93 Honda Prelude wired for OBD1
1040 EMS v1.19
built H22 (OBD2 head)
OBD2 distributor casing with original OBD1 sensors (car came from a shop like this)
AEM Twin Fire C2DI (2821) (S1-Off S2-On S3-Off)
MSD SS Blaster Coil
Stock MAP
Stock 310cc Injectors

We've had this thing running, and now it has stopped doing so. No changes were made since the last time the car ran.

The distributor does not have an ignitor, and we have tried running the C2DI on both falling and rising edge for the trigger from the EMS.

We've tried the AEM as well as a chipped p28 with p30 code. I've tried playing with dwell time, coil selections, ignition phasing, have checked, rechecked, and rechecked again all wiring and grounds.

The car will crank and crank and crank but never fire. There is spark, compression, air, fuel, and timing (timing belt has been checked).

Have posted on the aem forum too. cal and log files available.

 

bump, anyone able to help us, we are really stumped on this one

 

ps jas is sexy


dizzy was 180 out and cylinder walls washed down (no compression?).

take that gaylude.

tuning soon!

 

I had this same problem not too long ago. I know you are using the CD2I, but after all the troubleshooting I did and testing, the rotor ended up being off 180. I thought that was impossible, but crap happens.
