Celica Swapped 1JZ - In need of Fuel Pressure Regulator?

[SupraFreak13]

I know it's not a China Walbro...I got it from a reputable source while I was working at a well known performance shop.

Today I put a new fuel filter and changed the oil and oil filter. It's still breaking up once the RPM's climb under load. I need to pull the inlet line to the fuel pump and see how it acts with less hose and no restriction.

I spent the last hour trying to upload a video I took, but I can't get the quality any better for some reason...it's hard to hear clearly, but you get the idea.

Every time I step on the gas it will run ok at lower RPMs then it breaks up and then won't rev anymore.

Yea, I know I have one cracked coil for sure. But I've read on here that even with a lot of spark scatter it should run fine at lower boost and power levels. Its seems it only cause a real problem when people try to turn up the boost. I still think I have some kind of fuel line restriction, or the pump itself went bad, maybe from running with air getting in the line, causing the pump to burn up prematurely.
