Sunday night I was heading to a buddies house (about 30 miles) and my truck started doing this thing where it seems like the filter is clogging/not getting enough fuel. It's loses power and makes a noise. (I guess it's the injectors clacking from no fuel+cylinders "dry firing")
So I pulled over and tried draining the filter. Not sure if anything at all came out. (It was dark and I didn't have a light) But it then quit doing it.
So Tuesday comes around I'm heading to my gf's parents house (maybe 7 miles) and it does it again. About ¾ ways there. So same thing, I pull off and try to drain the filter, but this time I have a bottle I drain it into. At first hardly anything came out so I shut it off, then got it to drain. All kinds of crap in it. Looks like rust/dirt.
So I head on and make it about a ¼ mile and it's doing it again, but this time actually died. So I finally got it started after a lot of cranking and switching to the front tank. Put $40 in fuel in at qt of the way, and it did fine the rest of the way.
When I got there I changed the filter and let it run for a bit.
Later when I went to leave, it died again at the entrance of the neighborhood. Cranked awhile again and got it started.
Well yesterday (Friday) I'm heading back to her house, and it does it again at about the same spot, just not as bad. So I slowed down and kept going, and it quit doing it.
On the way home, same thing but at the ¾ mark this way. Slow down into town and it quits doing it.
Drained it again but it's fairly clean. Just a few specs in it.
A few months ago I relaced the fuel pump with an airtex from autozone, which I believe is made by carter. When I replaced it, it had same symptoms leading up to failure, but it was all in the same day, and I believe was caused by a non venting fuel cap.
When I had it apart, I cleaned all the screens and the bowl itself.
There don't seem to be any leaks in the valley. The drain hose leaks when I open it. So I need to dry it up, then run it to see if it comes back while running, or only when I open the drain valve.
Does this sound like another failing pump? Or what?
I hate to change it again just to put another failure prone mechanical pump on, but as long as it gets me a few weeks to collect everything for an e-fuel setup, I would do it.
This is my 94 PSD.
I've been pumping fuel from my brothers truck being as his engine is blown, but his showerheads are broke off, so I don't see how I could've picked up trash from his tanks.
This all started running on the rear tank, which is plastic on my truck. My front is metal though.
Also I changed the oil Wednesday with TSC traveller 15w-40 all fleet diesel oil and mobil 1 filter.
Changed the rubber fuel lines between the pump and filter a few weeks after changing the pump.
Also no longer have the restriction sensor since they're so leak prone. I used a pipe plug and some sealant.
Tomorrow I'm going to see if I can find a fuel pressure gauge, or rent one of the testers.
