake manifold on the front as well, very large gauge wire.

when i was messing around with the ecu, i noticed a few things. in this first picture it looks like a relay is missing. or perhaps i have it plugged into the wrong place, because the empty spot looks just like the occupied spot. how do i know?
http://i84.photobucket.com/albums/k4/devonkyle77/SSPX0207.jpg

and this here, i found this plug just hanging out under my passenger side carpet. it looks like the harness goes to the back of the car running parallel to the door sill. it was not plugged in...i am concerned.

correction. not getting fuel. fuel pump is not priming
sbc
11-01-2008, 12:43 PM
If the fuel pump isnt priming make sure the big white plug (F4?) is properly plugged in with the clip in lock position. Its down there right by the firewall and the relays on the passenger side. It may seem snug but it MUST be locked.

Edit
If you need I'll try get pictures of mine down there. Its an s14sr in a 97 so it should help.
devonkyle77
11-01-2008, 02:18 PM
its locked.............
96Turbo
11-01-2008, 02:58 PM
use a test light and check the wire that goes back to the fuel pump at a few points. Start at the back by the pump, and if there's no voltage then work your way back towards the dash and maybe you'll find a problem with the connection, or wire, or somethin...

good luck!

so does that mean you're getting spark now?
devonkyle77
11-01-2008, 03:01 PM
no fuel or spark.
96Turbo
11-01-2008, 03:50 PM
is your ecu getting power? That's what it sounds like to me.

I don't know about as much about SR's...but see if there's an LED on the ECU or somethin to verify it's getting powered on. That would also explain no power to the fuel pump (as it's controlled through the ECU).

that's strange you're having these kind of problems with a professional wiring job...

Lets get a better picture of those 2 white plugs. I just took a look at mine and I definitely have 2 white plugs that are connected behind what I believe is the F4 plug. Also I do not have any empty relays. There should be 4 relays from what I remember.
96Turbo
11-01-2008, 05:24 PM
^agreed. I bet one of those empty relay holders is supposed to be powering your ECU

Im having the same problems.
Except I hear my fuel pump humming.
