gearheadstik Posted March 23, 2007 Share Posted March 23, 2007 Hi, I'm trying to beat the clock on getting my car ready for sez and have installed turbo, megasquirt, and new exhaust in the last two days and need to know what makes the fuel pump come on in a 78 280z w stock wiring for now till after the sez....I have done some reading and have seen post about something to do with the afm...Do you have to jump wires to make it work or what...I figure some of you guys might know off the top of your head...I would appreciate it if you have a answer for me...Thanks Aaron Quote Link to comment Share on other sites More sharing options...
z-ya Posted March 23, 2007 Share Posted March 23, 2007 You can make the MS turn on the factory pump relay. You just need to verify that the stock ECU provides a ground to the relay to activate it (like the MS). I know the 280ZX ECU ground the relay to turn it on. The 280Z should be the same. You can either find that wire in the factory harness, or run a new wire to the factory relay. Quote Link to comment Share on other sites More sharing options...
