The injectors and Ignition have seperate fuses in the harness.have to check each one im unsure which is which

make sure the timing is not over advanced or retarded.Skylines dont run at certain points.Did you install the timing belt correctly

is it series 1 or 2

They have a earth at the rear of the coil pack on no 6

make sure this is put back on.

have you tried jump starting the car

have you got comp in the engine

Plugs are dry as a bone. spark is fine, im checking injector pulse with a light... it has constant (+) current on one side but no

(-)current on the other side

Hi,

I had the same problem it sounds like when i rebuilt my engine, (400rwkw RB26) My mate did not tighten a hose correctly and it would rev freely to redline, and idel ok, but when driving, as I started to make boost it felt sulgish and would only go to 5000,5500 rpm and start to back fire and not rev any further.... I found that the plugs fowed, and it was not starting correctly, try to check your hoses for a spilt/loose clamp. You can connect a compressor to the inlet while you block off the extra hose and flow air through, try to keep it under 15 psi.

See how you go!

i assume u mean a test light?

ive never hooked up a test light to an injector to know what it would show

if u wanna check pulse you need a noid test light, it will actually show you the pulses

- yes it was with a test light and a logic probe...

- the plugs are sparking also

sorry man what is a logic probe?

logically speaking, you found the problem was the broken CAS shaft, that is a obvious reason why it shouldnt go..

so logically the problem is there, possibly a faulty part? or possibly but i doubt it damage to the cam gear where it meets up with the CAS

yeah i was sure it was gonna go once i put the NEW cas back on... :D

Maybe i should pull the new CAS off to see if it has snapped again.

the logic probe is a LED light thing...im not real sure how it works but oh well... a test light wuold be more than enough to check injectors.

**The HICAS (rear steering) is really noisy now to and the light keeps flashing on the dash...damn it..(is this normal?)

Ok, the car started this morning and the died after 5mins of idleing...So i pulled off the CAS and its snapped the brandnew CAS shaft... how can i mae sure everything is aligned properly? or is there other reasons it snaps?.....very costly part..i cant go breaking anymore of them

ive heard of this before.. and tis got to do with the cam shaft being out of alignment with the CAS shaft... take your exhaust cam cover off and suss out to see if all the cam bearing caps are tight and seated properly.. turn the motor over by hand to make sure the cam spins true and straight.

ok, CAR IS GOING AGAIN -----so far so good

Turns out i pulled the cas bracket off that is behind the cam cover..and found that it was missing one of its two alighnment dowls...which as a result was putting the cas shaft out of wack...and breaking the shafts.

- also car is still missfiring under load..so im trying a stock ecu and a coil ignighter module 2moro.

cheers for everyone's help its been great... still not 100% but progress has been made.

cheers to all

      Could be falling edge/rising edge is set wrong. Are you getting sync errors?

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.

      Neg, the top one is actually for the front. The sizes are 18x10.5 +18 and 18x11 +32.   I measured many times but I'm sure I'll have problems as this is the thread for problems.
