Hello everyone,

Hope you can help. I have a '90 300zx NA. It was sitting in a warehouse for several years. Here is what I have done thus far.

120K service (with all the toys)
New lifters
New injectors (370cc)
I went with an external fuel pressure reg due to the old diaphragm looking split in the old FPR.
Setup is... Tank --> Filters -->RH rail --> LH rail --> FPR --> Back to tank
All new fuel hoses, new clamps, new filters. And yes, cleaned the tank.

Car starts, idels, and can rev perfectly in P.
As soon as I put it in ANY gear, still runs... touch the gas, and sputters and dies.

I have looked at TPS all ohmed out clear and within spec. I am wondering if it is something in the FPCU? Anyone have any advice here? Kinda stuck! Thanks!!!
