You think its flooding with the fuel pump connected, but not with it disconnected? I'll check the spark plugs and try your suggestions.

It only starts with low fuel pressure. I'm going to try and blow out the return line right now, maybe it's clogged and won't allow proper regulation.

Almost there. Progress update: Bonnie starts and runs, however, it will not start if the fuel pump is connected. I read a suggestion online that I tried. I disconnected the fuel pump, cranked the engine (to reduce fuel pressure) and it started, but when I connected the fuel pump, it refused to start. Weird, but I thought it could be a fuel pressure problem, so I rented a fuel pressure gauge, took measurements with the fuel pump connected, it measured 42 lbs.. So I bought a new fuel pressure regulator. It now measures 36lbs, but still Will not start with the fuel pump connected. And if I disconnect the pump, it will start but very hard, and will not idle. Any suggestions, much appreciated. Troy

So today I had a friend come over, we made sure the timing is set right. We checked every injector, all have pulse, all spark plugs have spark. We both are stumped. It cranks over, no problem, just won't fire. We tried to spray starter fluid in the intake as well, made no difference. Any ideas. Coil, ignition, ?.?

I'll look at it tomorrow morning, got busy with some work stuff. I may need to take off the valve cover and look at the marks. I'll look in the morning thanks

Ill check tonight, if it is, how do you correct it

Yes, I have the wire plugged in, good question. I did check for spark on the plug, they are getting spark. That's what I can't understand, I have spark, obviously I HAD a lot of fuel, but still won't start, weird.

I was very careful in my rebuild, although I will admit it was my first, I took considerable time and followed the books. That being said, I could've missed, or not calculated something. I'll look through my notes, and pictures. Needless to say I'm concerned and frustrated. I appreciate the help. Troy

It seems the car is testing my resolve. The starter is cranking over as it should, but I can't get it to start. I tapped on the injector and the problem seems to be solved. But I still can't get her to start. Theses 40 year old cars are tricky at times. Troy

Fuel injector is stuck? Malfunctioning?

GAS GUSHING OUT! Okay, I have a good battery, checked and have spark at the spark plug, but still wouldn't start. I took each park plug out to see how they look, and everything was fine until I got to the last plug #6, and gas gushed out, maybe a quart or more! i do have an aftermarket electric fuel pump in it, and I had been trying to start it the past few days on and off. Any deas gang? thank you Troy

Siteunseen, I somehow snipped it off when I pulled the engine, but I did get the wires in the correct place, I suppose I should order, or find a replacement, good point. i did replace the battery, and it cranks over as it should. Someone asked if I added any parts in the rebuild. Yes, I upgraded the coil, tonight I'm going to make sure it is correctly installed, hoping to get Bonnie started! thanks for all the guidance. Troy

Yessssss! i connected the white wire and I have lights and the starter turns over, Bonnie lives, BUT....... the headlights are dim, and the starter only barely cranks over, even with a jump? okay you wizards, where to next?? thank you, thank you all. Troy

Zed, where red would that white wire be coming from? Over by the shock tower? I'm at work, so I'll look this evening. thank you.

Zed, i live in Washington County, MN. Are you also in MN? Just curious

Okay, so the black wire with the link is attached to the same post as the red from the battery then it's connected to the cluster of wires next to the shock tower... anyone have pics of which one its connected to? thanks

Here are photos of the battery and connections, the back of the alternator and the starter, I can see that I do not have the black small wire with a usable link connected to the starter. I also have two wires with plugs that I don't know where they connect. You can see them in the pic of the starter. I don't have any wires I can find to attach to those two? thanks for all your help

Thanks, I don't have a wire running to the starter with a usable link. Where is that small black wire connected, and it coming from the battery?

Just finished a complete engine rebuild on my 1975 Datsun 280z (I named her Bonnie) a few days ago. I've owned Bonnie since 11/1/2015, just 6 months now, and began the rebuild the end of November. When I tried to start it, I have absolutely no power in the car, no lights inside, no headlights, no clicking in the ignition, nothing? Hoping I didn't kill Bonnie. Here is what I've done so far; I've cleaned and checked the battery and terminals, all new terminals. Checked for power from positive, the only power I have is to the starter, no power to the alternator or the ignition. I've checked the grounds, all are good, the two bolted to the frame and the one to the back of the starter. Needless to say, I'm both stumped and frustrated. I can post pics of anything anyone needs, I appreciate your help. P.S.- Bonnie ran very well when I bought her, all lights worked, started every time, no problems. Just a tired engine. Help??!! Troy

That is nice looking

Looking for ideas on Best steering wheel replacement options, 75 z, I want the horn to function, thinking of a 350mm diameter, thoughts?

Thanks, it's ordered, excellent. Troy

Zed, good point on the tire diameter. Thanks

Mud, Thanks, that link didn't work, what's the name of the book, I'll get it ASAP. I'm on the hunt for an 5 speed. I think part of the reason I'm looking at a 5 speed, the car I bought has 14" wheels, maybe it would be a more comfortable RPM at cruising speed with some 16" wheels, right? I think I'll buy the rims, tires first, then see how comfortable the cruising speed is. Sound good everyone

My goal is to have a good cruiser at highway speed with solid acceleration 0-60, any thoughts on engine rebuild are welcome. Yes it burns oil, and smells of oil while driving.
