Fuel pump woes

[cordes]

The FP which came in my 600 crapped out on me so I threw an old stock one I had lying around in the tank. That ran well for a total of about 20 min before it has somewhat died on me too. Today I could energize the Z1 circuit and get it to run for a few seconds before it would not do anything for a while. I'm thinking it's on the way out for sure. Could there be anything electrically which would commonly cause a FP to die like this? I want to make sure I have everything ready for the new one after I make sure the ground is good back there.

A bad ground will over heat and kill a pump, check resistance from the pump plug ground to a chassis ground and to the battery

Thanks, I will do that.

I checked everything out and it looks like it was just a case of two bad really old pumps in a row. I guess I will need to spring for a 255 unless anyone has any ideas for a JY pump which will cost next to nothing and flow a lot of gas at higher FPs.

Is it completely dead or still supplying a bit of fuel? If it works, just find a Volvo/Audi with those inline pumps and run that with the intank unit,

It's pretty much dead, but thanks for the suggestion.
