Way far from me.

Has there been a filter screen on the pumps you have been installing? (you may find some number of them in the tank)
Here is exactly what I've been getting. Is that white strainer what your talking about? It comes with that.Originally Posted by DFlintstone
Maybe we are on to something here. I'm not sure a new assembly comes with the filter screen. (which is easy to knock off while removing the pump). Has there been a filter screen on the pumps you have been installing? (you may find some number of them in the tank)

Edit: also I just checked the ohms of the ground at it was perfect. I'll still make it extra shiny though.

I'm beginning to think there is no solution and I'm doomed.

The wire between the fuel pump and the flange. One probe at each end.

I don't know if my tester is broke but I'm not getting it to light up on anything. Even in my house. Maybe I'm doing it wrong although I've used it many times. I wonder what the odds are that it is the continuity.Originally Posted by cruiser54

The pump must be out to test this correct? Mines out but still plugged up. I will be checking for trash soon. I need to jack the back up first.

No, No, Continuity testing IS Ohms testing, like you were already doing. Continuity means it's connected, juice can go through it. Zero ohms is perfect continuity. Originally Posted by Chick-N-Picker

I think he's wanting you to check from the terminals on the pump, from there to where they meet the "harness" wires.

No. From the pump to the flange is a ground wire with a female spade terminal on each end. Measure from one end to the other with the key off.Originally Posted by DFlintstone

My family is telling me I can't fix it and I'll need to take it to a shop.

Anyway just checked it with key off and it had .01 ohms which is good.

I also told them that a shop wouldn't probably find anything but tell me it just needed another fuel pump assembly then in 3 weeks I'd be right back where I was and out of big money. That is if I had the big money too spend haha.

I will be checking in the tank for trash tomorrow when I get the back a little higher. After that I will have done everything that has been suggested.
Also I thought about what the previous owner told it did to him. He said he drove it and it started going out then he took it home.
He would crank it up and move around his drive way and it would die. He'd park back in shed. Then it got to the point it wouldn't start at all.
This is what it's basically doing to me except I never make it to the point that it won't start because I keep changing the pump. But it's definitely cutting off on me in on the roas after it starts humming and going out. Almost got me killed in early June.
I said all that to say that whatever is burning up the airtex pumps is the same thing that burned up the stock pump. So it's probably not going to do me any good to burn up a Bosch.
It has to be something simple because the jeep runs too good for 2-4 weeks. Then it hums for a week. Then it hums and starts cutting off.
