Hello, I tell you the plob that I have with a 2.0 Motor Ford, it lights in a normal way but after 2 min stops completely and you start and instantly part, and if you accelerate thoroughly it does not pass from the 4000 rpm it empies how to do as a injection cut and the engine stops, at least the benzine marker indicates 1/4 of pond ... my doubt is a penn of the bencine pump? or pond level indicator? .... would appreciate a Pliss help ...
