Fuel pump secondary circuit - What is it?????

[bloopbloob]

I Did a KOEO test the other day, and pulled a code 96 - (fuel pump seconday circuit fault/ high speed fuel pump relay open). what does this mean, and how do i fix it??? i have a walboro 155 aftermarket pump installed, would this have anything to do with the code?

I belive that code is 95 isnt it? Thats what I always get anyway and its that code. From what Ive read its nothing to worry about, at sometime the fuel pump didnt kick on or something like that. Ive had that code ever since i got that code and my friend has it too. I really wouldnt worry about it but thats up to you, but maybe if it just came out of nowhere. Do a search on it and youll find some info about it.

96 means the puter noticed the FP lost power for whatever reason (stalling can even cause it).

If you are running OK don't worry about it. The fuel pump lost power at one time or another and the computer noticed it. If you are having problems, post again and I will put up the code 96 test path for your car.

Probably a code 95?? Nothing to worry about. If you erase the continuous memory, probably will go away. I have a fuel pump cutoff switch... if I attempt to start the car with switch off, will get code 95 again next time I check codes. After clearing continuous memory codes, gone.
