Alas, while the wiring was to the wrong terminals on the coil, fixing it still did allow the car to pass the test on pin 1. No continuity on the line to the ecu plug...great.

Yup it's completely backwards on mine, keeping fingers crossed that this is the reason the ecu isn't getting signal to pulse injectors. Will update when I fix this later tonight.

I think I may have found a new mystery in my car.using the color wire diagrams available for 76 280z I was trying to trace the wire from the negative terminal on the coil to the ecu. According to it I should have 2 blue wires coming off the coil one to positive one to negative. I have a black and white on the negative and a blue on the positive.which if I'm right means that it's a 77 wire harness, according to the 77 color wire diagram,and the wires are going to the wrong terminals. I'm gonna swap them and do the test with the ecu plug when I get home from work tonight

Ok I did all of sections of test 2 in the efi bible the car failed ignition coil trigger input. Passed everything else though so now I no where to look

Oh, fuel pump runs and I'm getting spark. Pulled the hose off the top for the fuel filter to a gas can just to see if it was pushing fuel to the engine and it is. Spark test was done to and the starting fluid. It will start with the fluid. Gas in it is brand new, was replaced when in ad to pull the tank for repairs.

Clogged fuel rail was more my thoughts on one set of injectors getting fuel but not the other. The ecu thought came from it just not starting based on what's been replaced. I have not encountered the 10 min run issue in a long time because it just won't start now. It's a 76. I'm gonna try the tests in the efi bible and go from there.

Ya probably a good idea. Have been meaning to, whenever I'm about to I take a 2nd look at thing and notice something else broken that could be causing it To.

Ok, so year 1 it stopped running properly and was really hard to even get started. It ended up being the starter. Replaced that plus plug wires spark plugs cap and rotor while I was at it for good measure. Then it was running but killing battery, ok had a zx alternator that I had rebuilt so did the zx upgrade. Year 2 replaced alternator and it's no longer killing battery but now it will only run for 10 minuets at a time and need to cool down, kids and lack of cash gets in the way of much work, fuel pump also died this year. Year 3 replaced fuel pump, car fire right up till I gave it a little gas and sputtered and died. This year had been the most work so far. Got the tank cleaned and welded as it got a small leak from where PO whacked it off something. Initially I was not getting spark the new ignition relay fixed that. The fusible links where shot(the holders to) so I found a stinger max4 fuse block on eBay and did that upgrade to. Finally after it not starting it came to the injectors(which appeard to be the original ones) . The car will start with starting fluid but not stay running. Fuel is getting to the rail. One thing I did notice is injector 1,2,3 had fuel in them when removing the rail where injector 4,5,6 didn't have much at all(numbered from front on engine back). My thoughts are clogged rail, fuel pressure regulator or failing that ecu.

This car was not taken care of by the PO. The owner before them replaced the floor pans, put an exhaust system on it and also got fiberglass quarter panels installed. It ran and drove when I got it 4 years ago, but I'm fairly certaint it was on its last legs the because of the sheer amount of things that needed replacing. The long list of stuff I replaced looks like I was just throwing parts at the problem but all those things where dead or dying on the car when I got it.

Sorry ya injectors where essentially the last thing. The old ones where toast plugged and old. I have replaced the fuel pump, the coil, the fusible links, the starter, I got the ignition relay from Dave Irwin, plug wires, spark plugs, distributor, cap, rotor and the fuel filter. The afm is working, I am getting spark and fuel is getting to the engine. The only thing I am thinking now is the injectors are not getting signal to pulse.

Well just a update, injectors installed. Car still won't start , now at a complete loss

I tried nissan first, they are showing no stock unavailable in all of canada.

Thanks for the info in the bolts I will do that. Was gonna order online but it is 7 for the bolts and $60 for shipping of the bolts so decided screw that!

Awesome info thanks guys! I have the new connectors just ordered the orings should be in tommorow. Unfortunately Nissan is showing no stock in Canada for the bolts so I'm gonna have to do some looking. Thanks again for all the help.

I recently bought a set of 6 remanufactured FJ3 fuel injectors for my 76 280z. My only question is do i have to buy the o-ring kit and holders and if so are they specific to this injector or do i buy the one that is listed for 280z. Ive been doing some searching and seem to be coming up on blank. thanks
