Trouble with Holley AFPR
I installed new injectors and a Holley AFPR for TPI. Says it can go from 35 psi to 65 psi. I started it off barely screwed on there so i'm guessing thats like 35 psi, started up and died shortly after. I increased the fuel pressure slightly and it idled kinda funny so I increased it a little more and I smelled gas, sure enough its pouring out of the tailpipes. I shut it down and set it back to the lowest setting, now my car will start and immediately die even if I try to give it gas. Could I have fouled the plugs or something?
FYI: I dont have a gauge

NAPA has a cheep gauge.I used a 25cent piece in the regulator to get it to work right .I never had good luck with the holley regulator for the LT! motor but it worked for my L98.You need atleast 40 psi to get it going.You might have fouled the plugs or wiped out the o2 sensors .
