fuel line problem
I have a 1991 Ford Ranger 3.0.
It is in good shape but has fuel issues. So far I have replaced the fuel pump, changed the oil, flushed the radiator, replaced the fuel filter, and replaced the starter.
After replacing all these parts the truck ran good. After letting it sit for about 2 weeks to get the title and insurance straight I went to crank it and it appears the truck isn't getting fuel. The fuel pump is working because I disconnected the fuel filter and fuel is pumping through the line. I can spray starter fluid into the upper manifold and it will fire. I was thinking it might be the fuel injectors are clogged or the line is clogged somewhere in between the fuel filter and the fuel injectors.
My biggest issue is that I am having trouble detaching the fuel lines. Any advice on how to detach the fuel line?
If the fuel injectors are clogged what is the best test to determine if they are and what is the best method to clean them?
