Might be the angle of your camera, but the pic from frsport looks like it's rotated clockwise a little more, and it appears the crank is on the far left mark.

Alright, I'm looking at the SR FSM in our tech section sticky.

Between the cam gears is 20 rollers, which in your pic looks correct.

Either the crank gear mark is off, the balancer slipped, you didn't have it on the compression stroke TDC, or you have an electrical problem (ignitor wiring, etc.).

Without looking at it directly, I guess that's the best help I can be. Sorry.

So my timing looks like it's setup correctly?

I haven't touched any inner mechanicals, so assuming that everything else is still set to stock just as it left the factory I will look into my wiring to find the culprit.

Also found that the end of my fuel rail by the last injector is bent because I could see sparks and smoke coming out from around the gasket. That's since been fixed. Funny way to find out you're backfiring though.

i know you probably dont want to, but last ditch effort pull the crank pulley and front cover to guarantee your timing is correct. Ive never seen or heard of a crank pulley slipping and throwing the timing marks off.

Also, timing looks correct. CAS seems a tooth off tho, set it counter-clock wise back and adjust timing from there.

It almost looks like you might be off a tooth yet in the retarded direction. I am assuming that you tried to turn the CAS in either direction to see if it sounded any closer to starting. With the J30 ignitor the wiring is the same except that the 2 outside pins are not used on each connector. Have you checked that you have a good ground? Which ECU did you get for your new one, does it match harness pin-out? Are the plugs fouled out? I know you seem very capable just more stuff to check.

Oh yeah, are the fuel lines hooked up properly? feed and return. I fucked that my first try also, and it took an evening to figure that out.

You also haven't been doing this for that long. Maybe not on an SR this time, but balancers do slip. I've seen it a few times personally. 2cents

Turning the CAS while cranking doesn't help at all. I tried starting with the CAS's "up mark" at any of the four basic directions with the balancer set to TDC and no luck. With the CAS intentionally 180 off I got a strong enough backfire to pop my front mount couplers off.

Edit: Getting spark at all four plugs. Balancer is set like so.
Superlight S13 - No 56K! - Page 12 377973_247

My grounds look fine, not sure how I would go about testing them besides measuring for continuity or resistance. Care to share any tips?

The ECU's tag is worn so there are no identifying marks. I do know that there is no internal LED and from what is visible of the insides it looks a little different internally. I will do some more digging into this, it's possible I have a late model ECU.

The plugs are new NGK BKR7E's, and I've been pulling and cleaning them as I go. I know all four injectors work great for sure. Wink

I would really prefer getting someone familiar to the SR motor to take a look at this. Does anyone know of any good local shops or people that could help?

Return line is coming out of the FPR.

Also, I installed a plug wire on Cyl no. 1 and checked my timing while cranking. I can rotate the CAS and be in the area of 0 to 20 degrees BTDC relative to the crank pulley while cranking. Timing is set at 0 degrees BTDC now.

I went through this exact same problem with my old KADE vert. I googled until my eyes were bloody and ended up getting the timing good enough to start by luck alone. I fall flat on my face and need to take baby steps when it comes to ignition timing.

Another thing I wanted to ask - Can anyone take a picture of their main coil pack wiring harness plug? Just trying to be sure something isn't backwards here.

Thats exactly what i meant, ive never seen an sr balancer slip. And ive been doing this shit for way longer than you know.

When I first restabbed the CAS I pulled plug #1 and verified the piston itself was at or very near TDC when the cams were pointing away from each other. The timing pointer indicated TDC on the balancer at that time.

It all looks like it lines up like it's supposed to.

If the balancer had slipped 40 degrees of rotation to the left, piston #1 would no longer be at TDC when the TDC mark was lined up with the timing pointer, right?

Correct, I was just giving you a different point of view that you may not have thought of.

Yup. The CP side plug that connects to the harness.

Aha! Your third picture almost looks like the red/green wire is in the middle, on the bottom. I have the red/white wire in that place on the bottom between the two black wires.

FWIW I took a few good reference pictures and made a diagram before resleeving my CP wiring, but it could have been wrong before I ever touched it.

Edit: Found the problem, my CP wiring is way off from how it looks like it should be. I.E, the black wire for Cyl 1 goes to the red/white wire at the plug.

It runs! Great horned monkeys batman, it runs!

Nobody really cares about wiring, but I'm going to post some pictures anyway.

As we know the RHD harness has a few extra feet when it's swapped into a LHD car. I will need to shorten this up. You can also see my fuel pump and ecu relays coming off of the fuse bank. I relocated the ignitor chip inside the car too. My wiring works as it should though, even the reverse lights work when the trans is in reverse. /Tons more wiring work left to do.

Also, it runs!

Superlight S13 - No 56K! - Page 12 IMG_0386

Cleaning up the fuse box. No more rats nest.

Superlight S13 - No 56K! - Page 12 IMG_0385

Now that it runs, let's bleed the clutch slave and see if it moves.

Dammit.

Glad it runs man, congrats!


I had nothing to add in regards to why it was not running, between s13.240sx, chizzle, and 600 nearly every base was covered. Ha.

Wish I was ready to run.

When's the first track day?

First track day? Dunno, I'll have to get some schedules and find out.

My camera is stuck on limiting me to 4 second clips for video. Need to figure out what's up and get that changed.

So here is a 4 second 1080P video clip of the engine running. It's all warmed up, ign timing set to 15 degrees. I underestimated the solid motor mounts - All I can say is damn. I had a set of sockets resting on the wiper when the car started and it sounded like gunfire.

Watch it in high def just because you can.

Just got back from the car's maiden voyage out back, behind my house. It's been a long time coming. Yeah, moving on it's own and all that.

Still have a few loose ends to tie up. Going to run and pick up some parts, renew my registration, and get my body panels back on. If my camera cooperates I'll have a video and likely a few speeding tickets by tonight. The car feels great.

Also, not having power steering isn't a problem at all yet. I was maneuvering in the back alley doing multi point turns and hardly noticed.

Till you hit the slalom or low speed Chicago box. Haha.

Its not a huge issue though. Try it out and see how you fare with no ps. You may be fine, won't know till you try it out on the course in real time.
