That's how it's already wired.

yes, the oem ignition is still there just a turn dial now instead of key's, later i'm going push button but need to takle one bug at a time. The pump is on it's very own switch, from the battery, to the switch, to the pump. A hot wire i guess. i did use the factory black wire as my pump ground assuming that's what it was, to ground the pump. the switch has it's own ground.

No, but i did leave a part out. Thank's for the correction. I did use the green wire but just cut it and connected my red power wire to it, under the passenger seat. So just one power line going to it. I ditched the ecu, so i had to hard wire it to a switch. Swaped to SU's.

Haaha thank's again, got it today, life saver! I will enjoy it as much as i can.

How would i find out? How can I test for this? Is there a quick fix for it or a thread on it that I might could learn some info from? Thank's for your time...

Thank's Bigoak, I'll give it a shot, that input help's.

Arne, Your the man! Alway's helping me out, thank's allot. She ran / stumbled for around 5-10 second's then died out.

I put in an inline, low pressure fuel pump, and hot wired it to a switch. The wiring: From battery to an inline fuse(30amp) to switch. From acc on switch to the fuel pump. From ground on switch to Firewall to ground it. When i wired the fuel pump i just put it back where the OEM pump went and wired the power wire on the pump to the green power wire at the pump coming from under the passenger seat area. Then wired the ground on the pump to the black wire that ran with the green power wire, assuming it was a ground. It work's great, come's on when I hit the switch, shut's off when I turn it off. But when I had it running and turned the pump and the ignition off, it kept running, stumbled a hair, then died. What is causing this car to keep running if the ignition is off and the pump is off? Is it left over carb gas burning off ? Or an ignition problem?

This is my problem, thank's for the help everyone. I have trash in the line's-carb's and the old gas mixed with the new did indeed gum thing's up a bit. Have a helpfull hand on getting that SU rebuild dvd, and I'm going to clean the tank, line's, and do a quick rebuild on the carb's for good measure. Then tune. This should fix my problem I think. I also noticed my fuel pressure gauge gave out too. Probably got gumed up too, it was a cheap POS anyway, so is the regulator, there the great old Mr. Gasket one's. Should of called there brand Mr. Crap-it. Going to replace those too. Everything I've ever saw from them is garbage I think, not accurate, and cheap made. This stuff came with the car. So the owner before me must have had worst skill's than me, had to replace or reroute a bunch of stuff, wire's, line's, etc. Getting the bug's worked out now though, next stop is the clutch system.:stupid:

280-master, Thank's for the link's. That help's, just trying to make sure I get the right stuff the first time! I plan on doing a ''how to'' for the fact's section for this while I'm doing it so other's don't have to peice info together on here.

Thank's everyone, my problem was bad gas that varnished the inside and garbaged the carb's. Learned from this mistake. I'm goung to clean the tank out and rebuild the carb's using the SU dvd kindly being passed to me by a fellow Z member here at Classic Z. Thank's again Citjet. Then one day i'm sure i'll return the favor for someone else here, I figure by the time i get everything fixed and all the bug's worked out, I'll have some good knowledge of the classic Z from the inside out. I do everything myself so I learn from it, that way, if something goes wrong, I can find the problem fast and fix it even faster. Thank's everyone for the help. And Bruce, you will be hearing from me soon!

10-4 good buddy! We get mail but Carl lost a wheel and the horses still need to be feed! Thank's man that's awesome and would really help me out a lot. I'll pm my address, i'm going to need it, i'm going to rebuild from the new part's that are there and pick up a few that i need so i can have this baby ready for that panhandle meet for sure. Thank's again! I even got a great spot for that meet one day in the future, i nice island around here, water is great and the hotel parking lot is huge.

great info, thank's.

Thank's for the input guy's, that help's. So what year 240sx caliper am i looking for?

Hey all, I've been on the forum's here for a little bit of time compared to some. Figured i would actually introduce myself finally. ''Supraman" my handle is going to have to change, I have a Supra that pushes about 400hp to the wheel's, but my love for Z car's has run deep for along time. It started with hotwheel's and matchbox at first, i had a ton of Z's to jam when i was a kid. Then when i grew up a little i bought my first Z. A jet black 86' 300zx n/a, it was bad arse for lack of term's hahaa. I still have it, but blew the trans, looking to do a 5 speed swap from the crappy automatic. Then a good friend left a supra turbo for me, rip owen. So it was all nasty and mean, but not really a daily driver ya know.... But a weekend destroyer! Eventually it gave way to me pounding the crap out of it . So i purchased my dream car....finally at 27 years old ,i had what i wanted, a first gen Z. An eBay auction and 610$ later...it is mine! A 77' 280Z. Some rear quarter panel damage but fixable, rebuilt motor and a garbage set of weber dgv carb's that had no linkage and need serious over-hauling. So i pop the rear and find the EFI back there and traded it out for chromed out SU's on bling manifold's. Making good progress and got it running too. Sound's awesome. Big thank's to member's here for helping me out with my prodject, i'm going in head first and blind, but i have some decent machanic skill's and lot's of tool's. Thank's again to the one's who have helped me this far. Glad to be here finally.
