Want start unless you put gas in the plenum, wiil start and run until gas is gone. It has 45 psi gas pressure. When you can finally get it to start it idles like a new one, but when you openn the throttle it bogs. After sitting a couple of days it will not start at all. The first time you try to start it, it will sputter initially then just spin over from there on out. Any thoughts or if you have a particular question let me know. I have gotten desprate. Also, there is know engine light, it has not coded anything.

You should have around 65 psi of fuel pressure. That sounds like your problem. What engine do you have
