I jumpered the plug, so I know the car runs, but I'd really rather have a working relay there. The bible is mostly good for understanding how the system works and providing simple test procedures that can be performed with a multimeter for all the different components. Chances are there is less than 1 volt going to the fuel pump. The only fusible links i havent changed are the ones on the relay box that are closest to the battery. Bottom line, car hasn't run in a year, head was pulled and tanked, and the car is back together now.

This new one, as you can see, has a black jumper wire connecting the two relays which then leads out to an actual ground wire with an eye.
I cannot find these in my car. Of course, this is a temporary fix, and I'd hardly say the job I've done will allow for reliable long term operation. Kind of surprising considering how long some Japanese brands stuck with carburetion. I dont see 12V on pin 10 of the harness. I dont see 12V on pin 10 of the harness. These things weren't know for great wiring thirty years ago when they were new, and thirty years hasn't helped.
A bad ignition switch or ignition relay could prevent the signal from getting to the relays. Thanks Hey Smokey and all, I don't think I can be of much help on this one but I was wondering if anyone knows the reasoning for the voltage to the fuel pump to be cutoff while the starter is engaged. I need a new strainer though, does anyone know where i can get one?? The big one above that had a lot of blue wires, the one to the far right i believe is the one ofr the fule injection relay and i dont know what the others go to. It's a little harder to work with because there are so many choices, but it will have specific tests for your 1978 car. But in my case there is also a mechanical fuel pump as well.

If it has power, ground, and ignition pulse to 1, then it should be grounding your injectors. Here is a picture of my fusible links I upgraded the grren one is 40 amps, and the black is 80 ithink can't remember off hand. On the fuel pump thing, remember the fuel pump only gets juice in the key switch start position. Brand new battery plugs, wires. Now the car runs, but misfires like crazy, and runs really rich blowing black smoke , the car sounds like it has a huge cam in it.
Ok think i figure out what was wrong. To check if the injectors are firing you can hold a screwdriver to them, tip against the body of the injector and your ear to the handle and listen for a click click click. Good move reading up and downloading the bible. It was released in 75 when the fuel injection was introduced in the first 280. Bill- no need to go through all the trouble you are describing. Quality parts many not always be the cheapest, but the value you get from our parts is superior, and value is what our customers deserve.
You seem sure you have fuel pressure at the fuel rail. I'm trying to point to the relay bracket with the beef stick, its a little off though. It reads about 38psi if i leave the pump running without cranking the engine. Here is a link to an AutoZone site with wiring diagrams for all years The first thing you want to check is the connectors. Check your emailed Sales Order confirmation to see the expected shipping time frame. I believe this relay is normally closed and it would pass relay power through its contacts.

Next step would be to check crank marks and cam marks to see is they are on right location. Maybe these sketches will help with the weirdness. May fit all years of Z31 from 1984 to 89, but typical of Nissan this unit probably does not fit both standard and turbo models. But how cold is it where you are? Keep a fire extinguisher handy.
