Another, with the crud/dirt on the intake and outtake valves.
Note the broken o-ring, maybe that was the air leak?

Thanks ichris, I need it!

Well, put everything back together. let the car idle for about an hour and a half with everything tightened up. Ran fine, no issues, beautiful sounding diesel.

Before I closed up the secondary housing I watched the lift pump and again there was no fuel going into the housing so I was thinking about what vstech said, we needed vacuum for the ip to draw fuel. When I primed it though it went nice and smooth and dumped into the secondary housing.

After the hour and a half, I went on my way, kind of expecting the worst but hoping for the best and went up that incline I spoke of in past posts and the same thing happened. The car dies on me in the same spot and the secondary filter housing was dry.

Also, something I had not mentioned before because I did not want to complicate matters.

I couldn't and I still can't get the car started after this happens. Before my issues I did not have this issue of non start. I thought it was an electrical issue, possibly battery, because it is a little smaller than I needed to crank the car and the battery was old. I thought because of all of the cranking, I was just doing a number on the old battery.

So I bought a brand new battery and now the starter does not engage or move -nothing- , just as before. Now, this issue is only after the car dies on me.

Man am I at a loss. The only thing I can think of is that there is not enough fuel in the tank, but I took off the sender and I can't see the top of the strainer, there's got to be more than 5 gallons in there.

I'm sure I am missing something, but I can't find any air getting into the system.

But now the car isn't even here, I have to wait a little bit and try to start the car.

I had a car if you ran the car too long the starter got too hot and it would not start until it cooled. Anyone have a similar problem?

Anymore ideas?

Thanks

I don't see how vstech's claim can be correct because people test their lift pumps and see how much fuel they pump while cranking so they are capable of pumping with no downstream vacuum.

I think you have two sperate issues now......when you rebuilt the lift pump, did you remove the large 30mm nut off the back? In your photo I see the cam lob still sticking out, indicating it wasn't fully disassembled.....

Lift Pump Rebuild...

I don't know Kerry, I'm just throwing things out there and letting everyone know what I did and tested.

Cooljay, I did remove the 30mm bolt and removed the spring and replace it.
I replaced the two valves, o-rings and cleaned out all of the gunk.

That cam you speak of, it did roll freely, but it was in a stationary position in relation to "pivoting," so to comment on your comment that it is sticking out. It did not move. When pushing on it, the cam did not push into the lift pump housing. I guess your telling me it should, I did not read the link you posted.

Thanks

Cooljjay,

After looking over that link, it looks like that roller sits on a piston and that spring would regulate it allowing it to go back and forth.

So with all that junk in there, it must have seized it up, sound correct?

Stop your car on a steep hill or put it on ramps or something and check the lift pump under those conditions.

That is your problem.....that cam/roller is suppose to push in to the lift pump, when it does, you will hear it pump.....both the ones I had a that were used on my car with wvo had the same issue....it was froze solid, that is why I tossed them and got a known good one....

Another link to read and a picture of what is behind the cam

Correct.....it can also be pitted and rusted.....

Kerry, that's a good idea, but at the same time Cooljjay is on to something.

That piston was definately seized.

I'l have to take it out again and see if I can free it up and or get another lift pump - or both

Just an update, freed up the piston in the lift pump.

We'll try this again in a day or two.

I do hope the o-ring and freeing up the pump solves your issue.
if not, just let me know and a decent pump is on it's way.
