350 tpi HELP!

Why would gas be spitting out of a spark plug cylinder? Car has been runnig good and all of a sudden it stoped and would crank. I started to check each plug and one spelled like gas. I had a buddy crank it and that's when I noticed the spitting of gas. Does anyone know what this could be? Thank you in advance.

fuel regulator id be guessing. this would also make it harder for the crank to crank over with full solid gasoline in front of the piston....

Re: 350 tpi HELP!

Your injectors are shot. They are leaking down into the cylinders. Check fuel pressure with gauge on schrader valve KOEO, pressure should be around 38-45ish. Turn key off and watch gauge for bleed down. It should hold for a while if not bleeding down. If they are bleeding down, you'll know, the gauge will slowly or quickly drop to near nothing.
You got some testing to do!

Do a search on checking Fuel pressure and injectors here. Tons of info.
