Hmmm okay really really long shot... but does your crank angle sensor have a little pin in the middle of the shaft? After i did my 100 000k'er i couldn't get my car to start... it would just crank and crank. Went to swap cas's with an rb20 one and i noticed it had a little pin that runs through the middle of the shaft... must be something to grip on or something i'm not too sure it's been a while since i had a look at it.. but i simply made one up to suit and put it in and car started first time.

I'm sure that makes no sense at all but if it does it's worth a try... only takes a second so at least you can rule that out!

Yeah mate mine still has the pin through it and i know my cas is working fine

howd did u check injector pulse?, with a noid light?, so u have 12v at injectors and coils/ignitor, is ur CAS powered by 5volts from the ECU, sounds like it CAS related if both injectors and coils dont work. Just double check all wiring plugs cause you may have power and earth but a very high resistance in wiring, you havent painted over any pins or have any corrosion on them?

Hmmm yeah i think the cas might be alright and it's something else. As said above if it's 180 out or whatever it should just crank and crank and then pop one off i know from experience ha ha.

Why doesn't an auto electrician want to touch it? Too many possibilities and no idea where to start or...

yeah ONLY if it's 180 out.

If it's 90 out it won't backfire or pop. The guy who says he needs the help isn't really being all that helpful himself. You suggest something and he says, nope...replaced that. That doesn't mean shit when you have two faulty sensors. Always expect the unexpected and don't assume a 'different' sensor is always a better one.

This guy needs to be giving a little more information on what's happening. How has he checked things, what does it sound like when he's cranking it. Does it sound like it wants to go? or nothing at all?

even with 180degrees out, youd expect a backfire or something to show that its trying, ifs its total dead its missing one of the two key factors or both of them

Not exactly sure but I don't see any mention that it doesn't backfire or something.

180, 90, you'll hear something, might not be a big bang but it wont be crank crank crank nothing (thats if its only timing related)

i assumed that the engine was completely dead whilst cranking, because if it was backfiring or spluttering i would think he would of mentioned it. But one thing i've learnt about ass-u-ming is that it makes an ass out of you and me... :P

1+ on more info though, its hard to suggest a fix when you dont know whats going on.

I would spray some carby cleaner next, see if it gets the old girl going :D

Guys thanks for the tips i will start again with what i have done and what i have found. currently engine has no spark or injector pulse. CAS has been tried on a different car and worked. i have also checked voltage to CAS which is 12 v. i'am also getting no resistance to earth which means the CAS is getting a good earth. i checked both the 1 and 180 degree signals at the ecu with a multimeter and getting a pulse there. the injectors have 12 volts and the wiring back to the ecu is fine. injector pulse is checked with a noid light. i have check for power and earth at the coils and ignitor module which are fine. except im not getting a signal out of the ecu to fire the plugs. i have checked resistance values of the coils which are in speck. i have have checked the whole loom out of the car for broken wires etc. done a complete continuity check on the loom which was ok. checked every connector for proper connection which was ok. have checked all ecu power and earth circuits which are ok. i have tryed different ecus. i have manualy powerd and earthed each injector (with ecu dissconected) and each injector fires. CAS is in correct posistion and pin is in shaft and D locator is intact. i know it has to be something simple stoping this thing from going but i cant just seem to find it.

If you don't have spark or injector pulse, the CAS is fine and all the power to module/ECU is fine, all earths are good etc, injectors and coils bench test ok, then it is technically impossible to not have spark or injector pulse.

Congrats on having the hardest problem to fix....IN THE UNIVERSE!!!

But yeah, like you said...it will be something simple in the end.

Have you checked to make sure your noid light works on another car? and have you checked to make sure your spark tester works on another car also?

Now that you've tested everything else, you need to test your testing equipment :)

Just after some ideas from people who may of had this problem. not smart arse comments

It wasn't a smart arse comment. And if you feel you have to take an attitude like that, then forget it.

It was intended as a light hearted comment...maybe read back a few posts...do you really think I am not trying to help?. I offered you my mobile number via PM so that you could call to discuss it in detail but to my knowledge you haven't used that resource yet.

Offer still stands, though, I'm only here to help.

shit mate....

I would really listen to what dan has to say..... I call him and ask him shit and I am over 2000kms away....

what does it sound like when cranking? is it no hint of a spark or splutter? or is it just completely dead and turning over?

can you smell fuel?

is your fuel pump working? is it definately pumping fuel to the rail?

after cranking it over for a minute, if you take the spark plugs are they wet with fuel or dry?

have you tried taking the spark plug out, connecting the coil to it, earth the plug out like it was in the block, then crank it over and physically see a strong spark?

how old is the fuel in your tank? is it off?

what ecu are you using?

what injectors are you using?

what cas are you using?

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
