Ok so I don't know what else to do. I've swapped ECUS, AFMS, Injectors, Fuel Pressure Regulator, Fuel Pump and it still does not want to work. Ive tested everything and it all seems to get power and signal from the ECU but car still does not want to run. Any other ideas? because this weekend I will be starting the process of pulling everything I don't need for carbs off.

Well from what Ive found out the 1978's fuel pump was actually attached to the oil pressure switch instead of the AFM. Also my fuel pump works fine and turns on when I turn the key on. And the reason Ive decided to start replacing my injectors is because I was just gonna replace the pressure regulator and decided I should check the condition of the injectors and they are pretty trashed to the point the were almost falling apart.

filter is fine its brand new, i ruled that out when i first got it. im in the process of change the injectors and the pressure regulator and i have 3 AFMs to try and 2 ECUs so im hoping this will fix the issues if not im still tryin to find a write up on converting to carbs. tomorrow i should have everything back on and know for sure

ok so now it will fire up first try, then quit running, then if i wait awhile it will fire again then quit running. any ideas?

well i just got some parts from a friend. I'm gonna swap out the ECU and AFM. I cant tell how smooth its running because it wont stay running for more than a few seconds. I'm gonna try and hit the junkyard this weekend in hopes of finding injectors. but the only ones i might be able to get are off a 300zx and im not sure if those will work or not. And the reason I'm asking for a write on the carb conversion now is because id like to have it ready in case i end up having to go that route and not have to fly blind and guess.

Hello, im new to owning a Z I received it from a friend of mine and have been having problems with getting it up and running its a 78 280z with EFI. now Ive been having a lot of problems tracking down what is actually the problem or if its multiple problems, but ive not got it to the point i can start it put only if i disable the starter and let the cold start valve inject some a fuel a couple times then when i enable the starter again it will fire right up but wont stay running. so now i have a feeling it might be injectors or AFM other then that i have no idea and if thats the case i cant afford to buy a new AFM or all new injectors for that matter either since either would cost me at least $300 from what i can find. so im wondering if there might be a write up somewhere on how and what i would need to do a carb conversion. cause i can get an intake and carbs for the 240z SU carbs. thanks for the help
