Figured this should be added here.
.
No Flash Codes?
Have you tried to see if there are any stored faults?
.
In the Service Manual, page 4-8 shows how to pull stored codes.
.
This is from page 4-8
.
When retrieving the stored OTC, refer to the following procedure.
Remove the OLC from the dummy connector (page 4-8).
Short the OLC [1] using the special tool.
TOOL:
SCS service connector [2] 070PZ-2Y30100
CONNECTION: Brown/red - Green
Turn the ignition switch ON (I), read and note the MIL blinks, and refer to the
troubleshooting index:

• PGM Fl system: page 4-9
• OCT system: page 11-11

NOTE:
• If the PCM has any OTC in its memory, the MIL will start blinking.
.
The special tool they talk about is just a jumper wire.
jump: Brown/red - Green
.

.
Then turn on ignition switch
count the flashes
.
Have a good day
