You may remember, I had problems with my z turning over after is 13 year cacoon. I replaced the sending unit in the tank. Had the tank cleaned.
replaced the fuel pump. and confirmed fuel gets to the fuel rail. Replaced the fuel rail(dealer part $$$ ) replaced the fuel/air regulator. Fuel is getting to the injectors. I know the motor isnt dead because if i supply fuel through the intake it runs(rich obviously but it runs very smoothly)
So I cleaned the connections for the injectors. Im thinking the injectors are bad (all would have to be bad for this theory to hold water) or the ECM is shot.
Im in need of the Z gods help yet again.
Am i way off here ???

 

I don't think you stated the problem.... So it does or doesn't run right now?

 

The odd's of all the injectors being bad are pretty slim. But after 13 years of sitting, it is definitely possible. Not sure if 79 came with a dropping resitor, but if it did then check that out as well. You can see if the injectors are firing by using noid light. Any autozone will loan you one of these. Also, the EFI relay can also be bad or not getting power. You still have a few options as to what could be wrong. The first thing I would do is get the noid light and verify if the injectors are firing or not. Then you can go from there. If they ARE getting a signal then you've got bad injectors on your hands.

 

Just wondering how good roten gas burns? any one don't be shy you don't have to raise your hands.

 

I thought I remembered him saying in another one of his threads that he cleaned the tank out already.

 

yep...


But yes... old gas (over a year old) should be drained & replaced. Gasoline tends to gum up as it sits & when it evaporates, it leaves a white-ish powder.

 

Hello i boiught a 1982 280zx turbo 2+2 that was siting inside a mans back yard for over 11 years with NO GAS CAP to boot... i boug the car for 300 dollars =-) i knew it needed alot of work.. but the old man went out side turned the car on and belive it or not he drove it to the front yard i coudlnt belive it with water and gas ... dirt etc.. when i got the car home it has massive ammount of rust in the fuel tank.. took off the fuel sender unit rusted to hell and back... i used 2 things of CLR remover and it worked like a charm to claen out the tank i had the tank refinshied ( i poser flushed out all the lines ! ) how did i do this ? well i used a old valve stem from a car tire i put in 40- psi in my air tank and i poswer flushed everthing out the way it should be cleaned out really nice !!! sure i had to replace the fuel injectors , fuel filter , and replace the hoses to the (* fuel pump ) too much to list im getting tired ! lol

 

do the injector test, if it fails that then you know what to replace.

 

So, I hired a mechanic to come by and check the noid light thing. It currently doesnt run. I can get it to run by forceing fuel in the intake but it won do it on its own.
So If i find the fuel injectors are good. I should look into a relay and possible ECM ?

 

well if you need parts for the 79 i have parts. I just pulled my running 79 motor out of my car with working ecu and maybe 1 year old injectors

 

Yeah, Ill pm you!

 

Darell that is a bad *** intak manifold man. looking good!
