Basically, that's it. Was running. Shut off. Now it just cranks over. Fuel pump? Where can I find fuel pressure valve on the fuel rail or any other ideas? Thanks guys

Hi,

It could be fuel, but you may have lost the ignition spark. Those are the two most common causes of a crank no start.

Do this: See if the engine starts with starting fluid. If it does and then stalls, we know its fuel related. If there is no change, then check for spark to the plugs.

Here is a link that explains how to check:

As far as the test port is concerned, it is on the fuel rail. See pic 1 below. Additionally, I attached the manufacturer's fuel pressure specifications below (pic 2).

Let me know if this helps or if you have other questions.

Take care,

Joe
