Sometimes itll start with a little bit of throttle and be fine (after throttle is released). Sometimes it'll die a short time after the throttle is realeased. Sometimes it'll stay running if I keep a little bit of throttle...sometimes it doesn't. In attempting to start checking off the basics, I'm installing a fuel press gauge (setup from RV Morse) to make sure fuel press isn't dropping off for some reason. My question at the moment...I've disconnected both fuel lines at the throttle body and turned the key to prime the fuel lines and am getting fuel flowing out both the pressure and the return lines. This doesn't seem normal to me. What do you guys think?
If you guys have any advice on what to check after I've checked fuel and spark let me know.
