s13 electrical problem

[Linux2501]

Alright I rebuilt my ka24de s13 and took the dash out and engine out along with the engine harness only. since I put the engine and harness back in I have been having trouble after trouble. well one i believe my ignition switch is shot, the oil light and the safety belt light is on with the key out. second problem is the starter relay not sure about a couple of the plugs some be swapped. but when i turn my key i get a click when I turn it but its inside the cabin. now im getting fuel to the rail and i wanted to know which ones is the return and the inlet top is where i have my pressure going to. and as for the starter 12v signal wire there are two yellow and black wires, is it the heavier guage wire? also my flip up lights are stuck up. Help I am a newb with this chasis, :newbie:

THe return fuel lines would be from the top and bottom incoming.. What do you meant heavier gauge wire? IF you flip light are stuck up then you probably have bad motor, fuse, relay or it not getting power..

[Linux2501]

AS a heavier guage wire as in thicker with a black and yellow stripe what color wires go into the starter relay?

[kennedy8383]

IT look like 8 gauge to me not 10 gauge..

[Linux2501]

What would be the possibility of the wrong wire going to the signal cable and how would I know if my starter relay is bad?

[kennedy8383]

IF you don't hear the relay clicking not it meant it not working or you can try testing them but you will have to google how-tos on that.. Are you tryng to connec the yellow and black wire or something to the relay??

[Linux2501]

No I'm trying to trace down a problem there is the starter relay that's blue under the fender I'm trying to figure out where everything goes and if its bad and so on

[JDMRIDDAZ]

if ur dash lights r on w key out the u have bad battery terminals
replaced them at once if there done the u have a bad ground to battery or to chassis

[Linux2501]

I've checked them any other suggestions? But its every now and then

You might have forget to connect a wiring some where under the dash or engine bay or you might have connected wiring wrog. Have you try checking to see if the starter connected correctly. CHeck those carefully and ground wire. If you hear click while turning the engine then check the ignition wiring properly and check to see if the clutch pedal switch are o.k

[Linux2501]

Alright Its and auto, the trans is hooked up to the correct wires, and I arced the alternator wire to the frame I have my ground to the engine and the frame, how can I check that starter relay under the fender by the battery and is there a ground on the starter and also is there a way to find out what wires come out of the relay box,?

[kennedy8383]

Yes i think there a ground for the starter relay right by starter.. The fuse box that beside the battery didn't mention about the starter relal. I thnk there an interlock relay beside the battery and might be for the auto tranmission for 240sx and sometime goes bad.. Maybe if google it up it might help. THe fuse box beside the battery contain fuel pump green , headlamp gray , and condenser fan relay blue, and e.c.c.s relay green.

[Linux2501]

Alright so on a side not what all do I need (bare minimum) for the engine bay I've taken the blower and the heater core off. What all do I not need? Sorry for all the questions I'm new to these cars.

[kennedy8383]

THe right side fuse box contain

accessory relay 2 - blue
inhibitor relay a/t medel with a.s.c.d black
clutch relay m/t with super hicas black
a/c relay blue

4 other relay are headlamp relay and horn relay but i didn't think those are important..

[kennedy8383]

THere nothing wrong taken the blower out but you need to keep the heater core that connect to the fire wall to the engine behind..

[Linux2501]

May I ask why?

[kennedy8383]

I have taken my blower out to tuck my brake line and weight but the heater core need to be there because there coolant that goes in there to the engine..

[Linux2501]

I did the procedure I did with my 3000gt and removed the AC pump lines, cooler and everything else. And route the lines coming from the core and recirculate it,

[kennedy8383]

Everything can be remove for the a/c but not the heater core behind the firewall..

[Linux2501]

Well damn, I'm not near my car atm but isn't that he box with the two aluminum threaded fittings on it?

[kennedy8383]

Those 2 fitting goes to the engine with the hoses.. I thought you have electrical problem now coolant??

[Linux2501]

It is an electial problem because I cannot get this car to start and a result of me stripping the car of uneeded weight I took out the blower and core and other items

[JDMRIDDAZ]

jump starter to see if it turns over then back track from there

[Linux2501]

Starter is good and I'm trying to find out how to test that blue Box with two connections going to it? And is there a ground physically on the starter

[JDMRIDDAZ]

ok cut the dum blue relay out and connect the 2 heavy gauge wire together
wheres the battery?
front or rear
if in rear do have a ground running from batt ground to engine
i ve fixed this problem on mad ppl 240sx...
also does car have an alarm

[Linux2501]

No alarm and its in the front of the car

[Linux2501]

Also how do u make a kaa20det?

[Linux2501]

Alright my s13 dohc auto will not start im trying to trace things down but sadly im having to test everything by myself. but anyway on the fsm it says white/ b/w and on e 12 it says b/w and b/y and im not sure exactly yes i know it means black and white and black and yellow but on the starter relay im confused on if it has the right wires going to it. here are the images. also im wanting to make sure this is the right wire going to the starter 12v signal wi

[kennedy8383]

Do you have DMM. Get it and test it and see the relay getting voltage. DId the car work before when you pull everythings out? You might have forget to connect something somewhere...

[Linux2501]

It ran before I threw a rode through the block

[Linux2501]

This is the image of the starter relay is it the right wires?

[1fastser]

well one i believe my ignition switch is shot, the oil light and the safety belt light is on with the key out.

^have you checked the switch? When my starter relay went out I bought one from VatoZone for $22 but it still didn't fix the issue...ended up getting a brand new BAD relay...bought one from Nissan for $24 and problem solved.

[Linux2501]

How would I check if its bad I can jump the soldered ends and make my car come on electrical wise not literally the engine turning over. And there is what looks to be a burn mark on the vonnection. And

[1fastser]

Did u say u had an FSM? I think there's a procedure in there for checking various components and their resistances, ect. Snap a pic...a burn mark on an electrical part doesn't sound good.

[Linux2501]

Alright I will when I get to the shop today but here's something for you, swapped wires on the starter relay, (the one with the two connections going to it) and whenever I connect the ground to the battery even with the key in the off position, it starts itself or just turns over.

[1fastser]

congratulations, you just hotwired a car! :)

Sounds like you've got some wires crossed somewhere.

[Linux2501]

Lol I know I'm trying to get them all sorted out but everything seems to go to the right plug do u have an email I can send Picts to?

[1fastser]

Just post one here...I'm just one guy...

[Linux2501]

Here it is is this the right one?

[Linux2501]

Not to mention whenever I put the positive terminal onto the battery none of my relays clock would that be because of the starter relay?
