Can anyone help?

Engine light came on so i ran the self Diagnostic on it and the Code it gave me was 21

as far as i can find 21 = Ignition Signal - No consecutive Ignition Signal

Using my own common sense the only thing that can translate to is something like a coil pack problem, although the engine seems yo be runnig very smooth.

Can any one shed some light on exactly what Code 21 is?

OK so all I am armed with here is a R34 service manual and common sense... but since no-one else has said anything... Have you checked your timing with a timing light? I think you will need one with a special "inductive" pickup, that clips onto "loop wire" for the coilpacks (has a yellow stripe I think?). As I read the manual if the timing is out too far, or if there is a variance of more than 25RPM between injector pulses, or a #($*& load of other things occur this light can be tripped.

Then again, sometimes you just need to reset the error codes and they go away and stay away. This is probably the first place I'd start... all you need is a paperclip. Instructions here are around aplenty :ermm:

      Yeah I spent close to a year finding one. I was even tempted to buy a RB25DE N/A head and port it out. That latter option, could still be an option.

      My head recently blew up on the dyno, been trying to find a replacement for the last 3 months with no luck.  Does anyone know where I might be able to find one? Willing to chase down any leads at this point  Cheers

      Waiting for a queue of Supras to get out of the way. Then the same conversion work to the box which was probably bought about the same day as you bought yours, by the sound of it. And hopefuly with enough Supras out of the way we'll finally get to do the box into the car along with the injectors and AFM so that the last 18 months of driving a highflow nearly NA can finally come to an end.

      Got my R34 gearbox around 4-5 weeks ago. Came into some extra $$ recently and after I cleaned the mess off the notes, I thought, might as well buy that R34 box I've been pondering.  In that time I've pulled the engine out, replaced rod and mains bearings, done a few other engine things that are much easier with the engina out eg PRP oil pump upgrade, replacing wastegate coolant lines, installing Turbosmartass turbo oil pressure reg, made some mounting brackets for some of my mods that are "hard to reach", converted the R34 box to R33, put the engine and new gearbox back in the car. Plus cleaning ...Oh my god so much cleaning when doing such a project. Yep I'm a busy bee, buzz buzz. As part of the gearbox project, researched posts and found this thread (In which i nailed it for the OP), hence the post here # logical thinking.. Not all about you old boy, SOrrryyy. Dare I ask,  how's yours going ,> Or you got it done yet, and if so why didn't you post any of the tips I posted to help other members? ???
