I'm not sure if this has been covered before, tried search but no luck. It's a VR V6 1994 and to start it i need to turn it over and put my foot on the accelarater and rev it to start if i just start it with no accelarator it'll start then stall. Also when i put my foot down to start it, a large amount of light gray smokes comes out, smells like fuel. Anyone one have any ideas how to fix the problem? I'm thinking injectors or fuel filters are blocked but not sure.
