Vehicle is 99-00 integra with step down harness
All connections done at step down harness
To save the factory harness from being tapped in to
Now. CPR box has green , yellow solid and red flashing when cranking
With ignition error unselected I get a code 4
Select the box and upload no code 4
Problem is if I check my power and ground. Power is at coils and so is the ground checking cylinder one for pulse when cranking I get nothing
I checked at the cpr/ecu on sync wire and I get 6-7 volts with cranking
But when I use a spark tester on the spark plug / coil. No light flickering with tester
I wanna say the dizzy is jacked up. Or am I missing something
I tried a different ecu and just loaded the map on my personal ecu that has a cpr conversion so the ecu/hondata are out of the equation again what am I missing. I am stumped at this point
Long shot, but did this person every figure out what was wrong? Im running into the same issue.
