At the most maybe make a hole thru the center. But to get jammbed into the side. I cannot see how by it's self. I would think someone had to of disassembled it.

My wonder MADVAN is how did the pin get from where it is supposed to be, to jammed like it was.

Re: Truck just died, running fine, then started sputtering, then would not start.

My brother (a copier repairman that can barely change his own oil) said "dude, if nothings coming out the pipe (smoke or drool), nothings going in the cylinder"

So I took the fuel filter off. I just wanted to make sure I had not had some jackass put sugar or something in my tank and clogg it up. (I have a VERY vindictive ex, and don't put that beyond her)

When I pulled the filter (which unscrewed VERY hard) I saw that pin sticking out of the center post.. I was thinking "that does NOT look like how it did when I changed it last".

I still have no idea if the dealer did put it together right, and just some voo-doo happened to make it jump out of its spot, or if they reassembled it wrong when they replaced the filter.

Or why it woudl run..

The thing that kills me is that I had good pressure. But looking at the pressure port, it reads on the dirty side of the filter, not the clean side.

Re: Truck just died, running fine, then started sputtering, then would not start.

That standpipe valve should be open with the filter cap on and closed with cap off. Its only reason is so the crud will not go into the fuel system during a filter change. For it to run for the amount of time that it did it had to be somewhat open.
There was a bad run of filters produced at one time, that the hump in the top of the filter was not large enough to open valve.
Cannot figure out how your rod got into the side of the piston. Maybe the tech removed the standpipe for some reason?

Because of this description,(sounds like out of fuel, no cushioning effect on the injectors)
Quite a few posts back I posted "have we verified fuel"

I went back & re read the thread & it was 60PSI, I didn't want to get jumped on , so I deleted the post...I should have stuck with it.....


What a ride EH, I'm glad you got it going, I was totally dumbfounded....
What made you think to look in the bowl?....

Good catch, I saw that when cleaning mine, it would be nice if someone could make a new and improved write up of this fix.

Oops did not see I missed a page until I made this post.

Wow, what made you look there, good catch. Glad you got it running. Hope you did not throw away the sensors you replaced, could come in handy for yourself or a friend in the future.

Sure glad you got that figured out. I'd have never thunk to look there. Thanks for sharing the photos. I think we all learned something from this.

Your consolation is that not all of that $650 was wasted. AE will pay itself back eventually. [img]/forums/images/%%GRAEMLIN_URL%%/cool.gif[/img]

Re: Truck just died, running fine, then started sputtering, then would not start.

I learned a lot about how all this stuff works during this misadventure.. But I wish I had the $6500ish I spent back in my pocket

$360 for AE Scanner
$170 for new batteries
<u>$120</u> between pressure testers, miscellaneous doodads, tools
$650 spent fixing something the dealer put together wrong

Still no idea how/why it ran fine for 6 months and 5000 miles, and then just decided to tell me to pound sand.

Re: Truck just died, running fine, then started sputtering, then would not start.

Here is the first pic. This is the center post in the fuel filter bowl. I had to unscrew the heater to get it out. You can see the shell at the top, and the spring, valve, pin, and upper seat as they should be assemlbled. This valve closes when you unscrew the filter, to keep air out of the heads.

The next pic is what it looked like when I removed the filter. The last person to touch the filter was a tech at Duval Ford in Jacksonville, FL. That was in February, and it has run fine the whole time. The pin had the valve jammed closed. No fuel to the heads. Not sure how it got like this. It had been running fine.

This last pic show the alignment of how they were jammed together. It was straighter than this in the tube. But it was jammed together good. No idea how the heck they put it together like this, or why it was running fine for months.

Re: Truck just died, running fine, then started sputtering, then would not start.

Just got it running.. The fuel filter center post had a stainless pin sticking into the valve on the post, jamming it shut.

Damn dealer reassembled it wrong when they put a filter in back in Feburary.

Pics to follow soon.

Can't wait to hear how this ends up ! Twice in the last 3 months my 99' has just quit while driving down the highway. just quit like I put it in neutral and turned it off. after stopping and waiting a minute or so it starts right up????? I get weird dash lights now and again but nothing like this !

Thumper723 : I hope things start looking up for ya !

Getting a little bit of white smoke. Just a random puff here and there.

Re: Truck just died, running fine, then started sputtering, then would not start.

Cleaned the IPR. Nothing looked amiss.

Most recent start attempt:
ICP 2200 psi stable
IPR DC% 43-44%
Injector Pulse width 4.2-4.5 ms
Cranking at 160-180RPM
Vpower 11.7 volts while cranking.

Still sounds like a mistimed gasser.
