Holley Fuel Pump
Hi Everyone,
I'm installing a red holley fuel pump on my 67 C10. I wired up a Oil Pressure Safety switch so it won't run with the engine off, but when I finished the wiring and hooked up the battery the fuel pump turns on and doesn't go off even though it's not supposed to turn on until the engine has oil pressure. Maybe I hooked it to the wrong starter terminal. Which one does it go on? Does anyone have any suggestions as to what I did wrong here? Why is the pump always on? Thanks for any help.

Re: Holley Fuel Pump
do you have it wired to a ignition 12v lead?
or a battery 12v?

Maybe I wired it on the wrong starter terminal. Which starter terminal is only hot during cranking (stupid question, but...)? I used a summit racing fuel pump relay kit and a holley oil pressure safety switch. Thank you! Last edited by j1970GMC; 08-25-2012 at 07:23 PM. |
