I seem to have a crank no start issue with my turbo EK9. The car cranks healthily but won't start.

I have tried 2 other distributors, new plug wires. I seem to be getting spark at the spark plugs and have also pulled the fuel injectors out to confirm I'm getting fuel. Timing has also been checked and is correct.

When the problem first started, the car would sometimes start and would run fine if it started. Now it does not start at all. I have also noticed the Rev counter doesn't move when cranking but not sure if this is normal. Rev counter works fine if car starts.
 
Haven't had a chance to check compression yet but is on my to do list in the morning. Spark plugs are only 1000 miles old but will also change them.

Have also checked thermostat ground and chassis ground as well as cleaning them up but no difference. The problem first occurred on the dyno when it went in for a map adjustment for new turbo. Car was switched off and would keep cranking when trying to start. Mapper also said there was no crank signal showing when it does this. The car did start back up after that after messing about with grounds and mapping was resumed. Problem has been occurring more and more often since then until now where it doesn't start at all.

Black yellow wire on the dizzy plug has battery voltage.
 
Hondata S300. Is there any way to view live data for sensors via the ecu? It may help diagnose the issue if so.
 
Yes you can download the Hondata Smanager program and will be able to datalog all sensors. The person doing your mapping are they familiar with the Hondata s300?
 
Will download Smanager tomorrow when i'm with the car and see if it helps. The car was mapped by Russ at Performance HQ and he has done all the mapping on my car along with my Evo. He's very well known and is familiar with the S300 so have no doubts about his work.
 
Downloaded smanager and datalogged the engine cranking both with full throttle and no throttle. The only thing i can notice is that iat correction is at -100 percent. Not sure if this is normal?
