Flooded cylinders with gas. Help please!
The other day I was driving my 1992 xj and it started missing and almost died. I high tailed it home and checked everything out. Had been smelling gas for a while intermittently but had no time to look into it. When I put gas in, there was an extreme amount of pressure, even blew gas out of the fill tube. Changed the plugs, wires and fuel filter after it wouldn’t start back. Now I replaced the fuel injectors as I thought they were stuck open. Got the Bosch 4 holes by the way. Still hard to start and flooding incessantly. What is causing this? By the way I can hear a clicking sometimes after trying to start and it not the exhaust heat tick because the motor isn’t warm. I’m stumped

My first thought on the flooding is the fuel pressure regulator. Pull the vacuum hose and if there's gas in it the regulator had gone bad.
The ticking is probably the lifters bleeding down, pretty common.

Are you throwing codes? That might lend a hand in explaining what the problem is. You could be running extremely rich (enough to flood the motor) because of a computer problem possibly? Also, back pressure when your filling it up with gas can just be a busted vent valve on the gas tank. That happens on my Jeep too. Not bad enough to blow gas out though.
