Hi Y'all,
I have a 4.2 L6 in this truck. It was running fine until one day it would not start anymore. I've checked the fuel pump and pressure is within tolerance (52psi). it does not lose pressure either after sitting for a couple of minutes. When I crank it, it delivers over 60psi on the pump and I also checked the fuel regulator...all good. I got a good spark...but does not even come close to firing up. The only way it will start is with a steady stream of starting fluid through the throttle body. there is no MIL light illuminated. Any thoughts? I'm stumped..
