I have an early 94 with a 4-line intake manifold, as far as I can tell there's no Schrader valve. Maybe I'm wrong or it's an inline somewhere. Any thoughts to check fuel pressure guys. Thanks! Really hoping I don't have a fuel pump issue, but I think I do

Z, here's a picture of a '94 motor, not mine but similar to my 3 rib. Schrader valve is on the passenger side, close to the windshield.

What's the issue your having? Recently my '94 is taking 3-4 seconds on cracking before firing up. I spoke to Dan Cragin at SPT a few weeks ago and he told me its the Fuel Pressure Regulator, a common G1 problem. Unfortunately you have to pull the tank out to get to it.

Mine does not have the valve. my car, when I bought it, used to stall coming off throttle when it got to idle rpm range. It quit doing that when I started driving it more..may have been related. Recently when out driving, it just died on me on the interstate in a way that felt like it was starved of fuel. When trying to restart, it chugged until what seemed like I forced every bit of fuel fumes out of the line. It turns over fine, just won't start. Acts like it's getting no fuel. I can hear the fuel pump relay clicking, so I know I'm getting voltage. I've never had any problem at higher RPMs...so I doubt it's the fuel filter.
