Just recently acquired a 82 280zx, its not currently running so i may be frequenting your tech forum.


Well just saying hello. Off to auto zone to get a injector test kit.

 

Hello, and welcome to the site!

 

Oh hi there...

 

so. car gets spark, the leads to the injectors lit the lights of the test kit, albiet it wasnt bright, but it did light. So. im thinking my injectors are shot. The car did sit for 15 years.

Its got fuel, pressures good. sparks. if i spray started fluid into the intake it'll fire. its rough but it runs for a sec. but since the injectors are not supplying fuel it dies within seconds.

Any one else have any ideas? Or should i try and get the injectors cleaned? or just get new ones?

 

Old gas in the lines/injectors. Did you change your fuel filter?

 

yah new filter. lines are clear. rails clear.

40PSI to injectors. i think they are just frozen from old gas.

getting em cleared out and cleaned tomorrow.

 

You can try what I did and just spray a whole bunch of carb cleaner in the pintle caps, and then rub a carb cleaner soaked paper towel or rag in there, and then spray some more carb cleaner in them...

worked for my car, started right up (for the very first time under my ownership) under it's own power after doing that
