I started it but it only ran on only a few cylinders, it stalled, now it won't start. It was 98 degees in my garage.
Could it be 'Vapor Lock'?
What can be done to check for 'Vapor Lock'?
How do I release a 'Vapor Lock'?
Do you

Pressure can be released at the schrader valve on the fuel rail. Cover it with a rag to prevent anything from blowing out on you and protect your eyes.

Watch this video. It explaines how to check fuel pump pressure. In the video, they will show you one and that way you will be able to identify your. It will be on the fuel rail.

Let me know if it helps.

Joe,

Thanks very much for your response.

The video starts with music as it opens.

As soon as the man starts to talk the SOUND IS GONE.

I released the Schrader Valve. At first some gas got on the rag; NO REAL PRESSURE.

It didn't start. I released more, then some air; but still NO REAL PRESSURE.

Now I want to locate the Fuel Filter. Moving down the line & hoping for the cheaper item over the more expensive fuel pump replacement.

I think a Fuel Injected system requires a higher pressure than a carburated system.

Where would I find the Fuel Filter on the 5.4 V8 in my 99 Expedition?

Thanks,
Del

It is near the fuel tank along the frame raill. What I would like you to do is check what the pressure is. If you have no luck with the fuel filter, check the pressure so I know what it is. Yes, the pressure is high. I have to look it up, but it is near 50psi.

Let me know what you find.
