you can get a noid test light auto zone lends it for free, they just hold $30) to make sure your injectors are getting volts, if that test good then you can go to the next thing.

now to test your fuel pump and make sure it is realy working, i had fuel to the rail without the pump even pluged in, its just not the right amount of pressure, you need at least 38psi to the frp.

so if you have a way to read fuel pressure then check it to make sure it good. if not then you can see if the fuel pump is getting any volts at all. if not then run the pump with the 12v mod or some people run 12v other ways, i belive by splicing the two wire going to the realy on the passenger side of the engine bay. aslo check the volts in the FP terminal in the diagnostic box, ground one to engine and the other in the FP.

Like MK3 stated, fuel is good, but not enough pressure won't do anything. Also you said you did the 1JZ swap, the car you put it into how long was it sitting? I did a swap, and the car had no fuel in the tank for years and the FP was toast.

No auto zone in Canada , What voltage should the injectors be at?
I have a broken ground wire and that's on the to do list so hopefully its the ground for the injectors or something fuel related lmao.
No way to check fp yet, thinking of getting the aeromotive kit, but i want to run new lines from the tank to the fpr, would steel braided work ok for this?? want to have a clean/ nice looking install.

The car was sitting for about 2 years while I was in the process of building my 7m-gte to the tits then decided to go 1jz for more options. Theirs about 5 gal in the tank and the fp is brand new 2 months old from drift motion

Fuel pump works like a charm no issues with it other then not knowing what psi its at, I still think I'm going to run the 12v mod with a nice little switch in it
