SR wiring problem -- no start condition

[jdm_master_X]

i did an SR swap for another user here a couple of months back and i left it up to him to get a battery for it to start up. its been a few months and it still doesnt start. i did the obvious tests for fuel and spark, power, and starter. all the wiring was checked out. i check it out and i realize that there is a harness connector that is unplugged. its part that is cut and rewired to use the KA plugs.



i dont know if this matters, but the wiring harness was previously used in an 89 coupe and then was swapped into a 92 FB. the harness was spliced with connectors from a SOHC. when my friend and i were plugging in the harness i dont remember seeing the female side of the plug that connects to the chassis. i took a look in my FB and didnt see any sort of connector that looked like that. i do see the identical wire colors spliced into my harness and the car runs fine. as far as the other swapped car, no success.

do the zenki and chuki use the same connector of the same shape or are they completely different? is there a way to hardwire the connection?

so you used a SOHC harness, wired it to fit a DOHC but maintained the SOHC connectors? thats confusing.

If you did the tests for fuel spark, etc what were your results? did you also check your grounds? What was missing when you tried to start the car? Fuel, spark, starter...we would need to know what it does when you try to start it. Does it get fuel and no spark...is the starter working, is there spark and no fuel?

the part of the wiring that you have marked looks like the connectors for the fuse box? More details please?

the car just clicks. it has spark and fuel because i tested the injectors, plugs, and major connectors and they are all getting the correct amounts of voltage. all the major ground wires to the chassis were on and were also getting voltage. everything from the last car was swapped into this car so nothing was missing.

i went to look at it again, and my wiring was up to par. color for color and everything. but im going to double check to see that they didnt come lose or frayed.

what i wanted to know was what that gray 8-pin male connector was for.

The sr swap should have been easy enough. The repinning happens at the big grey plug and the brown plug near the filler for the windshield wiper fluid for the most part. The cutting happens at the white plug after the ecu plug, everything else should have been left alone.

The place where you made the cut are the plugs that I'm talkin about. Those go to the front of the car just behind the passenger headlight but in front of the fuse box. Those just need to be repinned and some wires tapped to others.

well see thats the thing. i wired it up the first time in another car and that car ran for a couple of months until the same guy asked me to swap the motor into another shell. so of course it should be 99% plug and play with the exception of the wiring near the fuse box. the thing is that the first shell had a female connector for the gray connector i pictured above. but in the new shell it doesnt. so now im tihnking of just hardwiring the connection again if the connector isnt found.

I just put in an sr harness that was wired for a zenki s13 put into my chuki s13 and it's just plug and play besides redoing a couple wires because the previous owner did a poor job of connecting wires. The only thing I had to swap out with a chuki plug was the dash plug near the ecu that goes up to the dash.

If it just clicks I'm assuming the starter plug is not connected onto the starter or loose enough.

have you checked your fuses. also if you are gettting spark and fuel something should be happening other than clicking because there going to be combustion. are any of your lights not working? check your fuses. you also didnt say that you checked your ground.

I am having problems believeing it is an electrical issue because you have said your car has fuel and spark but nothing else. you said the starter is engaging then all of your main wiring to get the car running should be fine. Is you IACV plug correct?

if you think it will work switching the connector from the first car give it a shot, but make sure you have enought wire and note changes that you make.

My money's on bad starter connection.

[Blown240sx]

I was thinking the same. Clicking is usually a sign of bad bat or bad connection.

the plug should be in the passenger fender somwherethey are all the same and it should be there

i have done 2 89-90 swaps and 3 91-93 swaps
