Not getting fuel to engine.

Finally got around to getting a fuel pressure gauge. What range am I looking for?

 

While running/cranking, ~43.5 psi.

 

Thank you. He's now the 3rd with this setup. @loginfailed was the second. I took his welded-on plate idea, and did it to Lucario's. Mine, I bolted through the bottom of the frame. As I couldn't weld at the time.

Super functional and can handle any fuel type. Easy to add a pressure gauge tap as well.

 

Try disconnecting your battery for a few minutes and then reconnect it, should reset the ECU.

 

What other fuels have you used in your truck?

 

Can. Have not used any other than gas with ethanol.

 

How are you planning on attaching the pressure gauge? Does it have fittings to adapt to the OEM lines?

 

I got a loaner from the parts house, can’t figure out how to attach it to the fuel line. Doesn’t have a fitting like other make vehicles.

 

Gauge jumped up to 100 psi. Held steady at 80 while cranking.

 

That doesn't sound right, but definitely isn't a lack of fueling, according to the gauge. Lol

 

That’s what I said. Im not sure why it reads so high. But it’s definitely not a fuel issue. Unless it’s flooding or something.

 

You deadheaded the fuel pump. That is the max the fuel pump is capable of pumping. The fuel pressure regulator is not involved in your pressure test.

 

This is the line I tested circled in red. On the metal tubing side.

 

This. The fuel pressure regulator is located on the back side of the fuel rail. Your test PSI is correct.

 

I gotcha. I thought 43 PSI was a lot for a V6 engine.

So I'm getting fuel and spark, but still won't fire. What else can I check for?

 

I am unsure if our fuel rails even have a port to check for pressure but I'd check the regulator just in case.

 

This is basically what is needed.

Yeah 75 is a little much for something like that. I mean I pulled my spark plugs and they have fuel, just will not fire up at all. You'd think it'd at least spit and sputter if it was a fuel delivery problem.

 

The no idle doesn't seem like a fuel issue to me unless the regulator completely failed and blocked which I've never actually come across before.
