Is it the right? Or the other side? That's my AAR connection too. Thanks for any help. EDIT: Sorry, Ive found that the LFT side is the 12volt and RT for the ECU in my picture.

I'm wanting to learn more about ITB installations and any problems with this injection system. Search for ITB turns up zero.

I have an early '77 that has the hose from the valve cover attaching to the accordion boot before the throttle body. It takes forever to warm up. I notice a lot of those hoses going to the throttle body beside the one coming from the air regulator. I have the '78 FSM and it shows valve cover to throttle body. I guess I'll try it the newer way and see what happens. Just asking opinions. Thanks.

I recently bought my 280z a few days ago the car drives fine and everything but i noticed that the fuel pump is still on while the car is on ACC, i know for a fact this isn't right and was confused at why it was doing so. I looked under the car and found that fuel pump had been replaced at some point in it's life time and i retraced the wires and they end at the bottom of the passengers seat, they're connected to some sort of relay. i need help! i don't understand why the fuel pump is still on while the engine hasn't even started i'm scared it could flood the engine. I hate to take it to a mechanic to fix it for me and i figured i could do it myself. PLEASE REPLY!!! …

My car ran bad before I rebuilt the motor so I did a bunch of stuff trying to make it better like messing with the TVS. So now it runs almost perfect, it's like I'm in a dream or something, but at 2800 to 3000 it is like a power band kicks in. I've adjusted the TVS up and down for the past week and still can't get it right, I'm close right now so I'm asking, at that RPM the WOT contact is closed I suppose, so does the width between IDLE and WOT need to be farther apart? In my mind since it runs so much better when WOT is closed they should be closer together. Almost as soon as it's off idle contact it should be on the WOT contact. But I've learned to do right the opp…

I'm noticing that, after shutting off engine for awhile(to run into the store for 10-20mins)AND if the engine temp gauge is reading well toward the hot side(Before Starting),the engine is difficult to start...acts as if it is either flooded or can't get enough fuel initially and slowly ramps up to normal operation. After it has time to cool down, it has no significant problems starting.... Ideas???

I bought these injectors for my 77 280 about a year ago and finally got a chance to install them last weekend. It's an easy job. Have done it a few times on other Z cars. Before I bought them I had mine cleaned and didn't really notice a difference after that. So I decided to bite the bullet and buy new ones. What a difference! I run an in line fuel pressure gauge between the fuel filter and fuel rail. Ever since I installed it I can observe it bleeding off pressure over about a 2 hour period. It bleeds down to zero. It still does. Was hoping that it was one of the old injectors dripping but it was not. I know it's not the FPR because it is new so it must be the check val…

First of all if this posts twice, sorry. I have recently purchased a 76 280Z and apparently have a fuel delivery issue. I have replaced the fuel pump and fuel filter. The car is driven about 6-10 miles daily and a weekly trip of 20-30 miles. The car has been breaking down about once every two weeks while driving the car spits a few times and eventually stops. I suspected that I might have a whole in the pick up line in the gas tank. I decided to top off the gas every couple days and would typically add about 1 gallon of gas. The car ran about 2 months without breaking down. I thought that I had solved the issue and would begin looking at fixing the pick up line. A …

Stock 1978 280Z suddenly won't start and fuel pours out of the throttle body and fills up the air filter housing. If you push pedal to floor, it will start after about ten seconds, backfire and die as soon as you release the pedal. If you partially hold the pedal down it will run but it surges. As soon as you turn the key fuel pours out in a steady stream from the throttle body. Please help my son is trying to leave for college Thank You Randy
