This isn't really a new member forum appropriate post, but seeing as I have no choice due to my post count, here goes.

I've been rebuilding my rx8 series 1 car for the past 6 months in my spare time and have pretty much finished, apart from being able to get it started! I would really appreciate some constructive help on how to fix/diagnose what my problem is. I've mostly been using the UK owners site for help over this process but the ideas have dried up so I thought I would try here.

The Rebuild includes brand new housings, full atkins rebuild kit including bearings, new D585 coils (earthed them under the airbox tray), new magnecor leads and spark plugs and sohn adapter.

I can't get the car started on the starter motor which is spinning at 280rpm, I've tried adding 2 stroke oil in to the chambers too. The car will tow start, but won't idle. It will stall if I take my foot off the accelerator. If I keep my foot on the accelerator, it will really struggle to move the car in 1st gear. I can only get it crawling then it will stall on me. If I just sit there holding the revs, it will cut out after a few minutes.

Over the process of trying to get it started, I've had 2 CELS: P0335 - Crankshaft Position Sensor Circuit Malfunction and P2096 - Target AF feedback system too lean - right bank.

Things I have Checked:

- Fuel injectors plugged in correctly (done this twice now, checked with wiring diagram)
- ECU plugged in securly
- Hoses plugged in correctly
- Cleaned MAF
- Cleaned ES position sensor - did 20 pedal stomp to reset

Here are some videos of starting and poor man compression test:

The low readings concern me - but I have been told the compression should go up once the engine is bedded in? Also told a conventional compression tester might not be entirely accurate for rotarys?

Video of turning over with no spark plugs:

Something didn't work..the compression should be way higher than that It could be really flooded though

Did you reset the ES sensor after the install....?

Are the coils and injectors wired properly?

There are so many things that it could be it makes it difficult

You should have 3 even pulses when you turn it over.....

I would confirm that your injector and coil wiring is good...as that is a really common mistake...and try and pull start it from there

If it is severely flooded it can make the compression that low.....thats what the video sounds like

I initially neglected to do this because I wrongly assumed the battery being off for so long would mean it has been reset. I have since tried a couple of times with no effect.

Yes, I have checked twice with the wiring diagrams, as I stated

The videos I posted seem to confirm that I do.

Interesting idea... I didn't know that an excess of fuel would reduce the reading of a compression test? Perhaps its worth really clearing the chambers out, adding 2 stroke and repeating the compression test?

I really can't think why my compression would be so low... with brand new seals, springs and housings

The first video has very poor pulses...sounds flooded.
that's why I mentioned that. I would pull start it and keep it running till it clears up the crap from the rebuild. If the plugs are fouled you might need to give them a cleaning or swap them out after it has burnt off the assembly lube.....
