hey guys,

i have had my gtr sitting for about a year and went to start her yesterday and she doesnt want to kick over??

anyways i checked everything out and 4 out of 6 of the coil packs were sitting in water (down where the plug is), looks like it has been sitting there a while too. so i got all the cr@p out and fixed that up.

also, the fuel has turned to varnish.. i took the filter out on the pump side to find out if i have any pressure. i turned the key and some fuel came out but not that much and then after about 4 seconds it started dripping like it was clogged? i turned it off and then back on and there was nothing still? waited 30seconds and redid it and pressure and then it died again!

im wondering if the pump is dead, causing it not to crank over? or could it be the spark plugs.. new iridums.

ok, injectors were fully flow tested and cleaned today, they were fully blocked..

still.. she is not cranking over, put some aerostart in the vac lines and she wanted to start but couldnt..

i am begining to think its the CAS. it might be stuffed or seomthing??? i dont believe i am getting any power to the injectors.

either that or the ECU is stuffed!

i need some advice here!!!!!!!!!

It may have fouled plugs, pull one out and see if there wet with fuel.

so i take it you're sure the injectors are firing properly now? maybe pull them out and take the cas off and give it a spin too verify that they are properly working..

after having the coil packs sitting in water for so long perhaps the springs that sit inbetween the bottom of the coil pack and the spark plug have become corroded, try checking them out :D

U need to remove an injector plug from the top of one of the injectors and insert a noid light in the plug.

If u are getting a signal from the ecu the light will flash,meaning if u have spark like u say its not likely

the ecu. Next step would be to check compression.

U may be able to purchase a noid light from repco etc or borrow one from your mechanic.

Good luck

Mate trhis may sound silly but have you changed the fuel filter since you said it was blocked? If you really wana know, pull out your injectors, crank the car & see if they spray fuel. Maybe even one will do... Do the same with your plugs if you havent already

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
