Re: Cranks and Starts but immediately Dies

Interesting. I've heard of dust and gunk build up that required someone to spray it with carb cleaner to clear. Although even that is a little confusing unless they aren't running an air filter. I guess a REALLY over-oiled K&N might send enough oil down the line to gum it. But this is the first time...

Try to attach it again.
I logged in to see if *.xdf was an allowed extension, and it wasn't on the list, so I added it. Hopefully that will allow *.xdf files to attach now.

Re: Explorer 5.0 EEC

I don't have anything to offer, but I'm curious what you do find. Having such radically different behaviors with nothing other than the swap of the EEC, yet having very consistent behavior with a specific EEC is rare when all the EECs should've been XDT2. It leads me to wonder were all XDT2 EECs not...

Re: Engine running rich

That would do it, but what allowed it to get so dirty that it suddenly ran badly? Was it run without a filter or did you spray something into the intake that oil-coated the sensor? Anything like that?

Re: Engine running rich

Well, I have a couple of comments. First, your tune file is a BEB. The A9L is GUFB, so it shouldn't require a licensed def file if you are using the open source one. As a result, I can't do anything with it. If you've purchased a def file and did so because the layout is consistent with other defs y...

Re: fuel pressure fluttering

If this is at idle, you may be seeing the high speed fluctuations of your intake manifold pressure. And being the fuel pressure regulator's job is to have the fuel pressure track with the fluctuations in the intake manifold, this may be what you are seeing. However I would expect that at higher RPM/...

The last intake vac leak I had wasn't on my V8 converted truck. It was on my 97 Ranger's 4.0L. Apparently Ford put odd-shaped rubber O-rings in between the top and bottom pieces of the intake which eventually go bad and allow enough leaking that the computer throws error codes.

I get not wasting money or time, but you are talking about a 800hp build. This isn't a place to skimp. Do it right when it comes to getting the fuel from that pump to the engine which includes getting the "angry pixies" from the battery to the pump.

I don't have much to add on this other than to comment about the pump size. 450lph??? You are going to need that much? I run a 255lph in my truck and it was a drop-in replacement for the factory 88lph Walbro. The only positive I can say about it is the TREPerformance pumps are quieter than Walbro......
