R33 S2 Won't Start (No Spark)

OK.. I've had my car off the road since Easter.

I did the 100,000 service myself (water pump, timing belt etc.). I figured while I was doing that it would be a good time to install a forward facing plenum, Q45 TB, adj. cam gears, ext. manifold, new intercooler + piping.

Long story short it's been nothing but problems. I think everything is back together correctly.. The thing is when I crank it, there doesn't seem to be any spark. I get code 55 - all ok via consult

What I've tries thus far:

Checked all plugs etc connected

new battery

new earth lead to neg. terminal

new lead from positive lead to fuse box in boot

spinning CAS with ignition on (injectors click)

reversing the fuel lines in case I got it backwards

test light jammed in a coil (no sparks when cranking)

Any advice would be appreciated.

other stuff on the car that worked fine before I messed with it:

RB20ECU with nistune daughter board

T04

splitfire coilpacks

Z32 AFM

Bosch fuel pump

Have you checked the earth points in the engine bay, just below the fuse box.

I had a problem for 2 years where if i used anything electrical in my car it would shoot to 2000rpm and stay there until i turned the applience off E.G lights

Its simply was arcing on the paint work so i sanded back a little bit and its been fine. Just start with the basics.

Have you checked the earth points in the engine bay, just below the fuse box.

I just connected the test light to the positive side of the engine bay fuse box and touched the head, block, manifolds and the light glows bright. So the earth must be good.

Is it possible to disconnect the coil loom and stick a multimeter on the pins of the plug? If anyone can tell me the proper method (multimeter setting, where to put each lead etc. What values I should get with the ignition on).

All coilpacks should have a common power wire. Normally the same colour on all 6 plugs. Check these have power.

U will need an LED test light to check there is a pulse coming from the ecu on one of the other pins in the coilpack plug

Hi i have just done a engine rebuild with a forward facing manifolf greddy style and i had the black earth wires earthed near the vct contoller and i had the manifold painted and a thermal gasket and my engine would not fire i had to remove the paint and for extra insurance i ran an extra earth strap to manifold then car has ran sweet since hope this is of some help

I give up. I'm towing it to BoostWorx

I'm pretty sure I had good earth to the plenum. I'll add a strap anyway. If I recall correctly the only place that wasn't earthed was the fuel rail. I figured that was by design due to the black plastic bushes?

Bostworx got it going: in a nut shell - Fuel lines backwards...

I tried that, so it may have been a combination of things like old battery/fuel pump etc. I just didn't go back and try the fuel hoses after the other "fixes" because I crossed it off the list.

Thanks to those who tried to help.

      R34 Skyline climate control unit transistor

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
