No Green Light!

Blowby · 10-20-2006

Controller was working fine then all of a sudden, no pump light.

Connected 12V and pump works. When I start the controller the Red light turns on and the Yellow flashes 3 times, no green at all. When boost hits my start point no green light.

Should the Green light activate during initialization?
I have another controller and will try that one next.

Check your Map sensor connection with a volt meter to verify the controller is seeing increasing voltage as you get into the boost. You can also test the controller by tapping the grey wire to the green. This will send a 5v signal to the controller and the pump should come on full.

If it's one of the newer controller you can also check to see if any wires got pulled from the inside of the controller. They are held in place with terminals.

I was checking the connection from the map to plug and was getting a good connection. I noticed that the controller would work then stop. I returned the map sensor to Summit a week ago for a replacment, should get it back soon. Post results when installed.

Summit replaced the map sensor which I reinstalled and I also soldered the connections to the OEM map sensor wires instead of a crimp connection. All is well again.
