AEM - Open pump driver code. Please help.
I have AEM controller, quite new, only about 10 hours of use on it. I get the 2 blink code at random. When I don't have the code, the pump works ok, but I never know when I'll get it. Today I was under boost and it seemed to work fine, with a solid light, as soon as I backed off the throttle I had the 2 blinks. If I went back into boost I still had the blinks, so I assume that then I wasn't getting any water.
I've checked the wiring and it seems fine. Contacted AEM and they weren't much help.
Can anyone tell me how to troubleshoot this, or tell me where I can find something like a troubleshooting flow chart?
I really want to get this fixed and it's hard to find info about these things, there don't seem to be many people using them, relatively speaking.
I have a track day coming up in two weeks, and I really need to get it fixed by then, since I count on the water injection to protect my engine from detonation, and it's totally untrustworthy now. I'm getting a little desperate. Thanks for any help.

7+ wires and all have to be done correctly with good connections.
Then if you also did a fuse, more stuff.
Very carefully verify ALL your connections are good.
I found out that the same +12V source MUST be used for the control unit and pump.
The arm source can be different.
