It is my fuel pressure regulator, my turbo z started up today, finally! I was messing around with the fuel rail andi smelled gas, i took the vacume line coming from the back side of the fuel reg. and i reaked of gas, if i take the vacume line off and plug it up my engine doesn't do anything. it just stays the same. This would expalin why i was running soo rich(oil smelled like gas, cause my engine was flooding) and the more i cranked on my car the leaned my mixture got then finaly it would turned over. I plan on tweking my turbo up to about 14 psi (intercooled of course and bigger injectors if needed)for street racing and i need to know if i need a rising rate fuel reg. or an adgustable reg. or just stock replacment? Thx in advance
