(Quick Fuel 30-199QFT Fuel Pump Relay Kit)ĭelphi Metri-Pack 630 Pull-To-Seat female terminals for retrofitting to a sealed relay socket connector: (Holley 12-753 Fuel Pump Relay Kit Instructions) Now the pump runs constantly with key-on. Simply use the green fuel pump wire (+12V) to trigger your additional fuel pump relay's coil (+) terminal #86. Fuel Pump Prime/Shut Off by Scottie-GNZ » Thu 1:40 pm Initially, the fuel pump prime/shutoff would occassionally not work, meaning with key-on, the pump would not shut off after a few seconds. I prefer to use 10 gauge wire due to its long length, especially for high output race pumps. It's only a 20 amp fuse and it also feeds power to the fuel injectors (& ignition coils - LSx, MOD & HEMI). The MS3Pro is a standalone engine management system capable of running sequential fuel injection on up to 12 cylinder engines. Please talk to Infinitybox technical support when you place your order to make this change. The 2nd fuel pump relay is used so the fuel injectors aren't subjected to the pump's amp draw. We can easily extend our fuel pump prime time to accommodate the timing required for the Sniper EFI system. I've always used a separate relay (shown below) because that green wire is still only 14 AWG. I've never used the ECU's fuel pump trigger wire to directly power the pump (even if it is less than 10 amps). Hardwiring an Evo 7/8/9 Fuel Pump (Crosses over to evo 4,5+6). When working properly, what stops the pump after 5 seconds of priming?The ECU triggers/controls the system relay. Well, I'd use a NEW relay because mine is bad, but you know what I mean. So I guess I could wire my old relay back in, and that should stop the pump (from what I'm reading). The red wire is the test/prime connector, which is direct power when the relay is UNtriggered.įrom reading through that thread you posted (and then following another link posted), I think you mentioned something about how the relay is (coiled) that causes the 5 second run time. Should be orange for constant +12V, which runs the pump when the relay is triggered. When working properly, what stops the pump after 5 seconds of priming? And while I will fix this, is there any issue with moving forward with instructions on how to do my first crank, fire, etc.? The key DOES turn it on & off, as I said, it just doesn't stop priming.Īlso, on that thread you listed, if that RED +12V wire he mentions is the red relay wire, then that's why it won't stop. I simply bypassed the old relay, and now the Holley/green wire is wired directly to the new relay via the old factory wiring. Per the Racetronix Hotwire Kit, the OLD relay is now simply supposed to trigger the NEW relay. Now, obviously it's possible something isn't wired right, but I've been over it again & again, and I can't see what it would be. Per the instructions, I turned the key to prime the pump. Global Folder is uploaded and I'm seeing sensor info on my laptop.
