mm0105 Will not Power Up
 

Using a 2001 engine harness plugged into my mm0105 MSPNP PRO. Wired power through X-16 connector.

The MS will not display the 12v red led when power is applied. Power and grounds are good.

The check engine light blinks once and goes off when the MS is first turned on.

I've checked the wiring over and over, and am scratching my head. I even tried applying 12v through the optional connector...no go.

Thoughts?

SOLVED: There are two W/L (white/blue) wires in the X-16 Connector. The small gauge wire is for the check engine light, and the larger gauge wire is for fuel injector power. I had them swapped....

50/50 odds.....LOST!
