Motor shut off and won`t start.has spark and fuel pumps run when key is turned on.will start on carb cleaner when sprayed in air box.Fuel press?any Ideas?

[rodbolt17]

carefully inspect the VST for water, remember pumps are stupid and don't care what liquid gets sprayed.

rail pressure test is the first place I start.

Checked both filters and VST for water.minor droplets in sep.Where is test port for fuel press test or is there special adaptor ?

[madharchod]

simple logic if it starts with the spray then it has fuel problem that why it aint starting ,check the fuel lines and as Rod bolt recommends the fuel pressure you should have a running engine

[rodbolt17]

the F250 takes a special adapter to check rail pressure.
the VST drain is that pink tube on the lower port intake runner.
