Rb25 R32, Won't Start, Now I'm Stumped

[Traah221]

Alright guys, need some real help here. I had the car able to start and idle with no problems, albeit kind of rough, as I had yet to swap the pins for Injectors 4 and 6 at the ECU. So, I started it a few times to check for leaks with the injectors wrong, but I saw nothing wrong with that. The problem is, I then swapped the injectors like they're supposed to be, and now I have nothing. It will crank repeatedly, almost sound like it is going to fire, sometimes fire along with the cranking, but never actually run under it's own power. The stumper is that I swapped everything back to the original way I had it running not hours earlier, and still couldn't get it to fire. I have already checked spark on all my coils, so that's one main area down. Total troubleshooting list so far is:

-Tried different Ignitor

-Tried new coil packs

- Switched out the CAS

- Put wires in correct order and reset the ECU

How would I go about checking my fuel supply and air supply, or is there some glaringly obvious problem you can point out from my symptoms?

You have probably flooded the engine.

Remove the spark plugs and dry them (they are probably soaked in raw petrol). Also, the problem with swapping out the CAS is that you need the engine running to set it correctly.

Try adjusting the CAS as you crank the engine. Also, try starting the engine with WOT - lets in lots of air to mix with the flooding fuel.

▲ /thread!

once you have tried the above report back and we can go from there but the above is a pretty good start

Right, I'll have to get some shop time, but as for adjusting the CAS as I have someone crank the engine, what exactly am I listening for? Never honestly messed too much with adjusting the CAS, just set it at stock centered.

Right, found my problem. probably a good bit of it was, when my Cam gear cover was taken off, my CAS bracket was completely snapped off. Good times. Replaced it with one from a nearby RB20, replaced all my spark plugs and cranked it for awhile with the fuel pump fuse out, drying the cylinders. Plugged the fuse in, and she fired right up. Now, next issue is that I have no electrical power to any of my accessories. I have headlights and a radio, but nothing else. No windows, A/C, Rear lights, brakelights, turn signals, and my gauge cluster isn't working at all. Has to be a single cause, with everything electrical going at once, but what?

Okay, so an update on this and a bump on the thread for others who may have this problem. I think this was a precursor to my problem now, which is the above problems, difficulty starting, needs brand new spark plugs to run, won't start again if left sitting overnight even, and a terrible miss through all RPMs, running on 4 cylinders it feels like. So, I'm sure if you have these issues, you undoubtedly pulled your plugs, stuck them in the coils and grounded it, then cranked the car to check for spark, and you probably saw spark, but be VERY THOROUGH, check all your coils for the SAME LEVEL of Spark. You may find, as I did, that, while there was a spark, it was in fact a very, very feeble spark on most of your cylinders. Now, this has degraded to a complete absence of any spark for me in 4 out of 6 cylinders, and a very weak, useless one in the last 2. I'm going to start at the ECU signals and start checking continuity up to the Ignitor chip, voltage out of the chip, then down the coil harness until I find the weak link. I'll post it up when I find the culprit.
